One additional layer worth calling out is how photonics and materials constraints reinforce this thesis.

As AI data centers scale, the challenge isn’t just compute, it’s the physical limits of moving data. Traditional copper interconnects are running into bandwidth, latency, and power-efficiency ceilings at scale. That’s where photonics becomes critical.

Companies like LITE (Lumentum) and photonics innovators play an important role in enabling higher-bandwidth, lower-latency optical interconnects that can keep pace with massive AI model growth. At the same time, companies building optical DSPs, co-packaged optics, and photonic interconnects are helping solve the bottleneck between chips, racks, and data center fabrics.

This isn’t just about faster chips, it’s about enabling the entire infrastructure layer to scale. The interplay between advanced silicon, optical connectivity, and materials engineering is a major structural driver of the AI build-out.
