40Gbps optical receiver based on Germanium waveguide photodetector hybrid-integrated with 90nm CMOS amplifier

摘要

A receiver based on Ge waveguide photodetector wire-bonded to 90nm CMOS amplifier built in specialty SOI wafer demonstrates error-free operation up to 40Gbps. At 25Gbps the receiver achieved a sensitivity of −8.3dBm with 3.3pJ/bit power-efficiency.
