Lumentum Holdings Inc. is an American manufacturer of optical and photonic products. It was created in 2015 as a spinoff from JDSU.
Lumentum was one of two companies created during a August 1, 2015, spinoff from JDSU (along with Viavi Solutions).
Lumentum is regarded as a leader in optics and advanced manufacturing. Broadly speaking, they are a communication component manufacturer. Among the end uses for their optical components are networking equipment for telecommunications and commercial lasers deployment for industrial, oversight, and scientific lab use.
Among their products is a class of transceiver described as an optical circuit switch that is part of the artificial intelligence hardware stack. They primarily produce optical and photonic products in two sectors of the economy: Cloud & Networking and Industrial Tech. In the former sector, they provide optical and photonic chips, components, modules, and subsystems. In the latter sector, they produce a broad spectrum of lasers.
