Abstract:
A Ge-on-Si photodetector constructed without doping or contacting Germanium by metal is described. Despite the simplified fabrication process, the device has responsivity of 1.24 A/W, corresponding to 99.2% quantum efficiency. Dark current is 40 nA at −4 V reverse bias. 3-dB bandwidth is 30 GHz.

Claim (Index 25):
A photodetector, comprising:\n a substrate; a semiconductor layer on the substrate, including a waveguide extending therein; a first n-doped semiconductor contact in the semiconductor layer adjacent to the waveguide; a second p-doped semiconductor contact in the semiconductor layer adjacent to the waveguide; a first metal terminal, in electrical communication with said first contact and in electrical communication with external circuitry; a second metal terminal, in electrical communication with said second contact and in electrical communication with external circuitry; a light absorber, consisting of an intrinsic germanium body, mounted on the semiconductor layer in contact with the first and second contacts and lacking direct mechanical contact with the first and second metal terminals.
