About Indium Phosphide (InP) Technology
The world’s communications infrastructure depends on semiconductor lasers, particularly those based on indium phosphide technology. Indium phosphide lasers are engineered to emit at wavelengths optimal for long‑distance transmission through fiber optics, enabling the optical networks that form the global internet.

Job Description
Coherent’s broad portfolio of InP components includes application‑specific Fabry‑Pérot lasers, directly modulated lasers (DMLs), tunable lasers, photodiodes for high‑speed receivers, and power monitoring. In 2022, we introduced 200 Gbps indium phosphide electro‑absorption modulated lasers (EMLs) for high‑speed datacenter transceivers, providing our customers with the most advanced, robust, and cost‑competitive laser devices for 800G and next‑gen 1.6T datacom transceiver designs. Coherent’s world‑class and highly reliable InP technology platform has proven itself with more than one hundred million lasers deployed globally over the last decades.
