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:

  1. 信号完整性:>112 Gbps 之后铜线衰减暴增
  2. 功耗墙:每提升 1 倍带宽,功耗约提升 1.4 倍
  3. 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。

  1. 供应链分析 $CRWV$LITE$SMCI

    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.

  2. 方法论 $AAOI$LITE$SIVE

    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.

  3. 供应链分析 $AMD$ASTS$CCXI$LITE$NBIS$NVDA$RKLB

    OCP峰会及财报周催化光模块机器人板块,Unitree IPO或带动机器人行情。

    近期的一些事件: - 明天是OCP亚太峰会(Ayar、Lightmatter、$AMD、$NVDA),你的共封装光学(CPO)概念股正在发布公告/更新。 这应该是某些光模块玩家的催化剂。 - 财报周:$ASTS、$RKLB今天发布(太空),$LITE周二(光子学),$NBIS在本周中段(Neocloud),还有更多。 - Unitree IPO认购今天开启,预计本月上市。 如果开盘良好,应是人形机器人+机器人板块的潜在催化剂,例如 $CCXI。 接下来的一周很有趣。

    英文原文

    Just some near term events: - OCP APAC tomorrow (Ayar, Lightmatter, $AMD, $NVDA) and your CPO players are giving announcements/updates. This should be a catalyst for certain optical players. - Earnings week: with $ASTS, $RKLB reporting today (space), $LITE on Tuesday (photonics), $NBIS in the middle of the week (Neocloud), and more. - Unitree IPO subscriptions opened up today and Listing is expected this month. Should be a potential catalyst for the humanoid + robotics sector if it opens up well eg. $CCXI. Fun week ahead.

  4. 个股论点

    博主维持对 Win 看多,看好其 InP 激光器及硅光代工在瓶颈期的增长潜力。

    @sunmingjun4 是的,我仍然对 Win (Win Semiconductors) 保持看多。在瓶颈期,他们正在上线磷化铟(InP)激光器的稀有独立产能(源自 Sivers),以及可能面向 AI 数据中心的硅光(PiC)晶圆代工服务(来自演示文稿)。我猜测其光学晶圆代工业务可能会在 2027 年起推动令人惊喜的收入增长。

    英文原文

    @sunmingjun4 Yep, I'm still bullish on Win. They're coming online with rare independent capacity for InP lasers (we know from Sivers) and maybe PiC foundry services (presentation slides) for AI DCs, during a time of a bottleneck. And my guess is its optical foundry might drive surprising revenue growth 2027 onward.

  5. 方法论 $AAOI$AXTI$COHR$LITE$MU$SPCX

    市场在瓶颈间轮动,基本面未变仅估值波动,建议理性看待。

    是的,我依然看好存储芯片,如 $MU / 三星。正如我之前所说,市场倾向于在瓶颈之间轮动。本周看来,光子学领域从 $AXTI 到 $LITE 再次成为焦点。关键在于……主要变化的是股价,随后辅以一些叙事和零星更新。对于光子学:> 在7月的下跌中,我们已经知道 $COHR / $LITE 的激光器已完全售罄,未来两年无货。> 我们从上季度财报电话会中已知 $AAOI 的需求失衡。7月崩盘期间,除了清算后的挂牌价外,基本面没有任何恶化。然而,当 $AAOI 跌至 $75 或 $AXTI 跌至 $35 时,许多人称其为“骗局”……但当它们涨回 $140 或 $80 时,人们又看多了,尽管光模块/磷化铟(InP)衬底瓶颈未变,甚至可能更糟(例如美国拟禁止中国新光模块,需求预测上调)。对于存储:我目睹大量散户投降,但这些人一个月前在 $MU 签署16份SCA并给出卓越指引时曾极度看多。或曾庆祝三星拥有全球最高营业利润。这里有一些更新,例如 Rubin Ultra 的存储优化(Nvidia每代都在追求),价格不再极端高于预期。但在当前价格下,营业利润相对于市值简直荒谬,尤其是存储成为结构性需求。明年的需求失衡应该更严重。人们倾向于在板块下跌时投降并跟随叙事(例如伊朗战争期间的氦气/LNG),即使瓶颈或基本面未变(例如 $SPCX Elon 财报电话会重申存储紧张)。我不能告诉别人该做什么:但 $140 的 $AAOI 和 $75 的 $AAOI 是同一家公司。市值 $1.5T 的三星和 $980B 的三星是同一家公司。只是估值和叙事(通常是噪音)在变,市场在板块间轮动。

