Not Accessible

Your library or personal account may give you access

Abstract

A waveguide-integrated Germanium avalanche photodetector with 6dB sensitivity improvement and excess noise with keff ~ 0.1 was demonstrated while operating with 12dB gain at around 3V bias voltage. The photodetector was monolithically integrated into front-end CMOS.
