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.
