NVIDIA’s $4B investment in Coherent and Lumentum reflects AI scale needs

NVIDIA is doubling down on optical networking investments, committing separate $2 billion investments to both Coherent and Lumentum to drive innovation in advanced optics technologies, including research and development, to enable next-generation AI infrastructure and systems designs.

The nonexclusive agreements with the two companies include an NVIDIA multibillion-dollar purchase commitment and future access and capacity rights for advanced laser and optical networking products.

Also, NVIDIA is investing $2 billion in the two companies to support research and development, future capacity, and operations as they build out its U.S.-based manufacturing capabilities.

Optical interconnects and advanced package integration are foundational to the next phase of AI infrastructure, as they unlock ultrahigh-bandwidth, energy-efficient connectivity across AI factories.

These expanded partnerships harness NVIDIA’s leadership in AI, accelerated computing and networking, and Coherent and Lumentum’s expertise in optical innovation and advanced manufacturing, enabling the two optical companies to scale their respective R&D and manufacturing capacity to support the global buildout of next-generation AI data centers.

“AI has reinvented computing and is driving the largest computing infrastructure buildout in history,” said Jensen Huang, founder and CEO of NVIDIA.

Optics' growing role in AI data centers

Coherent and Lumentum bring unique elements to the table for the NVIDIA partnership.

Yole Group wrote in an Industry Insights report that Coherent can deliver short-range, high-bandwidth optical networking, including PICs for optical engines, by designing and producing lasers, modulators, and silicon photonics components that interface closely with electronic switch ASICs.

Yole said that Coherent’s “tight opto-electronic coupling is exactly what co-packaged optics (CPO) architecture requires.”

Likewise, the research group noted that Lumentum’s laser component capabilities “position it well as CPO moves from roadmap to deployment.”

The CEOs of Coherent and Lumentum both praised NVIDIA's investment, which highlights the key role optics will play in AI-enabled data centers.

“This strategic relationship underscores Coherent’s role as a key enabler of next-generation AI data center infrastructure,” said Jim Anderson, CEO of Coherent.

Michael Hurlston, CEO of Lumentum, agreed and added that “we are also investing in a new fabrication facility to increase capacity and accelerate innovation” as part of its collaboration with NVIDIA.

Addressing the connectivity bottleneck

NVIDIA’s deals with Coherent and Lumentum reflect that the new hill the AI infrastructure community needs to climb is high-capacity connectivity.

Yole Group wrote that the investments in Coherent and Lumentum, the two $2 billion investments, “are a loud signal” that “the next bottleneck for AI infrastructure won’t be compute,” but “will be connectivity.”

The scale of AI clusters means that current copper and conventional architectures won’t be able to support not only the bandwidth needs of AI factories, but also the latency and energy-efficiency requirements of these facilities.

“That’s why NVIDIA is doubling down on advanced lasers and silicon photonics,” said Martin Vallo, Senior Analyst at Yole Group – Photonics. “The objective is clear: unlock the next generation of interconnect.”