    英文原文

    Yes, I'm still bullish on memory like $MU / Samsung. As I said earlier, markets tend to rotate from bottleneck to bottleneck. This week it looks $AXTI to $LITE in the photonics sector is the focus again. The thing is... the primary thing that changed are the stock prices, followed by some narratives + updates sprinkled in here and there. For photonics: > We already knew $COHR / $LITE lasers were completely sold out for the next 2 years during July's drop. > We knew about demand imbalance from $AAOI from last quarter's earnings calls. Nothing deteriorated fundamentally during July's crash, other than listed price after liquidations. Yet tons of people called $AAOI a "scam" when it dropped to $75, or $AXTI a "scam" on its drop to $35... But are bullish again at $140 or $80, when the transciver/InP substrate bottleneck hasn't changed at all, but maybe even got worse... (eg. draft for US ban on new china optical transceivers, scale up demand projections) For Memory: I'm witnessing a lot of retail capitulation, but the same people I'm seeing were mega bullish after $MU signed 16 SCAs and gave exceptional projections a month ago. Or were celebrating Samsung having the highest operating profit in the world. There's updates here and there eg. Rubin Ultra with memory optimizations (which Nvidia strives for every generation), with prices no longer being hiked way above expectations to the extreme. But the operating income relative to MC is just absurd around current prices, especially memory becomes structural. And the demand imbalance should be even worse next year. People tend to capitulate and follow narratives when a sector drops (eg. Helium/LNG back in Iran war), even if the bottleneck or fundamental situation hasn't really changed much (eg. $SPCX Elon earnings call reiterating memory tightness). I can't tell others what to to do: But $AAOI at $140 and $AAOI at $75 are the same company. Samsung at a $1.5T MC and Samsung at a $980B MC are the same company. Just valuations and narratives (often noise) change, and markets rotate from sector to sector.

  6. 供应链分析 $AAOI$AVGO$COHR$JBL$LITE$SIVE

    AAOI财报验证光模块需求远超供应,产能爬坡中,看好板块传导。

    以下是关于 $AAOI 财报的简要要点: - 预计超大规模客户将在未来几周内完成 1.6T 产品的全面认证(有助于收入爬坡 #2,时间线) - 继续认为 AOI 将拥有美国最大的 AI 数据中心光收发器产能(在竞争对手可能被禁时期重申雄心) - 预计磷化铟(InP)产能设施将于 2027 年初投产(进一步爬坡的时间线参考) - 总产能接近每月 20 万颗/单位,年底 800G/1.6T 达 65 万颗/单位。2027 年底达 93 万颗/单位(这是我想要看到的爬坡) - “增加外部光源(ELSFP)的制造产能。这是用于共封装光学(CPO)的”。我们预计今年晚些时候及 2027 年扩大生产,最终在 2028 年达到每月约 40 万件(需要时间将其建模为收入) - “如前所述,我们多年来一直内部制造激光器。这使我们避免了影响行业其他公司的短缺”(CW/EML 激光器短缺期间的垂直整合看多逻辑) - 我们相信未来 CPO 将继续推动对高功率激光器的需求增加(CPO 板块论点验证) - “长期目标是将非公认会计准则毛利率恢复到 40% 左右” - “第二季度末现金等价物总计 5.088 亿美元” 我需要再次确认 ATM 是否完成 - “我们交付收入的能力,特别是 800G 产品,目前受限于我们的生产能力”“如果我们能生产更多,我们现在就能发货更多” 需求 > 供应验证。 - “大部分增加的产能将在美国。即便如此,让我说,正如我一直强调的,这还不足以应对客户需求。客户需求高出 20%-40%。” 整个板块的光子学需求验证惊人,阅读 $LITE, $SIVE / $JBL 等公司的传导效应令人惊叹。 - “在未来两三年内不会,尤其是需求如此之大。好吧?即使结合 AI,$LITE, $COHR, $AVGO 加在一起,未来几年满足客户需求仍然非常困难” 更多光通信板块需求验证。 - CPO 时间线:“如果你说的是 CPO 市场的高产量制造商,我会说是明年第三季度末左右”以及“我们已与至少五家客户密切合作” 如果你关心当前财报(我并没有仔细看) 营收:1.91 亿美元 vs 1.90 亿美元 每股收益:0.06 美元 vs 0.02 美元 简而言之:激光器 + 光通信板块需求传导非凡。某种程度上支持 Lumentum CEO 关于激光器短缺比内存短缺更严重的说法。 2027 年产能爬坡按计划进行。要映射拐点期与时间线,大约在明年年初,正如他们之前的财报电话会议所述。 AAOI 现在拥有客户。限制在于制造足够的激光器和收发器。

