Waveguide-integrated Germanium avalanche photodetector for low-noise and high-speed operation
Abstract
A waveguide-integrated Germanium avalanche photodetector with 10dB gain and excess-noise factor with keff below 0.2 was demonstrated. Gain-bandwidth-product of 350GHz was achieved at 3V. The single-crystalline Ge waveguide was integrated utilizing rapid melt growth technique. © 2010 Optical Society of America.
