Abstract
A surface-illuminated photoconductive detector based on Ge0.9Sn0.1 quantum wells with Ge barriers grown on a silicon substrate is demonstrated. Photodetection up to 2.2ìm is achieved with a responsivity of 0.1 A/W for 5V bias. The spectral absorption characteristics are analyzed as a function of the GeSn/Ge heterostructure parameters. This work demonstrates that GeSn/Ge heterostructures can be used to developed SOI waveguide integrated photodetectors for short-wave infrared applications. Related Projects
