摘要：
A waveguide-integrated Germanium avalanche photodetector with 6dB sensitivity improvement and excess noise with k(eff)similar to 0.1 was demonstrated while operating with 12dB gain at around 3V bias voltage. The photodetector was monolithically integrated into front-end CMOS. (C) 2009 Optical Society of America
