光子学 Photonics
用光信号替代电信号在芯片内/芯片间传递数据的技术总称，是 AI 数据中心下一代互联的必经之路。
别名： 光子学／ photonics／ photonic／ silicon photonics／ 硅光
是什么
光子学 (Photonics) 是用光子替代电子来传输信息的工程领域。在 AI 数据中心场景里，最重要的几个子方向：
| 子方向 | 解决问题 |
|---|---|
| Pluggable Optics | 服务器之间的光纤连接（现在主流方案） |
| CPO 共封装光学 | GPU/交换机内部的高速 IO（下一代） |
| Silicon Photonics 硅光 | 把光波导直接做在 CMOS 工艺里（更远的未来） |
| Optical I/O | 芯片对芯片的光互联（最远的未来） |
为什么 AI 时代不可避免
传统电信号在 PCB 板上跑高速会面临三堵墙：
- 信号完整性：>112 Gbps 之后铜线衰减暴增
- 功耗墙：每提升 1 倍带宽，功耗约提升 1.4 倍
- 物理空间：GPU 周围的 IO pin 数量碰天花板
光子学一次性解决这三堵墙。代价是工艺复杂、上游材料（InP、特种激光器）稀缺。
Serenity 的视角
他把光子学定位为”AI 算力扩张的真正瓶颈环节”，并多次说”这是十年级别的结构性机会”。他的覆盖框架：
- 上游材料：$AXTI（InP 衬底）
- 激光器/光源：$SIVE（DFB/CW 激光器纯粹玩家）
- 光引擎/模块：$COHR、$LITE、$AAOI
- 系统集成：$NVDA、$AVGO
他特别警示：不是所有挂”光子学”招牌的公司都是真的。$POET 和 $IREN 被他点名为 “Fake it Until you make it” 的代表，提醒散户用”营收 / 资本支出 / SEC 文件”三件套去验证而不是看 PPT。

富士康拟联合投资以解决CW激光器等光子学瓶颈。
让人想起 $NVDA 与 $LITE + $COHR 的情况： 富士康（Foxconn）正在考虑联合投资，以避免上游材料短缺。 富士康互连技术董事长指出，连续波(CW)激光器和光纤是光子学领域最大的瓶颈。 看到这两个主题在行业评论中被反复提及，非常有趣。 几乎就像 X 上某个动漫角色关于 CW 激光器瓶颈的说法是对的。
英文原文
Reminiscent of $NVDA w/ $LITE + $COHR: Foxconn is now considering joint investments to avoid upstream material shortages. Foxconn Interconnect Chairman identifies CW lasers and fiber as the biggest bottleneck in photonics. Very interesting to see these two themes reiterated across industry commentary. Almost like a certain Anime character on X was right about CW laser bottlenecks.

博主看好光子学供应链，认为激光器光纤将重现内存超级周期。
花旗银行TMT团队：“激光器和光纤正被定位为‘下一个HBM（高带宽内存）’。我从2025年就开始谈论像 $LITE / $AAOI 这样的激光器公司，以及向连续波(CW)架构的转变，这领先于当前的行业共识。我完全同意Lightmatter和花旗的观点。仅供参考：激光器方面：$LITE / $SIVE / $AAOI / $COHR / $MTSI / 古河电工 / 住友电工是较知名的标的。光纤方面：$GLW / 古河电工 / 古河光缆 / 住友电工是较知名的敞口（显然供应链中还有更多）。*披露，个人对该主题有持仓。补充评论称：‘紧张的供应状况将支持这些资产的稀缺性溢价。’我们已经看到激光器价格上涨，正如今天在深圳CIOE 2026上看到的 $SIVE 渠道检查以及 $LITE 的财报评论所示。因此，我认为2027-2028年的光子学超级周期将非常类似于2025-2026年的内存周期。尤其是随着高盛修正后的估计显示，每GPU-ASIC的光学内容将显著增加……
英文原文
Citibank TMT: "lasers and optical fibers are being positioned as the "next HBM." I've been talking about lasers like $LITE / $AAOI since 2025... and architectural shifts toward CW, ahead of the current industry consensus. And fully agree with Lightmatter/Citi. Just for reference: For lasers: $LITE / $SIVE / $AAOI / $COHR / $MTSI / Furukawa / Sumitomo are your better known ones. For fiber: $GLW / Furukawa / Fujikura / Sumitomo are your more well-known exposure (obviously a lot more in the supply chain) *disclosure, personal exposure to theme With added commentary that: "Tight supply conditions will support a scarcity premium for these assets." We're already seeing price hikes with lasers as seen with $SIVE channel checks at CIOE 2026 Shenzhen today + $LITE commentary from earnings. So I think the 2027–2028 photonics supercycle will look a lot like memory did in 2025–2026. Especially as optical content/GPU-ASIC goes up significantly per Goldman Sachs revised estimates...

高盛在最近的一份报告中上调了全球光模块市场预测：- 2026年：677亿美元（上调33%）- 2027年：1314亿美元（上调81%）- 2028年：1485亿美元（上调115%）对于 $NVDA Rubin Ultra，高盛增加了其模型中每GPU的光模块数量：1.6T：0 -> 2；3.2T：3 -> 5。高盛还将2027年1.6T及以上产品的预测提高了61%……这也非常重大，预计硅光子( Silicon Photonics )渗透率为80%。因此，每芯片的光学内容更多 = 更多的连续波(CW)激光器，更多的绝缘体上硅(SOI)衬底，光学公司日子好过。
英文原文
Goldman Sachs in their recent note upgraded their global optical module market forecast to: - $67.7 billion (+33% revision) for 2026 - $131.4 billion (+81% revision) for 2027 - $148.5 billion (+115% revision) for 2028 For $NVDA Rubin Ultra, GS increased its modeled optical modules per GPU: 1.6T: 0 -> 2 3.2T: 3 -> 5 GS also raised their 1.6T and above forecast for 2027 by 61%... so that's also very material, with 80% silicon photonics penetration rate estimated. So more optical content per chip = a lot more CW lasers, more SOI substrates, happy optical companies.

分析美中博弈下，欧日企业在EUV及光子学领域的垄断地位。
所以……这是我对美中紧张局势的看法： 你拥有像这样的欧洲垄断企业： - $ASML（极紫外光刻机 EUV） - $SOI（光子学-硅基绝缘体 Photonics-SOI） - 蔡司 SMT（ASML EUV 供应商）、通快 Trumpf（ASML EUV 激光供应商） 日本拥有许多近乎/完全的垄断企业，例如： - TOK、JSR、信越化学 ShinEstu、富士胶片 Fujifilm 用于 EUV
英文原文
So... here's my take on US / China tensions: You have European monopolies like: - $ASML (EUV) - $SOI (Photonics-SOI) - Zeiss SMT (ASML EUV supplier), Trumpf (ASML EUV laser supplier) Japan has many near/complete monoplies like: - TOK, JSR, ShinEstu, Fujifilm for EUV

Marvell高管指出欧洲/日本是SiPH激光器供应来源。
$MRVL 光学工程高级副总裁兼首席技术官 Radha Nagarajan 在台湾半导体展上表示： 1. 以欧洲/日本作为硅光混合组件(SiPH)激光器供应来源的示例。 Marvell 的高管在举例 SiPH 模块的激光器供应来源时，脑海中想到的是欧洲，这非常有趣。 https://t.co/zB5pDH1XVC
英文原文
$MRVL SVP and CTO of Optical Engineering Radha Nagarajan, at Semicon Taiwan: 1. Names Europe/Japan for laser supply sourcing as examples for SiPH modules. Very interesting that Marvell's SVP had Europe in mind when giving examples of laser supply sourcing for SiPH modules. https://t.co/zB5pDH1XVC

GPRO拟并购光子公司进军AI光模块，博主对此跨界竞争表示意外。
什么……$GPRO 在宣布计划与光子学公司“Starman Optical”合并后上涨了 79.17%。 旨在为 AI 数据中心制造美国本土的 800G/1.6T 光收发器。 GoPro 试图与 $AAOI 竞争，这绝对不在我的雷达范围内。 https://t.co/5z2XXHaxvs
英文原文
What... $GPRO is up 79.17% after planning to merge with a photonics company "Starman Optical" To build US 800G/1.6T optical transceivers for AI data centers. GoPro trying to compete with $AAOI was definitely not on my radar. https://t.co/5z2XXHaxvs

