Abstract
We demonstrate a method for improving Ge-on-Si avalanche photodiode (APD) sensitivity by varying the geometry of the charge and multiplication regions to achieve lower noise current. The APD's, fabricated in a commercial silicon photonic process, demonstrate an improved signal-to-noise ratio (SNR) at 940nm wavelength.
