What it does

Lumentum makes optical and photonic products, including lasers, laser chips, optical transceivers and telecom optical components, plus lasers for industrial and consumer uses.

Why it matters

AI data centers move data between GPUs and switches over light, and Lumentum supplies the lasers and optical components behind that, including high-power laser sources for co-packaged optics. NVIDIA listed it in its silicon photonics ecosystem, and its revenue nearly doubled in fiscal 2026 as cloud and AI demand grew.

How it makes money

Cloud and network service providers, AI infrastructure providers and network equipment makers pay it for optical components, modules and lasers; industrial and consumer customers buy its lasers.

Geography

United States (San Jose, California)

AI stack position

AI chips and networking. The companies designing the processors, accelerators and networking equipment that do the actual computing behind AI, including GPUs like NVIDIA's, and the high-speed connections that link thousands of them together.