批评 Sivers 管理层缺乏重组紧迫感，忽视光子学机遇。
@wannabepanacea 管理层的感觉与我日益脱节。Sivers 本可利用当前的瓶颈围绕光子学进行彻底重组。利用美国资本加速时间表，并借助纳斯达克(NASDAQ)推动 1.6T/共封装光学(CPO) 的进一步增长。但感觉不到紧迫感，尤其是在上市时间表上。我也真心不理解为何持续强调卫星通信(SATCOM)/无线业务，这部分本应剥离。或者那些相对于光子学总可寻址市场(TAM)而言微不足道的短期合同价值。完全没有提及 Ayar、格芯(GlobalFoundries) 以及美国投资者关心的任何其他大项目。
英文原文
@wannabepanacea Management feels increasingly misaligned with my expections Sivers could use the current bottleneck to radically restructure around photonics. Use US capital to speed up timelines, and leverage NASDAQ for further growth with 1.6T/CPO. But got no sense of urgency, especially on listing timelines. I also genuinely don't understand continuous emphasis on SATCOM/Wireless which would be better off divested. Or the near term contract values that are invisible relative to photonics TAM. Not a single mention of Ayar, globalfoundries, and any other big program that US investors care about.

梳理AI供应链瓶颈：内存、ABF、CPO及地缘政治动态。
一些我感兴趣的TLDR新闻摘要： 1. $GOOGL（漏看了）也联合$NVDA投资了联发科，参与其39亿美元融资。Google/Nvidia在投资眼光上真是“山羊”（顶级），从$SPCX到Anthropic都是如此。 2. 三星电机披露了7.789亿美元的MLCC（多层陶瓷电容器）订单；$CAPA（新MLCC ETF）也为无法访问韩/日/台市场的投资者提供了敞口。但关键在于，每个加速器所需的MLCC数量增加，可能预示着未来比人们预期更极端的瓶颈。 3. 中国渠道调查显示：行星滚柱丝杠、6D力传感器和灵巧手难以实现国产替代。其中行星滚柱丝杠的国产替代率最低。例如$SHA0.DE做行星滚柱丝杠。只是听听护城河挺有意思。 4. 据报道，三星约70%的内存产能已锁定至2031年/商品DRAM也陷入短缺 - 首尔经济日报。TrendForce预计2026年Q3服务器DRAM合约价环比上涨13-18%。SK海力士也公开表示内存短缺将持续至2030年。 5. $CXMT已开始小批量生产HBM3E，并据称实现了LPDDR6的大规模量产。这对传统DRAM短缺的暗示更为积极。 6. 思科在台湾SEMICON表示共封装光学(CPO)已准备好大规模部署；可插拔模块仍将是市场主流。$MRVL也表示客户正积极规划早在2027年扩大光学部署。 7. 闻泰科技 -> 收购安世半导体 -> 荷兰政府实际上剥夺了闻泰的控制权 -> 闻泰正通过中国法院反击。但安世3亿美元资产被冻结。当然还有更多地缘政治戏剧，总是很娱乐。$AAPL也明确指控OpenAI销毁关键证据...（更多乐子） 8. 关于SOI（绝缘体上硅）衬底$SOI的ASP（平均售价）上涨描述不多，但他们现在有10+客户参与LTA（长期协议），$2亿营收被称为“底线”，评论称客户更关心获得晶圆而非制造地。所以基本上随着硅光子技术在2027年起飞，现在进入产能预留阶段。 9. 一些渠道调查显示高功率MOSFET和大面积TVS二极管的交货期高达~52周。（$STM据报道也在8月23日实施了2026年第三次涨价） 10. 传统封装产能可能在2027年面临超过20%的缺口，“引线键合设备”成为主要瓶颈，本周早些时候已覆盖过，受益者如... 11. 声称所有六大ABF供应商2026年订单已满，交货期12-14个月，部分供应商拍卖剩余产能；$NVDA、$AMD和超大规模客户锁定ABF产能至2028年，并推动供应商规划2029-30年扩产。像Kinsus (3189)、Unimicron (3037)、南亚PCB (8046)、Ibiden (4062)等名字大概都很开心。 12. CCL（覆铜板）主导的层压板产品再次涨价10%-20%，今年第7次涨价（如建滔）。行业估计HVLP4铜箔短缺在2026年约48%/2027年43%，而Low-Dk/T-Glass交货期已延长至30周以上。 13. “(GaAs)衬底材料和砷化镓外延源材料在2026年第三季度也面临新一轮涨价，据报道比限制初期高出5到6倍。”“中国最近放宽了一些衬底出口管制”，但据digitimes称“InP衬底严重短缺”。只是些$AXTI相关更新。 14. $AMD和$AVGO据报道预订了PowerTech计划的大部分FOPLP产能，早于2027年中大规模量产。 15. $INTC考虑使用$INTC代工生产HBM4E基底芯片。但$SKHY直接回应称“部分内容与事实不符”。 16. “OpenAI囤积数万台$AAPL Mac mini和Mac Studio”用于强化学习。Anthropic也从$AMZN租赁Mac mini单元。Tim Cook退休有点可惜，但老哥表现确实“山羊”（顶级）。只是些随机有趣的笔记。
英文原文
Just some TLDR news I found interesting: 1. $GOOGL (missed this) also invested in Mediatek alongside $NVDA for their $3.9B raise. Google/Nvidia are goats with investments you look at $SPCX to Anthropic. 2. Samsung Electro-Mechanics discloses $778.9M MLCC deal / $CAPA (new MLCC ETF) also gives exposure now for folks without Korea/Japan/Taiwan market access. But thing is more accelerators x MLCCs per accelerator might indicate a more future extreme bottleneck than people expect. 3. China channel checks state: planetary roller screws, 6D force sensors, and dexterous hands resist domestic substitution. Then planetary roller screw as the top with lowest domestic substitution rate. eg. $SHA0.DE for planetary. Just interesting to hear moats I guess. 4. Samsung reportedly has ~70% of memory production capacity committed through 2031 / commodity DRAM has also fallen into short supply - Seoul Economic Daily. TrendForce expects server DRAM contract prices to rise 13-18% QoQ in 3Q26 SK Hynix also publicly stated the memory shortage lasts through 2030. 5. $CXMT has begun producing HBM3E in small quantities and reportedly claimed mass production of LPDDR6. Implications are even more positive for legacy DRAM shortages. 6. Cisco at SEMICON Taiwan said CPO is ready for mass deployment; pluggable modules will remain the market mainstay. $MRVL also said customers are actively planning scale-up optics deployments as early as 2027 7. Wingtech -> bought Nexperia -> Netherlands effectively removed Wingtech’s control -> Wingtech is fighting back through Chinese courts. But Nexperia got $300m of their assets frozen. More geopolitical drama of course, always entertaining. $AAPl also explicitly accused OpenAI of destroying crucial evidence... (for more fun) 8. Not much description around ASP hikes regarding SOI substrates $SOI, but they now have 10+ customers involved with LTAs, $200m revenue described as a "floor", comments about customers more concerned about obtaining wafers than where they are manufactured. So basically moving into capacity reservation now stages as silicon photonics takes off in 2027. 9. Some channel checks put lead times for high power MOSFETs and large area TVS diodes as high as ~52 weeks. ($STM also reportedly implemented its 3rd 2026 price increase on August 23) 10. Traditional packaging capacity could face a deficit exceeding 20% by 2027" with "wire bonding equipment" emerging as the primary bottleneck", covered this earlier this week with beneficiaries like 11. Claims that all six major ABF suppliers are booked for 2026, with 12-14 month lead times and some suppliers auctioning remaining capacity; $NVDA, $AMD and hyperscalers locking ABF capacity through 2028 and pushing suppliers to plan 2029–30 expansions. Names like Kinsus (3189), Unimicron (3037), Nan Ya PCB (8046), Ibiden (4062), etc are all probably happy. 12. CCL leading laminated board products increased by another 10%-20%, 7th price hike this year (eg. Kingboard). Industry estimates put the HVLP4 copper-foil shortage at ~48% in 2026 / 43% in 2027, while Low-Dk/T-Glass lead times have stretched beyond 30 weeks. 13. "(GaAs) substrate materials and gallium epitaxial source materials are also facing another round of price increases in the third quarter of 2026, reportedly 5 to 6 times higher than at the early stage of the restrictions." "China has recently eased some substrate export controls" but there's a "severe InP substrate shortage" per digitimes. Just some $AXTI related updates 14. $AMD and $AVGO reportedly booked most of Powertech's planned FOPLP capacity ahead of mid-2027 mass production 15. $INTC considering $INTC foundry for HBM4E base dies. But $SKHY responded directly that "some of the content is different from the facts". 16. "OpenAI Hoarding Tens Of Thousands Of $AAPL Mac mini and Mac Studio" for reinforcement learning. Anthropic has been renting mac mini units from $AMZN as well. Kinda sad Tim Cook retired, but dude had a goated run. Just random interesting notes

