Nvidia invests $4 billion into photonics firms in a bid to bolster data center interconnect supply chains — Lumentum and Coherent investment to fund U.S. R&D and manufacturing facilities, supports capacity rights and future access

Nvidia has pledged to invest a combined $4 billion in two photonic manufacturing firms, Lumentum and Coherent. As Reuters reports, this continues Nvidia’s plans to expend capital investment with its expansive cash reserves to help build the AI ecosystem and improve the output of its models. The quiet part is that it also helps keep Nvidia on the cutting edge.

Both companies develop optical and semiconductor technologies, enabling future networking hardware and AI chip designs that utilize light to transfer data, rather than electricity. With Nvidia looking to continue providing the digital shovels in this AI gold rush, leveraging forward-looking technologies like photonics may be one way it maintains its edge in the range of hardware spaces it now occupies in the global AI buildout.
