NVIDIA invests $2 billion in Coherent to develop silicon photonics for AI data centers, part of a broader $4B push into optical interconnect technology.

NVIDIA is betting big on light. The chipmaker announced a $2 billion strategic investment in Coherent on March 2, 2026, aimed at developing next-generation silicon photonics technology for AI data centers. The deal represents half of NVIDIA’s $4 billion optical infrastructure push, with fellow photonics company Lumentum receiving the other $2 billion. The investment will expand Coherent’s R&D and manufacturing capacity to support what both companies describe as the “global buildout of next-generation AI data centers.” For NVIDIA, which has watched its data center revenue explode from $15 billion in fiscal 2023 to $193.7 billion in fiscal 2026, optical interconnects have become a critical bottleneck to solve. Here’s the problem NVIDIA is trying to fix: as AI models grow larger and GPU clusters scale into the millions, traditional copper-based connections between chips can’t keep up. They generate too much heat, consume too much power, and hit bandwidth limits. Silicon photonics—using light instead of electrical signals—offers a path to faster, more efficient data transfer between processors. The timing makes sense. NVIDIA just reported Q4 fiscal 2026 earnings showing $68.1 billion in revenue, up 73% year-over-year, with guidance pointing to $78 billion for Q1. The company’s Vera Rubin platform, shipping in the second half of 2026, promises 10x performance per watt improvements—but those gains depend partly on better interconnect technology. Major hyperscalers are projected to spend nearly $700 billion on AI data center infrastructure this year. NVIDIA is positioned to capture roughly 60% of that spending, but only if the supporting infrastructure can scale alongside its GPUs. The Coherent partnership addresses that dependency directly.…
