Nvidia's $4B Photonics Bet Targets AI Bottleneck

Nvidia is escalating its full-stack dominance strategy with a $4 billion investment into photonics firms Lumentum and Coherent. This move is a direct acknowledgment that the next frontier of AI performance is not just in the silicon, but in the speed and efficiency of data movement between chips. By investing heavily in optical interconnects, Nvidia aims to solve a critical scaling bottleneck, positioning itself to control the entire AI data center hardware ecosystem, from processing to networking. This strategic investment puts immense pressure on competitors like AMD and Intel, whose standalone chip performance could be throttled by networking components they don