    英文原文

    Just some TLDR notes on $AAOI earnings: - Expects full qualification of 1.6T products by their hyperscaler customer within next couple of weeks (helpful revenue ramp #2, timelines) - Continues to believe that AOI will have the largest AI DC transceiver production capacity in the US (reiterating ambitions during a time when their competitors might get banned) - Expects facilities toward InP capacity to come online in early 2027 (timeline FYI in terms of further ramp) - Total capacity is approaching 200,000/u per month, EOY 650,000/u per month of 800g/1.6t. EOY 2027, 930,000/u (this is the ramp i want to see) - "increase our manufacturing capacity for our external light source or ELSFP. That's for co-packaged optics or CPO". we anticipate ramping production later this year and into 2027, ultimately culminating in about 400,000 pieces per month in 2028 (need some time to model this into revenue) - "As we have mentioned before, we've been manufacturing lasers internally for many years. This has allowed us to avoid some of the shortages that have affected others in the industry" (vertical integration bull case during CW/EML laser shortages) - We believe that in the future, CPO will continue to drive increased demand for high-power lasers (thesis validation on CPO sector) - "to our long-term objective of returning non-GAAP gross margins to around 40%" - "We ended the second quarter with $508.8 million in total cash equivalents" I need to double check if the ATM finished or not - "our ability to deliver revenue in general, and specifically when it comes to 800G products, is limited by our production capacity right now" "If we could produce more, we could ship more right now" Demand > Supply validation. - "Most of the increased capacity will be in U.S. Even so, let me say that, like I keep emphasizing, that is not good enough for the customer demand. The customer demand is 20%-40% higher." Unholy photonics demand validation across the whole sector, read through for $LITE, $SIVE / $JBL, and others is amazing. - "Not in the next two, three years, especially the demand is so big. Okay? Even combined AI, $LITE, $COHR, $AVGO all together, it's still very tough to meet the customer demand in the next few years" More optical sector demand validation. - CPO Timelines: "If you're talking about really high volume manufacturer [for CPO market], I would say more like the late Q3 next year" and "We have been working very close with at least five customer" If you care about current earnings (which I'm not really looking at closely) Revenue: $191M vs. $190m EPS: $.06 vs. $.02 TLDR: Extraordinary demand across the laser + optical sector read through. Kinda supporting Lumentum CEO statement that laser shortage is worse than memory shortages. 2027 capacity ramp on track. To map inflection period with timelines, would be around early next year, as stated in their previous earnings call. AAOI has the customers now. Limitation is making enough lasers and transceivers.

  7. 个股论点 $TSEM$XFAB

    看好$XFAB作为早期$TSEM潜力股,CPO预期未计入模型。

    @jim29223471 是的,我的想法是 $XFAB 可能成为早期的 $TSEM,作为一家实际的碳化硅(SiC)/微机电系统(MEMS)晶圆代工厂,在他们发展光子学部门的过程中起到桥梁作用。他们重申了对共封装光学(CPO)的敞口,且2028年的时间表尚未被计入任何营收模型中(这一点我很欣赏)。可能还稍微有点早,但我们正接近2026年下半年的节点,且管理层指引(ER)非常有帮助。

    英文原文

    @jim29223471 Yeah my thought was $XFAB could be an early $TSEM with actual SiC/MEMs foundry kinda bridging the gap while they develop their photonics arm. They did reiterate exposure to CPO and 2028 timeline isn't priced into any revenue models yet (which I liked about them). Might be a tad early, but we're getting closer in H2 2026 and the ER statements were very helpful.

  8. 个股论点 $NVTS$POWI$XFAB

    XFAB确认CPO与800V布局,验证投资逻辑,预期2027-2028年估值重估。

    关于 $XFAB 投资者关系(ER)电话会议纪要: 简单回顾一下,我对 $XFAB 晶圆代工增长机会的观点源于碳化硅(SiC)在800V架构中的应用,以及光子工厂(MTP)在共封装光学(CPO)领域的适用性。 - $XFAB:“我们在共封装光学方面正在取得进展”。 - “向800V架构的过渡……预计将推动对碳化硅(SiC)和氮化镓(GaN)的需求……对 $XFAB 而言”。 所以,那些自信地唱空 $XFAB、声称其“在800V、光子学、CPO方面零敞口”的分析师/人士,结果被证明完全错了。 在我分享观点时,行业材料显示日月光(ASE)等公司将光子工厂+ $XFAB 列为欧洲即将崛起的CPO玩家。 filings显示他们普遍涉及如 $NVTS / $POWI 等名称。 很高兴 $XFAB 出面明确澄清,表示他们正在开发CPO/800V相关技术。 回到ER纪要: - “我们继续预计光子学量产将于2028年开始”。公司目前有三个硅光子项目正在与关键合作伙伴开发中。 我原本以为会在2027年下半年爬坡,但可能早估了几个月。 - 多个新的数据中心设计订单,例如3个新的碳化硅设计订单(与800V部署启动后2027年普遍爬坡一致)。 因此,一旦这些在2027-2028年爬坡(市场往往会提前定价),我预计 $XFAB 将基于增长机会获得估值重估。 总结: - 当前营收数据并不惊艳。 - $XFAB 确认直接涉足CPO和800V转型(这是投资逻辑的最大胜利) - 800V敞口带来的碳化硅机会(应在2027年) - 光子学量产时间表为2028年 很高兴CPO/800V敞口的投资逻辑在此次ER中得到确认。营收爬坡可能需要一点等待时间。

