摘要

A Si-Ge waveguide avalanche photodiode with loop reflector has been demonstrated to enhance the responsivity without compromising the speed. It enables a responsivity of 1.12 A/W, a bandwidth of 25 GHz, a build-up time limited gain-bandwidth product of 296 GHz, and a highest gain-bandwidth product of 497 GHz.