无视宏观波动，因AI资本支出强劲且需求失衡，坚持做多AI核心标的。
宏观环境显然在过去几个月削减了高贝塔AI的估值。但我试图专注于基本面。 如果你好奇我的看法： 我们看到了创纪录的长期协议(LTA)可见性： - 存储(至2031年)、光子学(至2029-2030年)等 - $NBIS、$SOL等，尽管资本支出巨大，但算力需求仍存在巨大失衡。 - 加上创纪录的预测（$NVDA 2027年增长70%，$SMCI新增服务器订单超600亿美元等）。 对比： 令人不安的宏观环境： - 沃什表示，如果核心通胀未明确回归2%，美联储“还有更多工作要做”。 - 7月PCE同比为3.7% - 7月就业报告新增就业减少2.3万，失业率4.1% - 10年期美债收益率高企/30年期创2007年以来新高 - 伊朗紧张局势持续 - 日元跌至160/韩国两次加息 且近期加息25个基点的概率为40/60。 这肯定会对融资产生影响，且第三/四阶效应太多，我个人无法完全映射。 我不是宏观专家，但我的看法是： AI建设将继续，预计明年上游投入超1.3万亿美元资本支出，流经许多瓶颈和卡点。 虽然市场削减了远期估值并转向当前盈利/防御性公司。 我不知道会发生什么，尤其是加息概率几乎五五开，且特朗普的帖子可能一夜之间改变情绪。 只要我没看到超大规模云厂商削减资本支出或需求波动的迹象。 尽管宏观波动，我保持做多，因为我想持有控制AI建设未来格局的公司。 如果宏观环境有任何好转迹象，高贝塔股通常恢复最快。
英文原文
Macro has clearly cut high beta AI valuations over the past few months. But I try to stay focused on fundamentals. If you're curious about my take though: We're seeing record visibility with - memory (2031), photonics (2029-2030), etc LTAs - $NBIS, solana:5aQcoaSyy7fnhvpRHasBUAMH2nL5tTjVrmFw6BeGmoon, etc. massive demand imbalance for compute despite capex spend. - combined with record projections ( $NVDA 70% growth 2027, $SMCI $60B+ new server orders, etc). vs. uncomfortable macro where: - Warsh said the Fed has "more work to do" if underlying inflation isn't clearly returning to 2%. - July PCE came in at 3.7% Y/Y - July jobs report payrolls fell by 23k with unemployment at 4.1% -10Y Treasury high/ 30Y highest since 2007 - Iran tensions continuing - Japan Yen weakened to 160/ 2 rate hikes in Korea And with rate 40/60 in favor of 25BPS near-term hikes. There's definitely implications on financing + too many third/fourth order effects for me to personally map. I'm not a macro expert but my take is: The AI buildout will continue w/ $1.3T+ capex poured upstream expected next year, flowing through many bottlenecks and chokepoints. While markets chopped off forward valuations and rotated toward currently profitable/defensive companies. I don't know what's going to happen, especially since rate hike odds are almost a coinflip, and Trump posts can change sentiment overnight. As long as I don't see indicators of hyperscalers cutting capex or demand wavering. I'm staying long despite macro volatility, since I want ownership of the names controlling the future of the AI buildout. And if there's any indicators of better macro climates, high beta are typically the fastest to recover.

博主庆祝瓶颈论点获验证，硅光子普及促成多项新产能协议。
@AizuddinAl4653 这需要你自己估算！我不想给出市值(MC)估算，尤其是当人们可能会误解模型时。我只是在庆祝“瓶颈(chokepoint)”论点得到了外部评论的验证，这些评论提到了类似垄断的市场份额数据。而且，由于硅光子(silicon photonics)的大规模采用，这一瓶颈已经转化为可能带来10多项新长期协议(LTAs)/产能协议。
英文原文
@AizuddinAl4653 That’s for you to estimate yourself! I don’t want to give MC estimates especially if people misinterpret the modeling I’m just celebrating that the chokepoint thesis was validated by external commentary around monopoly-like market share figures. And since the chokepoint converted into likely 10+ new LTAs/capacity agreements because of siph mass adoption.

Soitec 产能协议进展顺利，硅光子衬底垄断地位确立。
还记得我关于 $SOI 的论点吗？Soitec 今天的采访评论： - 预计 1-2 周内将敲定 80% 的产能预留协议，总数超过 10 份。 - $2 亿的光子学-SOI 营收现在被描述为“绝对底线”。 $TSM 也认为硅光子集成 (SiPH) 将在 2027 年成为主流，市场份额将超过光收发器市场的 50%+。 如果你在一个瓶颈环节占据垄断地位： （瑞银估计 Soitec 在支撑硅光子芯片的衬底市场占据 95% 份额） 收入通常会流经你。
英文原文
Remember my $SOI thesis anon? Soitec interview commentary today: - 80% of capacity reservation agreements expected within 1-2 weeks, with more than 10 in total. - $200M Photonics-SOI revenue now described as "absolutely a floor" $TSM also sees SiPH going mainstream in 2027 with market share topping 50%+ of the optical transceiver market If you hold a monopoly-like position over a chokepoint: (UBS estimates Soitec has 95% share of the market for substrates underpinning silicon photonics chips) Revenue usually flows through you.

