70 GHz, 2 A/W, Waveguide-Coupled Germanium-in-Silicon Avalanche Photodiode
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- <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mu A$</tex> dark current performance in a simple, Si-contacted lateral diode design.
