70 GHz, 2 A/W, Waveguide-Coupled Germanium-in-Silicon Avalanche Photodiode

Year: 2025

Type: conference-paper

Abstract: In this work, we report a waveguide Ge/Si avalanche photodetector achieving high 3dB-bandwidths of 70 GHz and 50 GHz at an O-band responsivity of 2 A/W and 3.6 A/W, respectively, combined with sub-$\mu A$dark current performance in a simple, Si-contacted lateral diode design.