总结SIVE基本面，批评其沟通策略，看好其作为CPO激光供应商的高增长潜力。
以下是我对 $SIVE 来自 ER 的观点与基本面的最终总结： 2027年可插拔光模块（1.6T 爬坡）： - $JBL（1.6T LRO，已确认）2027年上半年订单，下半年爬坡 -> -> 可能有多家超大规模云厂商客户 - 3家可插拔制造商（评估中） - 3家可插拔制造商（供应评估中） 2027年下半年至2028年+的参考设计： - $GFS（格芯）SCALE（已确认） -> -> 可能包括 $AMD 和其他超大规模云厂商作为共封装光学(CPO)客户 2027年外部光源/光引擎： - $POET（已确认） -> -> Lumilens / 超大规模云厂商终端用户 - O-Net（已确认） -> -> 超大规模云厂商+亚洲地区的巨大ODM/OEM - 可能包括 $AEVA（映射） -> -> 向光引擎供应 -> 超大规模云厂商/激光雷达 - SemiNex（已确认） 2028年光I/O： - Ayar Labs（已确认） -> -> 可能包括 $AMD、ALchip 和超大规模云厂商ASIC项目终端用户 + $NVDA NVLink - $MRVL Celestial（2023-2024年披露的潜在客户） - Lightmatter（2023-2024年披露的潜在客户） - Lightelligence（2023-2024年披露的潜在客户） 随后可能在2028年为 $AAPL 下一代可穿戴设备更新及其他来自 TFLN 与 Lightium 的项目供货。 关于产能分配： - Win Semi - 1家其他晶圆厂（拥有巨大分配量） 在磷化铟(InP)连续波(CW)DFB激光器短缺期间。 这些都是持续的发展/资格认证，因为 Sivers 正瞄准2027-2028年的下一代硅光(SiPH)+CW以及1.6T和CPO。 尤其是高盛模型显示CPO机会将从目前的近乎零增长到2028年约910亿美元的市场规模(TAM)。 然而我的批评是： => 主要焦点未向西方受众传达2027-2028年光学爬坡的经济规模。 => 应停止围绕纳斯达克上市的模糊法律帖子，并设定明确方向+更快执行。 => 过多关注于辩护较小的当前收入/过去十二个月(TTM)收入/管道转化（allspace, Tachyon），相对于未来的资格/合作伙伴规模/产能/潜力。 $SIVE 需要将自己定位为一家面向未来的、全球高增长的光学公司，为超大规模云厂商项目供应激光器。 不要让叙事被向后看的指标主导。 正如摩根士丹利所言……“关键[CPO]参与者包括……$LITE、$COHR 和 Sivers 激光供应”。 我个人是 $SIVE 的愉快股东，以高贝塔值暴露于2027-2028年的1.6T/CPO光学变革。
英文原文
Just my final recap on thoughts + fundamentals of $SIVE from ER: Pluggables (1.6T Ramp) for 2027: - $JBL (1.6T LRO, confirmed) Orders H1 2027, Ramp H2 2027 -> -> Likely multiple hyperscaler customers - 3 pluggable makers (evaluation) - 3 pluggable makers (supply assessment) Reference Design for likely H2 2027–28+: - $GFS (Globalfoundries) SCALE (confirmed)) -> -> Likely $AMD and other hyperscalers as CPO customers External Light Sources / Optical Engines for 2027: - $POET (confirmed) -> -> Lumilens / hyperscaler end users - O-Net (confirmed) -> -> Massive ODM/OEM for Hyperscalers + Asia - Likely $AEVA (mapping) -> -> supplying to OE -> hyperscalers / lidar - SemiNex (confirmed) Optical I/O for 2028: - Ayar Labs (confirmed) -> -> Likely $AMD, ALchip, and hyperscaler ASIC program end users + $NVDA NVLink - $MRVL Celestial (potential customer from 2023-2024 disclosures) - Lightmatter (potential customer from 2023-2024 disclosures) - Lightelligence (potential customer from 2023-2024 disclosures) Then potentially $AAPL for 2028 for next-generation wearable updates and other programs from TFLN with Lightium. In terms of capacity allocations: - Win Semi - 1 other foundry (with tremendous allocations) during an InP CW DFB laser shortage. These are all on-going developments/qualifications since Sivers is targeting next-generation SiPH + CW with 1.6T and CPO for 2027-2028. Especially as Goldman Sachs models the CPO opportunity going from effectively near-zero today to ~$91B TAM by 2028. However my criticisms were: => Main focus was not on communicating economic scale of 2027-2028 optical ramps to Western audiences. => Legal vagueposts around NASDAQ listing should be dropped, and clear direction should be set + executed faster on. =>Too much focus was put on defending smaller current revenue/TTM revenue/pipeline conversion (allspace, Tachyon.) relative to future qualifications/partner size/capacity/potential. $SIVE needs to position themselves as a forward looking, global hypergrowth optical company supplying lasers to hyperscaler programs. And not let the narrative get dominated by backward looking metrics. And as Morgan Stanley put it... "Key [CPO] participants include … $LITE, $COHR, and Sivers laser supply". I'm personally a happy $SIVE shareholder for high-beta exposure to the next 2027-2028 optical shift with 1.6T/CPO.

批评 SIVE 忽视美国投资者对增长潜力的关注，导致估值受限。
是的。我真的不明白为什么 $SIVE 仍然专注于瑞典本地市场的沟通和私募融资，而不是美国市场。面对瑞典受众时，你会遇到诸如“如何止血”、“为何不披露私人客户”、“为何聚焦光收发器（这很明显）”以及“非光子订单影响”等引导性或指责性问题。因此，CEO 三分之一的时间都在为“机会管道”的含义进行辩护。而美国分析师会追问：瓶颈期+ASP上涨/经营杠杆下的晶圆厂分配经济影响；这些分配带来的产能收入（美国分析师半数电话会议都问这个）；$GFS 的 NPO/CPO/可插拔规模影响及下游终端客户机会；Ayar 等 CPO 玩家 2028 年量产（刚融资 5 亿+）或 ELS 生产与 O-net 的 TAM 机会；6 家新可插拔玩家的规模，而非质问“为何不披露”；以及 CFO 关于上市时间表和 M&A TAM 扩张的法律声明。这样投资者才能感知 2027-2028 年的未来增长。相反，目前的问答框架聚焦于当前财务（美国投资者不关心）、非光子影响或对措辞的质疑，而非让美国投资者兴奋于 CW 激光瓶颈期的经济影响。$SIVE 在瑞典市场花的时间越多，其估值就越像瑞典公司。

Yes. I genuinely don't have a clue why $SIVE still focuses on local Swedish markets for communication/private fundraising. Over the US. The questions you get from Swedish heavy audiences include: - Leading questions like how would you "stop the bleeding" - "Why can't you disclosure your private customers" - Why focus on transceivers (it's obvious) - Implications for non-photonics orders So 1/3rd of the time, the CEO needs to be defending leading/accusatory questions around what "opportunity pipeline means" US analysts would have pressed: - Economic implications from 2 foundry allocations during a bottleneck + ASP hike/operating leverage - Around much capacity revenue would those allocations lead to (half of AOI calls are around those from US analysts) - $GFS NPO/CPO/pluggable scale implications and downstream end customers opportunities - Ayar / CPO player 2028 ramp (that happened to raise $500m+) or other products like ELS production with O-net and TAM opportunities there. - How big those 6 new pluggable players were, rather than asking "why can't you disclosure them" - Clarifying CFO legalposts around listing timeline and M&A TAM expansion opportunities So investors can get a sense of future growth for 2027-2028. Instead, the way leading questions are framed/answers, the entire calls were focused around current financials (which US investors don't care about), non-photonic implications, or skepticism of wording. Rather than exciting US investors about economic implications from their time in a CW laser bottleneck. The more time $SIVE spends in Swedish markets, the more they will be valued as such.

博主认为 $SIVE 凭借广泛的光子学客户验证和稀缺产能，是极具性价比的首选标的。
不，$SIVE 是我见过的最独特的 10 亿美元市值光子学公司。仅针对 AI 数据中心： - 为 $GFS SCALE（共封装光学(CPO)/近封装光学(NPO)/可插拔模块）提供参考激光器 - 披露了 7 项可插拔模块合作，其中 $JBL 为主要放量客户（H1 2027 时间表） - 与 O-Net 的外部激光源(ELS)路径 - 与 $POET 的 ELS 路径 - 向 Ayar 提供用于 CPO I/O 的激光器（现属 $NVDA nvlink 生态系统） - 为 $AEVA 提供激光器（其已与超大规模云厂商的光引擎供应商达成 NPO 协议） - Celestial/Lightmatter/Lightelligence（可能是 2023/2024 年的客户） - 与 Lightium 合作在薄膜铌酸锂(TFLN)上集成磷化铟(InP)激光器 此外，它在行业短缺期间拥有两项实质性的连续波分布反馈(CW DFB)激光器产能分配。也是业内少数几家 CPO 级激光器供应商之一。告诉我这个市值范围内还有哪家拥有如此多的持续资格认证、巨大的潜在市场(TAM)且身处光子学领域。就相对于行业内的资格认证路径而言，$SIVE 是我心中的第一选择。
英文原文
Nah, $SIVE is the most unusual $1B photonics company I've ever seen. Just for AI DCs alone: - Reference laser for $GFS SCALE (CPO/NPO/pluggable) - 7 pluggable engagements disclosed, with $JBL as primary ramp (with H1 2027 timeline) - ELS path with O-Net - ELS path with $POET - Lasers to Ayar for CPO I/O (now in $NVDA nvlink ecosystem) - Lasers for $AEVA (which now has NPO agreements with optical engine providers for hyperscalers) - Celestial/Lightmatter/Lightelligence (likely customers in 2023/2024) - InP lasers on TFLN with Lightium Then it has 2 substantial allocations for CW DFB laser capacity during an industry shortage. As well as one of the few CPO-grade laser suppliers out in the industry. Let me know what other player around this range has so many ongoing qualifications, a large TAM, and in photonics. $SIVE is the #1 for me in terms of MC relative to qualifications paths across the industry.

