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