100 GHz Photodetector Module

At a Glance

  • high-speed photodetector module for > 1 T/bs PAM datacom, telecom and microwave photonics applications

Technical Background

High-speed photodetector modules are of interest for the development of next generation optical communication links in datacom and telecom. Since these R&D links are always a step ahead in terms of symbol rates, photodetector modules with a RF bandwidth beyond state-of-the-art are needed at the receiver side. Furthermore, the highspeed performance of the photodetector modules makes them applicable to microwave photonics. 

The photodetector chips inside the modules are based on mature InP technology and are fabricated at the
wafer process line of Fraunhofer HHI, offering Telcordia and space-qualified processes. The chips are packaged at Fraunhofer HHI facilities.