反驳将万亿市值英伟达与早期光子学公司直接对比的观点。
@Ingeltun 也许是因为 $NVDA 是一家市值超过 5 万亿美元的公司。 然后你把它和一家处于资格认证阶段、市值 10 亿美元的光子学公司做比较，而该公司的所有产能爬坡都发生在 2027/2028 年。
英文原文
@Ingeltun Maybe because $NVDA is a $5+ trillion dollar company. And then you're comparing that to a qualification stage $1B photonics company where all their ramps happen 2027/2028.

博主维持存储看多，减仓美光等高位股，转配光子学及低位传统存储。
我一直对2026-2027年期间的存储（Memory）持看多态度，涉及 $MU / 三星 / $SKHYNIX。即使听完 $NVDA 财报电话会，观点依旧不变。我一直极力辩护高端存储需求是结构性的，且对营业利润（Operating Income）有巨大的经营杠杆（OP）效应（尤其在伊朗紧张局势影响LNG/氦气时）。英伟达财报再次证实了我们对极端需求的认知，因为承诺支出从1190亿美元飙升至2790亿美元，主要由存储采购驱动。英伟达CFO也表示：“我们正经历存储的极端定价环境。”关于我的操作，2026年上半年我在存储板块极度超配：包括 $MU, $SNDK, 群联(Phison), $SIMO, 南亚(Nanya), Macronix, 华邦(Winbond) 以及 $EWY / 三星/海力士（涵盖HBM/DRAM + NAND + 传统DRAM/NAND + 控制器 + NOR Flash）。除了保留三星/海力士的多头头寸外，我减仓了其他持仓，因为我认为许多标的已重新估值（例如美光从$300涨至$1000+）。我认为最大的价格发现阶段已经结束，现在只是等待营业利润跟上（尤其是三星）的博弈期。我利用这段时间超配了光子学（Photonics）。但我认为我们正看到新一轮的涨价潮向下传导至“传统中的传统”存储如DDR2/DDR3，随着华邦等传统玩家退出部分领域。当价格涨幅最终达到环比40-60%时，这让我想起了当年 $SNDK 在DDR2/DDR3领域的极端行情。因此我开始建立 ESMT（7月年化市盈率1.9倍）和 Etron 的头寸。也许我们会在传统存储堆栈的更底层看到价格发现时刻（可能我会错），但这是我近期关注的领域。
英文原文
I've always been bullish on memory with $MU / Samsung / solana:SKHYhSjuRWHgikq8eRKbtBbpABgJSkd7ytQV14i9EQ3 for the 2026-2027 period. Same opinion, even after $NVDA call. And I've been fervently defending how high end memory demand is structural + OP for operating income (especially during Iran tensions around LNG/Helium). Nvidia earnings just reaffirms what we know about extreme demand since commitments went from $119B -> $279B largely driven by memory procurement. Nvidia's CFO also said: "We are experiencing extreme pricing conditions in memory." As for what I've done, H1 2026 I was extremely overweight in memory: With $MU, $SNDK, Phison, $SIMO, Nanya, Macronix, Winbond, and $EWY / SK Hynix (HBM/DRAM + NAND + legacy DRAM/NAND + controllers + NOR Flash). I trimmed down those positions aside from Samsung/SK Hynix longs, since I do believe many have been rerated (eg. Micron $300 -> $1000+ already). I think the largest price discovery period has played out, but just a waiting game for the operating income to catch up (esp u samsung) And I used that period to go overweight on photonics. But I do believe we're seeing a relatively newer cascade down into the "legacy legacy" memory like DDR2/DDR3 with the "legacy" players like Winbond leaving some of those segments. Where the price hikes finally hit the 40-60% Q/Q mark, which reminds me of the extreme $SNDK days, across DDR2/DDR3. Which is why I started up positions in ESMT (1.9x P/E from July annualized) and Etron. Maybe we'll see a price discovery moment further down the legacy memory stack (could be wrong), but that's the area I've focused on recently.

展望SIVE财报，重点关注光子学合作进展、JBL量产及纳斯达克上市计划。
很多人都在关注两天后 $SIVE 的财报。 我关注的重点： 1. 我希望看到更多关于光子学联合开发/认证/合同的可见性。 -> $AAOI 表示多家客户向他们咨询共封装光学(CPO)激光器（但不得不拒绝） -> $MTSI 表示许多客户咨询连续波(CW)产能（但要到2027年下半年才能上线） 所以请仔细阅读关于一家作为 $GFS 参考激光器供应商、为 $JBL 提供可插拔模块（如Intel Siph）、为Ayar提供CPO的公司。 并且处于独立供应商地位： -> 拥有独立的CW DFB供应（与Win semi合作） -> CPO级激光器。 如果有更多客户接近Sivers，这将是非常积极的信号。 2. 持续进展转化为量产 -> 我最兴奋的是 $JBL，这可能是2027年上半年主要的收入增长来源。 -> $AEVA 相比之下可能小得多，但应在2026年下半年有所贡献。 -> Ayar和光I/O玩家已表示2028年才大规模量产(HVM)，所以那里不太期待。 -> 其他可插拔玩家（来自上一份财报）的联合开发转化为认证->量产。 除此之外： 3. 纳斯达克上市 -> 我们已经得到了“未来几个季度”的时间表，所以不再需要进一步细化。得到更新总是好的。 4. 财务数据 -> 再次强调，对于处于认证周期的玩家，当前财务数据不是重点。提醒一下，本季度有一些一次性会计处理，这在表面上会影响数据。 主要看点是未来季度的量产爬坡。 -> 收入管道增加 -> 签署的任何早期量产合同 鉴于最近7000万美元的融资+自举稀释压力消除，资产负债表担忧应该已经消除。 额外惊喜： -> 关于已确保的配额的信息“例如，我们确保了大量的CW产能->鉴于当前的短缺，这将是极高的信号。 -> 重申AOI、Macom、Lumentum、Coherent提到的需求。“例如，我们获得的任何产能都将被需求填满” $AAOI 在表示2027年预计产能约4.71亿美元并重申收入指引后，股价从30美元暴涨至220美元（但随后进行了大量定向增发ATM）。 如果Sivers能给出一个雄心勃勃的多头案例+未来时间表（如2028年上半年）的满产能收入声明，那将很好，但不强求。 进一步的重新评级将有助于通过类似Cloud Light的并购来加速未来财报的收入。 显然Sivers有其他量产爬坡，但我认为光子学是市场主要定价的部分。 无论如何，对即将到来的事情感到兴奋。
英文原文
Lot of people were wondering about $SIVE earnings in 2 days. What I'm watching out for: 1. I'm hoping for more visibility on photonics co-development/qualifications/contracts. -> $AAOI stated multiple customers approaching them for CPO lasers (but had to turn them away) -> $MTSI stated many customers approaching them for CW capacity (but doesn't come online until H2 2027) So read through for a company serving as $GFS reference laser, $JBL for pluggables (ex. intel siph), to Ayar for CPO. And in a merchant position: -> with independent CW DFB supply (with Win semi) -> CPO-grade lasers. Is incredibly positive for more customers approaching Sivers. 2. Ongoing developments turning into volume -> I'm most excited about $JBL, which would probably be the main revenue ramp in H1 2027. -> $AEVA is likely much smaller in comparison, but should be a contributor H2 2026. -> Ayar and optical I/O players already stated 2028 for HVM, so not really expecting much there. -> Co-developments from their other pluggable players (from last ER) turning into qualifications -> volume). Aside from that: 3. NASDAQ listing -> We already got timelines for that "next few quarters", so it's not really a focus to narrow that down further. Always nice to get an update. 4. Financials -> Again, current financials aren't a focus for qualification-cycle players. Just a heads up, there's some one-time accounting this quarter, which affects things optically. Main thing is volume ramps for future quarters. -> revenue pipeline increase -> any early volume contracts signed Balance sheet concerns should be cleared now given their recent $70m fundraising + bootstrap dilution overhang gone. Bonus cookies: -> Any information about allocations secured "eg. we have substantial CW capacity secured -> would be extremely high signal given current shortages. -> Reiterate demand that AOI, Macom, Lumentum, Coherent stated. "eg. any capacity we get would be filled from demand" $AAOI had their massive $30 -> $220 rally after they stated like $471M expected capacity in 2027, and reiterated that into revenue guidance. (but then had a lot of ATMs) An ambitious bull case + full capacity revenue statement for future timelines like H1 2028 for Sivers would be nice, but not expected. A further re-rating would help for M&A with a Cloud Light type acquisition for revenue acceleration in future earnings. Obviously Sivers has other volume ramps, but I think photonics is what the market is primarily underwriting. Regardless, excited for what's up and coming.

