What is 10Gb/s Ge/SiGe Quantum-Well Photodetector about?

This paper presents a 10 Gb/s Ge/SiGe multiple quantum well waveguide photodetector. The device is 3 μm wide and 80 μm long and exhibits a dark current of 474 nA at a reverse bias of -1 V. At wavelengths of 1405 and 1420 nm, the device demonstrates a responsivity as high as 0.8 A/W, paving the way for using Ge/SiGe MQW structures as efficient active waveguide devices.
