Optical Computing· 300308.SZ
The picks-and-shovels king of the AI buildout — #1 in optical transceivers with >50% of Nvidia's wallet and the lowest forward P/E of any peer — but it is a margin-taker squeezed between US chip suppliers it cannot displace (Broadcom/Marvell DSP, Lumentum/Coherent EML) and Nvidia's own CPO/in-house ambitions, and the price already discounts flawless 1.6T execution.
Optical Computing
A credible Oxford/Münster silicon-photonics team that pivoted from a losing optical-compute bet to the right one — all-optical circuit switching — and shipped a real 32-port product, but it is a ~£137M-valued, sub-$50M-raised minnow standing in a lane Nvidia, Lumentum and a $4.4B Lightmatter are all paving; WATCHING, not investable, until a named hyperscaler design win proves the silicon-photonic-OCS approach beats incumbent MEMS in production.