硅光子+CW主导CPO，激光元件供不应求，2027-28年或现短缺。
@OnurKocerr 不，EML、CW、microLEDs 都是并行路线，硅光子+CW 是 2027-2028 年的主要商业化重点，尤其是共封装光学(CPO)。如果有的话，内存/光互连增加了激光供应商（包括 CW DFB）的总可寻址市场(TAM)。这些已经供不应求。因此，当 2027-2028 年到来时，我们可能会看到另一场类似内存的短缺……鉴于你的前三名未来两年已售罄，且像 $AAOI 这样的独立激光产能上线后正被内部用于光模块而非出售。
英文原文
@OnurKocerr No, EML, CW, microLEDs are all parallel tracks, with silicon phonetics + CW being the main commercial focus for 2027-2028, especially for CPO. If anything, having memory/optical links adds another material TAM increase across laser suppliers including CW DFBs. Which are already in short supply. So we'll likely see another memory style shortage when 2027-2028 comes about... Given your top 3 are already sold out for next 2 years, and independent laser capacity coming online like $AAOI are now being used internally for transceivers rather than being sold.

推测SK海力士CPO供应链涉及Ayar/Celestial及上游SIVE等。
既然大家都在愉快地猜测 $SKHY 共封装光学(CPO) 路线图供应链。 我来猜一下：SK 海力士正在评估 Celestial/Ayar。随后将重点评估第一代部署后的 microLEDs（微发光二极管）。 这两家公司其实已经在这方面工作了一段时间。 - Ayar 出现在 SK 海力士官网上，语境是光 <-> 内存链接。 - Marvell 正积极与 SK 海力士合作定制内存解决方案（猜猜现在谁拥有 Celestial）。 Celestial/Ayar 也被 SK 海力士链接的 Nature 论文引用，这在技术相关性上提供了一些佐证： (121): Stojanovic, V. A UCIe optical I/O retimer chiplet for AI scale-up... 这是 Ayar 的引用（Ayar 的 teraphy 光 I/O 芯片组），顺便提一下 Stojanovic 是 Ayar Lab 的联合创始人。 (123): Winterbottom, P. Photonic interconnect for accelerated computing celestial AI photonic fabric module (咳咳，Celestial) 还有更多线索，但我想保持篇幅简短。 关于更多上游受益者： -> 我仍然认为 $SIVE 是最清晰的受益标的，因为他们很可能同时供应给 Celestial/Ayar。 中介层/封装 IP 层... 人们曾猜测 $POET，但 Marvell 可能在宣布后今年就通过垂直整合将他们淘汰了。 鉴于他们在 Celestial 被收购前就拥有自己的 SiPH 中介层技术/集成 IP（例如 2023 年展示过硅光中介层） -> AMS Osram（我不持有），看起来他们正在这一领域共同开发，因为他们今年特意指出 HBM <-> 光学对他们来说是一个 TAM（总可服务市场）增长点。 TLDR：我认为 Ayar/Celestial 是 SK 海力士 CPO 路线图的候选者，然后 microLEDs 可能在 2029 年左右实现第一代后的商业化。（这纯属猜测） 顺便给量子点粉丝一点甜头，这篇论文引用了它 5 次。
英文原文
Since people are having fun speculating on $SKHY CPO roadmap supply chains. I'm gonna do my own guess and say SK Hynix is evaluating Celestial/Ayar. Then doing heavy evaluation into microLEDs past first-gen deployments. Both have been kinda working on it for awhile. - Ayar shown up in SK hynix's own website in the context of optical <-> memory links. - Marvell is actively working with SK Hynix in custom memory solutions (and guess who owns Celestial now). Celestial/Ayar are both also cited in SK Hynix's linked Nature Paper, which helps a bit with technical relevance: (121): Stojanovic, V. A UCIe optical I/O retimer chiplet for AI scale-up. In 2025 IEEE Hot Chips 37 Symposium (HCS) 1–22 (IEEE, 2025) - This is Ayar reference (Ayar’s teraphy optical I/O chiplet), Stojanovic is Ayar Lab's co-founder btw. (123): Winterbottom, P. Photonic interconnect for accelerated computing celestial AI photonic fabric module (cough cough Celestial) There's more breadcrumbs out there, but wanted to keep this relatively short-form. For more upstream beneficaries: -> I still think $SIVE is the cleanest read through since they're likely supplying to both Celestial/Ayar. The interposer/packaging IP layer... People were speculating $POET, but Marvell probably vertically integrated players them out this year after the announcement. Given they've had their own SiPH interposer tech/integration IP before Celestials acquisition (eg. presented a silicon-photonics interposer back in 2023) -> AMS Osram (which I don't own), seems like they're co-developing in this area given they randomly went out of their way this year to say HBM <-> optics was a TAM increase for them. TLDR: I see Ayar/Celestial as candidates for SK Hynix's CPO roadmap, then microLEDs being commercialized past gen-1 maybe 2029. (this is all speculation) Just to throw a bone to quantum dot bros, this got cited like 5 times.

AI资金回流高流动性板块，半导体供应链多处出现涨价与瓶颈。
我很高兴杠杆交易者们从AI股票撤出，转回高流动性板块和生物科技（如$MRNA），这样我们或许能更快看到复苏。 除此之外，一些要点摘要： - $EWY上涨，主要得益于SK海力士的回购（他们利润太丰厚了），以及三星晶圆代工约10-15%的涨价。 - $SKHY发布共封装光学(CPO)路线图？看来他们在做光子中介层与内存连接的技术，我得深入看看。 这可能会带来更大的潜在市场(TAM)扩张，以及更多供应链受益者（如激光器、光子集成电路(PICs)、封装）。 - $YMTC继长鑫存储(CMXT)成功IPO后，计划下季度寻求IPO。 中国IPO市场正从宇树科技到内存制造商全面爆发。 美国应该采取类似做法，而不是让公司在万亿估值时IPO。 - Tyntek涨停，鉴于光子领域光电二极管需求失衡，其订单可见度已至2028年。 Elazr总经理曾表示整个光学供应链面临严重短缺……我接下来可能会更关注高端光电二极管瓶颈。 - 摩根士丹利预测DDR4在Q3环比涨价50%，2026年Q4涨价10%+。（南亚/2408，旺宏/2344应该很高兴）。 - 据报道，中国推迟对台湾出口锗、石英基材料和钕磁铁的许可。 所以我可能会一边吃杯面一边研究那里的供应链中断问题。 - 高端PCB钻头短缺（仍在持续），凯美(5498)称AI数据中心、服务器和光通信正在推动PCB、HDI和封装基板的需求，同时钨价上涨。 尽管全球五大钻头制造商正在积极扩产，供应仍远低于整体市场需求。 只是最近发现的一些有趣内容，当然$MRNA的事也挺有意思。
英文原文
I'm glad the leverage bros moved from AI stocks back to Hyerliquid and biotech like $MRNA, so maybe we'll see a faster recovery. Aside from that just some TLDR stuff: - $EWY up, primarily from SK Hynix buybacks (they're just too profitable), and Samsung Foundry roughly ~10-15% price hikes. - $SKHY unveils CPO roadmap?? Apparently they're doing something with photonic interposer that links to memory, so I gotta look a bit deeper into this Probably going to be more TAM expansion, more supply chain beneficiaries (eg. lasers, PICs, packaging) off this. - $YMTC pursuing IPO next quarter following CMXT's successful IPO. The Chinese IPO market is just going brrr from Unitree to memory makers. US needs to do something similar rather than IPOing companies at trillion dollar valuations already. - Tyntek limit up there's now order visibility through 2028, given photodiode demand imbalance for photonics. Elazr GM did say the entire optical supply chain was facing major shortages... I'll probably look more at high-end PD bottlenecks next. - MS forecasts a 50% Q/Q price increase for DDR4 for Q3, and 10%+ increase for Q4 2026. (Nanya/2408, Windbond/2344, should be happy). - China reportedly delays clearance from germanium, quartz-based materials, and neodymium magnets To taiwan. So I'll probably have some fun looking into supply chains disruptions there over cup noodles. - High-end PCB drill shortage (still ongoing), Kawei (5498) said AI DCs, servers and optical communications are driving demand for PCBs, HDI and package substrates, while tungsten prices are rising. Though the world's five largest drill manufacturers are aggressively expanding capacity, supply remains far below overall market demand Just stuff I found interesting recently, obviously $MRNA stuff is too.

