Overview
- In late May Nvidia disclosed at least $6.5 billion in commitments since March to firms building photonics tech, including $2 billion packages to Lumentum, Coherent and Marvell and $500 million stakes in Corning and Ayar Labs.
- Rosenblatt reported Nvidia asked suppliers to expand indium phosphide (InP) laser capacity roughly 20x through 2030 while suppliers proposed a smaller roughly 12x ramp.
- Nvidia says it is integrating silicon photonics into its networking and GPU‑to‑GPU interconnects to enable larger, more energy‑efficient rack and cluster designs, according to CEO Jensen Huang.
- Analysts warn manufacturing yield, precise optical‑to‑silicon alignment and complex co‑packaged optics packaging remain major barriers that could delay volume deployment until later in the decade.
- The push has re‑rated supplier stocks in 2026 and leaves markets watching Nvidia’s upcoming product roadmaps and Computex presentations for clearer timing and scale of photonics rollouts.
