Abstract

A germanium on silicon waveguide photodetector disposed on a silicon on insulator (SOI) substrate. The photodetector is incorporated into a section of a planar silicon waveguide on the substrate. The photodetector generates an electric current as an infrared optical signal travels through the photodetector.
