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 long-distance transmission through fiber short they enable the optical networks that form the global internet.

Coherents 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 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

We are seeking a motivated Summer Intern to support the Process Engineering team in the area of plasma etching for semiconductor device fabrication. The intern will assist engineers in developing monitoring and optimizing Reactive Ion Etch (RIE) and Inductively Coupled Plasma (ICP) etch processes used in the fabrication of laser and photodiode (PD) devices in a cleanroom environment.
