CMOS-integrated high-speed MSM germanium waveguide photodetector

A compact waveguide-integrated Germanium-on-insulator (GOI) photodetector with 10 ± 2fF capacitance and operating at 40Gbps is demonstrated. Monolithic integration of thin single-crystalline Ge into frontend CMOS stack was achieved by rapid melt growth during source-drain implant activation anneal. ©2010 Optical Society of America.