    英文原文

    For $XFAB ER transcript: Just to recap, my idea on $XFAB foundry growth opportunities stemmed from SiC for 800v and photonixfab/MTP for CPO applicability. - $XFAB: "We are making progress in co-packaged optics". - "The transition to 800v... is expected to support demand for both SiC and GaN... for XFAB" So those analysts/people that were confidently bearposting about $XFAB that they had "0 exposure to 800V, photonics, CPO" just turned out plainly wrong. At the time I shared my idea, industry materials showed ASE and others cited photonixfab + XFAB as an upcoming CPO player in EU. And filings showed they had exposure names like $NVTS / $POWI in general. So glad $XFAB went out to explicitly clear things up to state they were developing in CPO/800v. Okay back to the ER: - "We continue to expect photonics volume production to start in 2028". Company currently has three silicon photonics projects in development with key partners. I thought it would ramp sometime in H2 2027, but was probably early by a few months. - Several new data center design wins, eg. 3 new SiC design wins (consistent with general 2027 ramp as 800v deployment takes off). So once those ramp in 2027-2028, (markets tend to price things ahead of time), I'd expect $XFAB to be rerated based on growth opportunities. TLDR: - Current revenue numbers not as impressive. - $XFAB confirmed direct exposure to CPO and 800V shifts (biggest win for thesis) - 800V exposure opportunities for SiC (should be 2027) - Timeline is 2028 ramp for photonics volume production Happy exposure thesis to CPO/800V was confirmed from this ER. Might be a bit of waiting for revenue ramp.

  9. 供应链分析 $FORM$NVDA$TSM

    FORM财报显示CPO业务加速,处于早期爆发前夜,看好硅光子产业链。

    以下是 $FORM 财报电话会议中关于共封装光学(CPO)的一些有趣要点: 由于“共封装光学(CPO)的加速增长”,系统收入几乎翻倍。 2026年Q1:“我们现在预计2026年CPO收入将达到1000万至2000万美元区间的高位。” 2026年Q2(当前):“预计第三季度末将超过该区间,全年整体将显著超过2000万美元水平。” 管理层表示:“我们看到这项[CPO]业务正在显著加速。” 问:CPO采用前景。我们是否预期时间表会略微提前? 答:“我想说的是短期内确实有加速。”但管理层表示时间表没有显著提前。 引用生产基础设施(不仅是研发)用于: - 今年晚些计划量产的CPO芯片日益增长的出货量 + 用于扩展和扩展交换机的测试插入。 - 似乎CPO部分通过 $TSM 的 COUPE 流程 [可能对应 $NVDA 的CPO产品] - “CPO部分确实通过那10%的客户流向。” 因此,鉴于管理层提到CPO芯片出货量增长,测试环节正在爬坡。 “我们CPO业务的近期快速增长令人兴奋,我们认为这代表了硅光子技术在更广泛半导体行业中广泛采用的非常早期阶段。” 简而言之:从根本上说,CPO作为一个主题仍处于非常早期阶段,但由于它现在开始出现在财报中,应该很快就会爆发(设备/测试玩家通常会在光引擎/激光器出货量爬坡之前先出现)。 个人而言,一旦所有去杠杆过程停止,我认为市场将开始更加关注这一点。

    英文原文

    Just some interesting takeaways from $FORM earnings call on CPO: Since they attributed systems revenue nearly doubled due to: "accelerating growth in co-packaged optics or CPO". Q1 2026: "we now expect 2026 CPO revenues to come in at the high end of the $10 million to $20 million range" Q2 2026 (now): "expect to exceed that range by the end of the third quarter, and to significantly exceed the $20 million level for the year overall." Management stated "We’re seeing some significant acceleration in this [CPO] business". Q: CPO adoption outlook. Are we perhaps expecting the timeline to accelerate a little bit? A: "What I would say is there’s acceleration here in the very short term." But management stated there's not a significant pull-in on timelines. Citing production infrastructure (not just R&D) for: - The growing volumes of CPO chips planned for later this year + test insertion for scale-up and scale-out switches. - Seems like that CPO piece flows through $TSM COUPE [ likely maps to $NVDA CPO products] - "The CPO piece does flow through that 10% customer" So now, test is ramping given management cited growing volumes of CPO chips. "The rapid recent growth of our CPO business is an exciting development, which we believe represents the very early stages of widespread adoption of silicon photonics in the broader semiconductor industry" TLDR: Fundamentally, CPO as a theme is very early, and should start to go brrr soon since it's starting to show up in earnings now (equipment/test players usually appear up first before optical engines / laser volumes ramp). Personally once all the deleveraging stops, I think markets will start to care more.

