About Indium Phosphide (InP) Technology

The world's communications infrastructure depends on semiconductor lasers, and particularly those based on indium phosphide technology. Indium phosphide lasers are engineered to emit at wavelengths that are optimal for long-distance transmission through fiber optics. In short, they enable the optical networks that form the global internet.

Coherent's broad portfolio of InP components includes application-specific Fabry-Pérot lasers, directly modulated lasers (DMLs), and tunable lasers. It also includes 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. This design provides our customers with the most advanced, robust, and cost-competitive laser devices for their 800G and next-gen 1.6T datacom transceiver designs.

Our world-class and highly reliable InP technology platform is one of the very few in the industry that has been proven, with more than one hundred million lasers in the field deployed over the last decades.