MRVL获GOOGL和AMZN巨额订单，印证其成为万亿市值公司的潜力。
$MRVL 授予 $GOOGL 购买价值 122 亿美元公司股权的期权。 “Marvell-Google 交易涵盖与 TPU 配套使用的广泛技术，包括运行 AI 模型的处理器、管理数据存储以及跨网络传输信息的设备。” 这可能转化为到 2033 年约 1200 亿美元的营收。 Marvell 在完成 Celestial 收购（用于光网络架构采购）后，也与 $AMZN 签订了单独的认股权证。 还记得 Jensen 说 Marvell 将成为下一个万亿美元市值公司的美好时光吗？ 看来 Nvidia 早就知道 Marvell 正通过认股权证“编织”进入所有超大规模云服务商的供应链。
英文原文
$MRVL gives $GOOGL options to buy $12.2B of the company. "The Marvell-Google deal covers a broad range of technologies used with TPUs, including processors that run AI models, manage data storage and move information across networks." Which could translate into ~$120 billion in revenue through 2033. Marvell also has separate warrants with $AMZN after their Celestial acquisition (for purchases of photonic fabric). Remember the good times when Jensen said Marvell would be the next $1T+ company? Seems Nvidia knew Marvell was "networking" its way into all the hyperscalers with warrants.

看好 $SIVE 作为高贝塔光通信标的，受益于激光器瓶颈及潜在并购。
@Blazedsin 是的，$SIVE 是我首选的高贝塔（High-Beta）光通信多头标的。 这是一家小型公司，为以下领域供应激光器： - 像 $JBL 这样提供可插拔模块的可插拔模块供应商。 - 与 $POET / O-Net 合作的外部光引擎（ELS）+ 光引擎。 - 与 Ayar 等公司合作的光 I/O 扩展。 - 像 $GFS 这样的光子代工（Photonic Foundries），涵盖 NPO/可插拔/CPO 等所有架构。 随着 Win Semi 的独立连续波（CW）产能投产，正值结构性瓶颈期……纳斯达克上市可能在接下来几个季度实现。 而且 CEO 确实懂行 + 与股东利益一致（在二级市场买入股票），稀释程度低就能完成这一切。 他们还暗示了并购（M&A），这对总可寻址市场（TAM）扩张很理想（看看 2023 年下半年 Cloud Light 并购 Lumentum 后发生了什么）。 然后你有 $MTSI，$AAOI 可能不会实质性参与第一代共封装光学（CPO）部署（参与者池较小）……行业目前面临连续波（CW）短缺，随后才是量产爬坡。针对中国竞争的监管顺风。 我不确定是不是只有我觉得，他们拥有理想的布局，主要缺点是仅在某个小型瑞典交易所上市，这损害了估值。
英文原文
@Blazedsin Yeah, $SIVE is my favorite high-beta optical long. You have a small company supplying lasers for: - Hyperscaler suppliers like $JBL with pluggables. - ELS + optical engines with $POET / O-Net. - Scale up with optical I/O with Ayar and others. - Photonic Foundries like $GFS across all architectures like NPO/pluggables/CPO. with independent CW capacity coming online with Win Semi during a structural bottleneck... NASDAQ listing likely in the next few quarters. And the CEO actually knows what he's doing + aligned with shareholders (in terms of buying stock on the open market), with low dilution to get all of this done. And they hinted at M&A, which is ideal for TAM expansion (look at what happened with Lumentum after Cloud Light H2 2023 M&A). Then you have $MTSI, $AAOI likely no meaningful participating in first-gen CPO deployments (smaller pool of players)... Industry CW shortages currently before volume ramp. Regulation tailwinds targeting Chinese competition. I'm not sure if it's just me but they have the ideal setup, main downside is that it's just listed on some small Swedish exchange and that harms valuations.

AI光通信供应链严重短缺，光子学或重演存储超级周期。
我们从 $LITE、$MTSI、$AAOI 的财报中均看到激光器/TIA/DSP等存在极端的供需失衡... 现在，Elazr 总经理在其投资者大会上表示： 光模块供应仍远远落后于市场需求，预计 AI 光通信供应链（AI optical supply chain）的紧张局面将持续数年。 - “整个供应链都缺货” - “供应仍远远落后于市场需求” - “短缺将持续到未来几年” “无论是 PCB、载板、激光芯片，还是相关封装产能，只要是 AI 供应链环节，几乎全部短缺。” 当需求可见度延伸至数年且供应链存在瓶颈时： 很难不认为光子学（Photonics）正在重演进入 2027 年的存储超级周期。
英文原文
We got $LITE, $MTSI, $AAOI all pointing to extreme demand imbalances with lasers/TIA/DSP/etc from earnings... And now Elazr GM at their investor conference stated: Optical supply is still far behind the market demand, the expected AI optical supply chain are likely to continue for years. - "the entire supply chain is out of stock" - "the supply is still far behind the market demand" - "the shortage will continue to the next few years" "Whether it is PCB, carrier board, laser chip, or even related packaging capacity, as long as the AI supply chain link, almost all are in short supply." When demand visibility extends for years with the supply chain bottlenecked: It's getting difficult not to see photonics echoing the memory supercycle entering 2027.

博主重申持有HPS.A，看好其变压器及光子业务前景，尽管当前浮亏。
@I_Am_Bloateds 我仍然持有这两家公司的头寸？我持有的标的不应影响你自己的决策。 Transformer（变压器）瓶颈目前正阻碍美国AI基础设施建设，干式和液式（后者情况更极端）的交货期都非常长。$HPS.A 的积压订单同比增长96.9%，鉴于其市场份额…… 我不认为它们会消失。 我很确定我在~170时分享过这个观点，它曾翻倍，但现在回调至240，不过每个人的成本平均价不同吧。 这家比利时公司主要是2028年上半年的CPO（共封装光学）/光子量产受益者。他们与IMEC合作进行的MTP工作，以$NVDA为终端用户处于评估阶段，应该非常有趣。 他们的CHIPS法案MEMS/光子设施也将于2028年下半年投产，800V转换明年应为任何碳化硅(SiC)相关业务带来实质性收入增长。 我亏损-31%，因为我的成本平均价高得多。但它们正接近替换账面价值远高于市值的水平。
英文原文
@I_Am_Bloateds I still have positions in both companies? What I hold shouldn't affect your own decisions. Transformer bottlenecks are stalling the US AI buildout now and lead times are very long for both dry and liquid (which is more extreme). Backlog is +96.9% Y/Y for $HPS.A and given their market share... I don't they're going anywhere. Pretty sure I shared this idea at ~170, it did 2x, but corrected back to 240 now, but cost average is different per person I guess. The Belgian company is primarily H1 2028 as a CPO/photonics volume ramp beneficary. And the work they're doing with MTP with IMEC for $NVDA as an end user in evaluation stage should be very interesting. Their CHIP act facility for MEMS/photonics also comes online H2 2028 too, and 800V transitions should bring them material revenue growth for anything SiC adjacent next year. I'm down -31%, since my cost average is a lot higher. But they're approaching levels where replacement book value is a lot higher than MC.