  10. 供应链分析 $GFS$INTC$LITE$SIVE

    美政府注资GFS加速CPO研发,利好硅光子供应链标的SIVE和LITE。

    美国政府将持有 $GFS 1% 的股份,并授予其 3 亿美元用于美国《芯片法案》(CHIPS ACT)。 鉴于该《芯片法案》专门旨在推进共封装光学(CPO) + 硅光子技术(Silicon Photonics),这实际上是对 $SIVE / $LITE 的强烈利好映射(read through)。 (参考:Sivers 和 Lumentum 是 GFS 演示文稿中提到的唯二两家公开激光供应商。Sivers 激光阵列最近被指定为 Globalfoundries SCALE 用于 CPO 的参考设计。) 根据美国政府公告:“GlobalFoundries 将获得高达 3 亿美元,以将国内 CPO 研发加速两到三年”(NIST) 从未想过我们会看到美国政府 / $INTC 晶圆代工模式在特定 CPO 领域的应用...

    英文原文

    US Gov to take 1% stake in $GFS, and award them $300m for the US CHIPS ACT. This is actually a strong read through on $SIVE / $LITE, given this CHIPS ACT is specifically aimed at advancing CPO + Silicon Photonics. (For reference, Sivers and Lumentum were the only two public laser suppliers named in GFS presentation slides. Sivers laser arrays was named recently as a reference design in Globalfoundries SCALE for CPO). Per US Gov announcement: "GlobalFoundries will receive up to $300 million to accelerate domestic CPO R&D by two to three years" (NIST) Never thought we'd see the US Gov / $INTC foundry playbook for CPO in specific...

  11. 博主认为AI需求加速信号明确,短期波动属去杠杆,看好光互连及存储板块。

    我个人认为这是极短期的去杠杆行为,导致许多个股超跌。 - $BE 和 $TER 公布了超预期的业绩,Bloom 报告营收同比增长 166% + 利润率扩张 + 上调 2026 年指引... Teradyne 报告营收同比增长 104%,每股收益增长 300%+。 - 中国领先的光学玩家公布了惊人的初步财报,对西方光子学板块有极强的映射效应。 - 我认为财报季倾向于提醒市场 AI 加速仍在继续。我预计 $LITE、$SNDK / SK Hynix 以及板块龙头 ERs 将继续这一趋势。 - 但感觉市场更多是在奖励现有的加速,而非基于短期修正(如 $AMKR 所见)的未来一年增长。 - 总之,对我跟踪的主题来说看起来非常积极。 - 然后你有 $GOOGL 资本支出上调至 1950-2050 亿美元,这通常是超大规模云厂商最大的 AI 需求信号。 - 预测市场显示下次 FOMC 会议利率不变的概率为 77%。特朗普政府周一呼吁美联储降息。 - 所以今年三次加息的恐惧似乎有些夸大。 - 从 DUV 到 $CXMT 产能过剩的中国恐惧也被极度夸大。我们在每个行业都见过这种情况,直到人们记住激光或 HBM 瓶颈存在是有原因的。 - 就个人想法而言,看到所有东西一起涨跌是不健康的,尤其是这些主题。但我个人并不担心,因为我对我的持仓有充分信心,特别是像 $SIVE 或 $AAOI 这样的光互连领域。 - $META 计算和 $GOOGL GCP 利润率/增长显示出对 $NBIS 及类似新云业务模式的需求增加。 - $META 及其他超大规模云厂商关于与 $SNDK 和三星/SK Hynix、$MU 的长期协议(LTAs)的笔记指向结构性内存需求。 - 可以一直列举下去... - 但当 Jim Cramer 告诉每个保证金交易员在开盘时“全部卖出”,而新闻说存在 AI 泡沫时。 - 我讨厌别人说“它在跌所以卖出”。我相信重要的是看加速的营收/每股收益增长。如果营收加速与超大规模云厂商资本支出保持一致,那么该逻辑依然成立。 - 总之:我看到了 AI 需求/营收加速的迹象,超大规模云厂商资本支出是最重要的跟踪指标之一。 - 我猜我们会看到该主题广泛复苏。但我无法预测具体发生在哪一小时、哪一天或哪一周。

