Nvidia is committing $4 billion to photonics manufacturers Coherent Corp. and Lumentum Holdings in a move aimed squarely at scaling the backbone of its next-generation AI data centers.
Each company will receive $2 billion through a mix of direct investment, long-term purchase agreements, and guaranteed access to future production capacity for advanced optical components.
The goal is for Nvidia to secure enough high-end silicon photonics and laser technology to keep Nvidia’s AI infrastructure roadmap on track as model sizes and cluster scales keep climbing.
Nvidia disclosed that it plans to invest $2 billion apiece in Lumentum and Coherent, both key suppliers of optical and photonic components used in high-performance networking and data center interconnects.
Following the announcement, shares of Lumentum and Coherent went over 7% up, which reflected the investor expectations that Nvidia’s backing will translate into years of demand tied to AI infrastructure buildouts.
Why Photonics Matters for AI Data Centers
As AI training clusters grow from thousands to tens of thousands of GPUs, traditional copper-based interconnects are hitting bandwidth and power limits inside data centers.
Photonics, which uses light instead of electrical signals to move data, offers much higher bandwidth over longer distances with lower latency and better energy efficiency, making it a central technology for future AI “factories.”
Nvidia CEO Jensen Huang has described the work with Lumentum as an effort to develop some of the world’s most advanced silicon photonics to, in turn, “build the next generation of Gigawatt-scale AI factories.”
Inside the Partnerships with Lumentum and Coherent
Lumentum specializes in high‑performance optical and photonic components and will use Nvidia’s backing to expand research, development, and manufacturing, including a new U.S. fabrication facility focused on advanced silicon photonics and laser technology.
Coherent, another major optical components supplier, is also set to use Nvidia’s $2 billion for scaling production of cutting‑edge photonics for data center, cloud, and communications workloads closely tied to the growth and acceleration of AI.
What This Deal Means for Next-Gen AI Infrastructure
For cloud providers and enterprises building on Nvidia platforms, the investments in Lumentum and Coherent means that high-speed optical links will be deeply integrated into future AI systems, from GPUs to data centers.
The $4 billion commitment highlights that this kind of technology is now as central to AI performance as the GPUs themselves, and Nvidia wants that optical pipeline secured well in advance.