博主分享基于英伟达供应链瓶颈推导高贝塔标的的投资逻辑。
@KhalidIshaq85 至于黄仁勋/英伟达直接投资的公司： - $MRVL (Celestial)、$LITE、$COHR 用于光子学(Photonics)领域... - $CCXI (Agility) 用于人形机器人(Humanoids)领域。 我倾向于进行更复杂的投资，这是我的思考过程： -> 我知道共封装光学(CPO)主题即将到来 -> 英伟达锁定了所有连续波(CW)激光器的产能。 -> 也许，$AAOI、$MTSI、$AVGO、$SIVE、$SMTC 是剩余的西方CW玩家。 -> $SIVE 可能是最高贝塔(Beta)的敞口。所以那是我的个人多头头寸。 可能可以对其他主题做类似的分析。
英文原文
@KhalidIshaq85 As for names Jensen / Nvidia directly invested in: - $MRVL (Celestial), $LITE, $COHR for photonics... - $CCXI (Agility) for humanoids. I tend to do more complex investing, for my own thought process: -> I know CPO theme is coming next -> Nvidia secures all CW laser capacity. -> Maybe, $AAOI, $MTSI, $AVGO, $SIVE, $SMTC are remaining CW western players. -> $SIVE probably the highest-beta exposure. SO that was my personal long. Can probably do something similar for the other themes.

博主认为应跟随Nvidia指引，押注CPO及物理AI供应链。
我觉得AI投资比人们预期的更简单。因为$NVDA和Jensen几乎直接告诉大家未来是什么。但不知为何，几乎每次市场都要等到事情真正发生才认可？ 2025年的Nvidia：大量收购EML和激光产能。 市场当时嗤之以鼻：“光子学是泡沫，像量子计算一样！____公司是骗局，管理层可疑。” 一年后：$LITE +678%，$AAOI +475.12%，$COHR +260.7%，$AXTI +3,843.9%。 _ 2026年的Nvidia： 通过长期协议(LTA)大量收购CW/EML产能。转向800V。明确强调共封装光学(CPO)的转型。指出物理AI(Physical AI)是下一个主题。 市场现在：“CW玩家是 meme 股！800V和CPO短期内不会到来，人形机器人无利可图！” 嗯……我们看看2027年会发生什么。 我认为我会押注Jensen/Nvidia作为领先指标。

I feel like AI investing is simpler than what people expect. Because $NVDA + Jensen literally tells everyone what's coming. But somehow. Almost every. single. time. Markets dismiss it until it actually happens? Be Nvidia in 2025: Buys up EML and laser capacity. Markets dismissing it: "Photonics is a bubble and like quantum! ____ company is a scam with shady management" 1 year later: $LITE +678%, $AAOI +475.12%, $COHR +260.7%, $AXTI +3,843.9%. _ Nvidia in 2026: Buys up CW/EML capacity with LTAs. 800V shift. Extraordinary explicit about CPO shift. States Physical AI as the next theme. Markets now: "CW players are meme stocks! 800v, CPO is not coming anytime soon, Humanoids are not profitable!" Yeah... We'll see what happens in 2027. I think I'm putting my money on Jensen/Nvidia as the leading indicator.

IQE论点获验证，债务清零且获大厂订单，作者继续持有看多。
感觉今年2月我对 $IQE 的论点连同 $AXTI 等一起得到了验证。（我目前仍持有两者的多头头寸） 所以我减少了对它们的覆盖。但简而言之，更新如下： 今年早些时候，当我发布关于它的论点时，IQE 是光学供应链中一个陷入困境但关键的瓶颈环节，与 $LITE 等公司有关联。 自那以来： - $MTSI 签署了长期外延晶圆供应协议，并入股该公司，现在 IQE 已无银行债务（Macom 有可转债，但这是积极的） - $TSEM 签署了磷化铟(InP)外延晶圆协议。 - 管理层明确表示，其与 IQE 的协议是为了确保“该路线图所需的战略性 III-V 族外延晶圆供应” - IQE 签署了另一份约1400万美元的神秘 AI 数据中心合同。 我早期论点中仍在展开的部分是 IQE 将其潜在/未充分利用的产能转向 AI 数据中心领域，以匹配该领域的同行如 Landmark（这需要时间，如果我没记错的话，略多于一年的时间）。 还有一些国家安全层面的含义，我将避免谈论，但这使它们更加重要。 但基本上： 2025财年营收：9730万英镑 2026财年指引：超过1.265亿英镑 它们在光学领域再次快速增长，摆脱了银行债务/困境清算状态，并仍然是西方光学供应链中的关键瓶颈。 现在……随着与领先光子学公司的新协议带来营收增长，以及像 Macom 这样的玩家充当软性后盾。 通常在论点得到验证后，我只是坐享企业的增长。
英文原文
Feels like my $IQE thesis Feb this year got validated alongside $AXTI and others. (I still long on both) So I stopped covering them as much. But TLDR on updates: Early this year, IQE was a distressed but critical chokepoint in the optical supply chain with links to $LITE and others when I published my thesis on it. Since then: - $MTSI signed long term epiwafer supply agreements, took a stake in the company, now IQE is bank debt free (Macom has convertibles, but that's positive) - $TSEM signed agreements for InP epiwafers. - Management explicitly said its IQE agreement was signed to secure the "strategic III-V epiwafer supply required for that roadmap" - IQE signed another ~$14M mysterious AI DC contract. The only part that's still playing out with my earlier thesis is IQE converting their latent/underutilized capacity toward AI DC segment, to match peers like Landmark in the space (which takes time, like slightly over a year if I remember correctly). There's some national security implications that I'll avoid talking about that makes them more important. But basically: FY2025 revenue: £97.3m FY2026 guidance: over £126.5m They're rapidly growing again in the optical sector, out of bank debt/distressed liquidation state, and remains a critical chokepoint in Western optical supply chains. Now... with new agreements with your leading photonics companies for revenue growth, and players like Macom serving as a soft backstop. After a thesis gets validated, typically I just sit back and enjoy growth of a business.

AI产业链各环节财报强劲，需求与订单爆发式增长。
今天AI主题的财报简直疯狂，涉及$CRWV、$SMCI和$LITE。 Coreweave：荒谬的~1040亿美元+积压订单，这还不包括Q3初新增的250亿美元+客户协议。 Neoclouds（如Nebius、Iren等）的计算需求传导效应巨大。 Supermicro：荒谬的650-720亿美元营收指引，新增600亿美元+订单... AI数据中心建设的传导效应极其巨大。 Lumentum：营收从8.08亿 -> 10.1亿 -> 12.5亿美元攀升，运营利润率逐季增长。 光子学玩家一直在疯狂印钞。 简而言之：AI建设的每一层都在疯狂爆发，且体现在财报中。
英文原文
Insane earnings today for the AI theme with $CRWV, $SMCI, and $LITE. Coreweave: Absurd ~$104B+ backlog, which doesn't include $25B+ of new customer agreements added in early Q3. Compute demand read through for Neoclouds is enormous (For Nebius, Iren and others) Supermicro: Absurd $65-72B in revenue guidance, adding $60B+ in new orders... AI DC buildout read through is just enormous. Lumentum: $808M -> $1.01B -> $1.25B revenue ramp, with operating margins growing quarter after quarter. Photonics players just keeps printing. TLDR: Every layer of the AI buildout goes brrrrr, and it's showing up in earnings.

引用研究指出低频交易优于过度交易，建议散户保持信念避免恐慌抛售。
现在市场又在举办激光派对，从 $SIVE、OE Solutions、$LITE、Coherent 到 $AAOI。有一项有趣的研究：富达(Fidelity)和加州大学伯克利分校(UC Berkeley)的论文都指出，表现最好的投资者通常是那些…… - 偶然忘记账户的人（富达） - 不主动交易/不过度交易的人（低频交易者回报18.5% vs 11.4%）。 这不是建议，但这些轶事可能对散户阅读有帮助…… 因为我目睹了记忆、光子学或主题波动性的大量投降式抛售，导致散户在强劲反弹时没有持仓。 拥有信念通常也属于“不过度交易”阵营，因为这有助于在下跌时不过度交易，或看到补仓机会。
英文原文
Now that markets are hosting a laser party again from $SIVE, OE Solutions, $LITE, Coherent, to $AAOI. There’s a pretty interesting study: Both from Fidelity and a UC Berkeley research paper, that the best investors are the ones who either… - Anecdotally forgot about their account (Fidelity) - Didn’t actively trade/overtrade (18.5% return from infrequent traders vs. 11.4%). Not any advice, but some of these anecdotes might be helpful to retail to read in general… Since I witnessed a lot capitulation off memory, photonics, or thematic volatility, just for retail not have positions on a sharp recovery. Having conviction also usually people in that “not overtrading” camp, since it helps to not overtrade in drops or see opportunities to cost average.