    英文原文

    I personally see it as extreme short term deleveraging that overshot many individual names. - $BE to $TER reported blowout results, with Bloom reporting 166% Y/Y rev growth + expanding margins + raised 2026 guidance... Teradyne reported 104% Y/Y revenue growth with 300%+ EPS growth. Your leading optical players over in China reported amazing preliminary earnings + extremely strong read through for the Western photonics sector. Think earnings season tend to remind markets about continued AI acceleration. I'm expecting $LITE, $SNDK / SK Hynix, and sector leader ERs to continue that trend. But it does feel like markets are rewarding existing acceleration more rather than future growth a year out over near-term revisions as seen with $AMKR. But as a TLDR, looks very positive for the themes I'm tracking. - Then you have $GOOGL capex raised to $195-$205B, which is typically the biggest AI demand signal from hyperscalers. - 77% 0bps change est. next FOMC decision from prediction markets. Trump administration on Monday called for the Fed to lower interest rates. So your 3x rate hikes fears this year seem kinda overblown. - Chinese fears from DUV to $CXMT overflooding are extremely overblown as well. We see this with every sector from time to time until people remember that lasers or HBM bottlenecks for a reason. As for personal thoughts, it was unhealthy seeing everything rise up or down together, especially with these themes. But I'm personally not worried since I have full conviction in my names, especially optical interconnects like $SIVE or $AAOI. $META compute and $GOOGL GCP margins/growth shows increasing demand for $NBIS and similar neocloud business models. $META + other hyperscaler notes around LTAs with $SNDK and Samsung/SK Hynix, $MU point to structural memory demand. Can go on and on... But when you have Jim Cramer telling every margined DC trader to "sell everything" at market open and news saying there's an AI bubble. I do hate it when others say "it's dropping so sell". My belief is that the important thing to look is accelerating revenue/EPS growth. And if that thesis stays in-tact with revenue acceleration in line with hyperscaler capex. TLDR: I see signs of AI demand / revenue acceleration, hyperscaler capex is one of the most important things to track. And my guess is that we'll see the theme recover broadly. But I can't predict what hour, day, or week that happens.

  13. 供应链分析 $AAOI$JBL$LITE$SIVE

    SIVE CEO称可插拔模块将长期存在,CPO为行业方向,激光器产能是瓶颈。

    不完全适用于 $AAOI(他们也在研发共封装光学(CPO),只是商业化进度稍落后)。 最近有一档名为“市场洞察:光子学与AI”的播客采访了 $SIVE 的CEO。 最有趣的观点是: “可插拔光模块在未来10年仍将存在”。 近期有很多关于CPO和RNG/MRC优化将蚕食可插拔模块总可寻址市场(TAM)的论点,但看来可插拔模块将长期存在。 而且未来会有多种架构路径并行(CEO也表示,除了CPO,非平面光学(NPO)在未来5年也是主要机会)。 至于挑战:Vickram表示,制造产能和原材料供应是主要瓶颈。这可能指的是上游连续波(CW)激光器扩产面临的现有瓶颈。 从播客来看,重点似乎放在可插拔市场,因为其短期TAM更大(考虑到 $JBL 和其他玩家,这可以理解),而CPO则是行业发展的北极星指标。 因此,如果 $SIVE 能通过并购获取更多可插拔光收发器IP(就像 $LITE 收购Cloud Light那样),可能会很有趣。 但简而言之: 未来路径多样,可插拔模块将长期存在,CPO似乎是行业发展的北极星方向。 感觉鉴于行业需求增长速度快于所有供应商的集体产能,合格的激光器供应商都有生存空间。

    英文原文

    Not exactly for $AAOI (they're working on CPO too, just a little further behind in commercialization). There's a podcast that featured the $SIVE CEO recently called: "Market Insights: Photonics & AI". Most interesting take was: "Pluggables will be around for the next 10 years". There's a lot of CPO + RNG/MRC optimization TAM cannablization arguments for pluggables recently, but looks like it's here to stay. And that there's going to be multiple architecture paths going forward (CEO also NPO alongside CPO as an major opportunity in the next 5 years). As for challenges: Vickram stated manufacturing capacity + availability of raw material is the main bottleneck. Likely referencing the existing bottlenecks with upstream CW laser ramp. From the podcast, seems like a large focus was on pluggable markets due to larger near-term TAM (which is understandable with $JBL + other players), with CPO being the north star. So it might be interesting if $SIVE M&A ambitions were to acquire more pluggable optical transceiver IP, like what $LITE did with Cloud Light. But TLDR: Lot of different paths moving forward, pluggable here to stay, CPO seems like North Star for where industry is heading. Feels like there's room for every qualified laser supplier given the industry demand is growing faster than what they can all collectively make.

