[News] Intel Claims Industry’s Only High-Volume 300mm InP Silicon Photonics Capability as CPO Gains Momentum - TrendForce

Intel's 300mm InP silicon photonics claim is not a product launch—it is a manufacturing chokepoint play in the CPO value chain. InP remains the only viable CW laser material for silicon photonics, and 300mm-scale production enables co-manufacturing of laser sources alongside photonic ICs on a single line, collapsing the current discrete-laser-plus-silicon-photonic-die architecture that Broadcom and NVIDIA ship today. The technical ripple is immediate: MOCVD equipment vendors face capacity lock-in, InP substrate suppliers (Sumitomo, JX Metals) are forced to scale, and AI interconnect roadmaps from 800G to 3.2T find their yield and BOM bottlenecks addressed by manufacturing scale rather than design innovation. The risk vector is structural: InP epitaxy tooling is concentrated among a handful of suppliers, and tightening export controls on compound semiconductor equipment could turn an industry-first into a single point of failure. Photonic integration players in China and Taiwan, China will accelerate domestic InP alternatives. On the competitive front, Broadcom's Bailly CPO is already in production and NVIDIA's co-packaged optics roadmap is aggressive. Intel's real card is building the laser segment competitors cannot replicate—but it lacks anchor customers. The more probable path is positioning this as a foundry differentiator, opening it to CPO startups and eroding Broadcom's vertical integration moat. Within 12 to 24 months, 300mm InP-on-silicon will commoditize from exclusive capability to industry infrastructure. Laser chip margins compress; value migrates to advanced packaging and system integration. Intel must lock in two to three hyperscale customers within this window or the asset becomes a slide-deck footnote.
