About Indium Phosphide (InP) Technology

The worlds 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 longdistance transmission through fiber optics. In short they enable the optical networks that form the global internet.

Coherents broad portfolio of InP components includes applicationspecific FabryProt lasers directly modulated lasers (DMLs) and tunable lasers. It also includes photodiodes for highspeed receivers and power monitoring. In 2022 we introduced 200 Gbps indium phosphide electroabsorption modulated lasers (EMLs) for highspeed datacenter transceivers. This design provides our customers with the most advanced robust and costcompetitive laser devices for their 800G and nextgen 1.6T datacom transceiver designs.

Our worldclass 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.