  14. 供应链分析 $AMD$COHR$INTC$LITE$MU$SNDK

    AI算力瓶颈从CPU扩展至全产业链,长期协议锁定需求,利好瓶颈环节投资。

    $INTC 和 $AMD 将与中国客户签署针对 AI 数据中心 (AI DCs) 的 CPU 长期协议 (LTAs)(路透社)。据消息源称,年初以来部分 CPU 产品在中国的价格已上涨超过 40%。部分产品环比涨幅超过 10%。受 AI 推理 (AI inference) 的 CPU 配比影响,CPU 本身已是瓶颈。但更广泛的长期协议 (LTAs) 趋势似乎正从以下领域显现:内存方面,$MU、三星、$SNDK 和 SK 海力士签署 DRAM/NAND 长期协议;光子学方面,$LITE、$COHR 签署 EML 长期协议。且 Trendforce 近期报告称 $AMD 和超大规模云厂商正追求 CW 长期协议。我相信从 MLCC 到基板等更多领域也是如此。瓶颈投资者 +1……如果拥有跨越多年的“提货或付款”需求,很难成为“破裂的泡沫”。

    英文原文

    $INTC and $AMD to sign CPU LTAs with Chinese customers for AI DCs (Reuters). - Prices of some CPU products have risen more than 40% in China since the start of the year from sources. - Month-on-month increases topping 10% for some products CPUs were already a bottleneck, following CPU ratios due to AI inference... But the broader trend of LTAs seems to be appearing from: - Memory, with $MU, Samsung, $SNDK, and SK Hynix signing DRAM/NAND LTAs. - Photonics, with $LITE, $COHR signing EML LTAs. And recent Trendforce reports that $AMD and hyperscalers are now pursuing CW LTAs. And I'm sure there's many more from MLCCs to all the way to substrates. +1 for the bottleneck investors... hard to be a "bubble that pops" if you have take or pay demand spanning multiple years.

  15. 供应链分析 $GOOGL

    AI资本支出利好上游半导体,但市场担忧谷歌自身支出。

    @haranguetan_ 在评论之前,具备一点点阅读理解能力会有所帮助。 AI资本支出(Capex) -> 流向内存、光子学、晶圆代工厂等上游半导体领域。这些参与者乐在其中。 $GOOGL 本身正在花钱,所以市场可能不喜欢他们(指谷歌)这一点。 但对于接收这些资金的参与者来说,这是积极的。

    英文原文

    @haranguetan_ Having an iota of reading comphrension helps a bit before commenting. AI Capex -> goes to upstream semis from memory, photonics, foundries, and others. These players are happy. $GOOGL itself is spending the money, so markets might not like that for them in specific. But it's positive to the players that receive that capital.

  16. 业绩复盘

    博主澄清免费分享初衷,解释高杠杆组合回撤原因,看好AI结构性需求。

    谢谢!我一直免费分享个人研究和核心观点。不试图推销任何东西,也不告诉别人该怎么做。 最重要的是,我对自己的收益(无论盈亏)保持透明。 也许这种信息民主化让某些商业模式感到不安…… 当别人试图推销他们那永远正确、预测了半导体崩盘的40美元技术分析订阅时。 但如果他们真的相信这一点,他们早就通过买入看跌期权赚了5000%+,就不需要营销付费墙了。 是的,如果我使用1.4倍杠杆,且集中在存储/光子学底层资产的组合平均下跌35%……你会得到49%的回撤。 我只是分享发生了什么。 但我预计AI股会复苏,因为我看到从算力到能源、存储到网络的需求都是结构性的。

    英文原文

    Thanks! I’ve always shared personal research and core thoughts for free. Not trying to sell anything or tell others what to do. And above all, just being transparent about my own returns (win or loss) Maybe this information democratization upsets some business models… When others try and pitch their $40 TA subscriptions that are always right and predicted the semis crash. But if they really believed it, they would have made 5000%+ buying puts and wouldn’t need to market a paywall. Yes, if I’m on 1.4x leverage, and if a portfolio concentrated in memory/photonics underlying crashes -35% on avg… you get a 49% drawdown. I’m just sharing what happens. But I expect AI names to recover since I see demand from compute to energy to memory to networking to be structural.

  17. 方法论 $AAOI$INTC$MRVL$NBIS

    欧洲投资者保守晒2%收益嘲笑科技股暴跌,但反映的是文化差异而非技术判断。

    X平台的好处之一是能观察到文化差异:我看到一群欧洲旁观账户,躺着收银行存款利息,年内收益2%。现在冒出来说,当初投资$AAOI做光子学或三星做内存的都是赌徒。终于等到从$MRVL到$NBIS再到$INTC的所有AI相关股票在暴涨数倍后崩盘了,然后在那里庆祝。我认为主要是对技术变革缺乏理解,加上资本保值文化与成长型投资文化的碰撞。

    英文原文

    The nice thing about X is seeing cultural differences: I get a bunch of sidelined European accounts up 2% YTD off bank saving interest. Coming out of hibernation, and saying all along that investing in $AAOI for photonics or Samsung for memory is considered gambling. And celebrating when everything AI from $MRVL to $NBIS to $INTC finally had a crash after a few hundred percent rally. Think it’s mainly a lack of understanding of technological shifts mixed with capital preservation culture vs. growth.

  18. 供应链分析 $AAOI$LITE$SIVE$SOI$TSM

    高盛上调中际旭创目标价及盈利预测,看好硅光子及光模块产业链前景。

    谢谢,喜欢读评论! 高盛将中际旭创(Innolight)的目标价上调至2581元人民币。较当前估值约有163.6%的上涨空间。 但最大亮点是其2026-2028年的盈利预测大幅上调,分别增长65%/108%/119%,基于: - 硅光子模块出货量大幅增加 - 扩展、扩容、跨领域出货量增长 - 1.6T/3.2T提升混合平均售价(ASP)和利润率 - AI资本支出增加 这通常对光通信板块有重大传导效应,因为: 我倾向于将中际旭创视为类似台积电($TSM)的半导体资本支出风向标,用以观察光子学领域的状况。 例如,硅光子渗透率提高意味着连续波激光器(如$SIVE)和SOI晶圆($SOI)的总可寻址市场(TAM)扩大。未来代际产品的ASP上涨对其他光模块厂商也是利好。 我认为报告之外的另一个要点是,中际旭创在12日的电话会议中表示,800G需求的增长比预期更显著。 这反过来预示着$AAOI和$LITE等公司在下一次财报季将面临更多需求。 简而言之:高盛在大幅回调期间给出了高盈利预测。 从根本上说,当财报季(ER)到来时,更广泛的光子学生态系统应该会感到高兴。

    英文原文

    Thanks, love reading the comments! Goldman Sachs raised Innolight PT to 2581 RMB. Roughly 163.6% upside from current valuations. But the largest thing is its 2026–2028 earnings est revision raised by a whopping 65%/108%/119%, based on: - Much higher silicon photonics module volumes - scale out, scale up, scale across volumes - 1.6T/3.2T lifting blended ASP + margins - increase in AI capex This is typically very material read through on the optical sector since: I tend to think of Innolight as a $TSM (semi capex) type read on how the photonics landscape is doing. Eg. Higher silicon photonics penetration means more TAM for cw lasers like $SIVE (cw) / SOI wafer demand for $SOI. ASP hikes for future gen is positive for the other optical markers too. Think my other takeaway outside the report was Innolight stating 800g demand was growing more significantly than expected from their transcript on the 12th. Which in turn signals more demand for names like $AAOI to $LITE next earnings. TLDR: GS gives high earnings projections during a time of massive corrections. Fundamentally, broader photonics ecosystem should be happy when it’s ER time.

  19. 业绩复盘

    博主分享AI瓶颈板块近50%回撤,坚信长期逻辑未变并坚持持有。

    感觉糟透了,近期崩盘后本月最大回撤达-49.4%。 我的投资组合主要集中在人工智能(AI)的卡脖子环节和瓶颈领域。 包括存储、光子学机器人和上游半导体(使用杠杆),这些板块的贝塔值通常高于其他板块。但近期因崩盘已降低杠杆。 我看到很多人在嘲笑这次下跌或AI概念股,声称显而易见: - “AI是泡沫” - “存储/韩综指是泡沫” - “光子学是泡沫” - “人形机器人不会有前途” - “新云厂商将被Meta等超大规模云厂商取代” 还有一堆散户和机器人喊着“清仓,永远别想恢复”。 但我坚信所有这些主题都有结构性收入增长或技术变革作为支撑。 此前当政府威胁实施全球关税时,我也经历过类似的回撤,随后市场实现了复苏。 我个人拥有更长的投资视野和比他人更高的波动容忍度,以观察事态如何发展。 特别是考虑到许多散户以周为单位看待问题:不,如果我将收入拐点预测在2027年下半年,而现在才2026年,我的投资逻辑并没有错。 总之,短期感觉不好,但为了透明度还是想分享一下。

    英文原文

    Feels bad, -49.4% drawdown this month after the recent crash. My portfolio is mainly AI chokepoints and bottlenecks. In the memory, photonics, robotics, and upstream semis, (on margin) which all tend to be higher beta than others. But reduced leverage recently from the crash. I see a lot of people making fun of the drop or AI names, saying it’s obvious that: - “AI is a bubble” - “memory/kospi is a bubble” - “photonics is a bubble” - “humanoids won’t get anywhere” - “neoclouds will get replaced by hyperscalers like Meta” And a bunch of retail + bots saying “sell everything, it’s never going to recover”. But I have conviction that all these themes are backed by structural revenue growth or technological shifts. And I’ve had similar drawdowns back when there admin threatened global tariffs, before markets pulled off a recovery. I personally have a longer horizon + higher tolerance for volatility than others, to see how this plays out. Especially considering a lot of retail view things on a week to week basis: no, my thesis isn’t wrong yet if I project revenue inflection in H2 2027 and it’s 2026 now. Anyway, feels bad short term just wanted to share anyway for transparency.
