Claim:
1. A photodetector, comprising: a substrate including a device layer on a surface thereof; a first doped semiconductor contact supported by the device layer; a second doped semiconductor contact on the device layer; an intrinsic semiconductor body, comprising germanium, in electrical contact with the first doped semiconductor contact and the second doped semiconductor contact, the intrinsic semiconductor body capable of generating electrical signals by absorbing electromagnetic radiation; a first metal terminal, in electrical communication with said first doped semiconductor contact, but lacking direct contact with the intrinsic semiconductor body; and a second metal terminal, in electrical communication with said second doped semiconductor contact, but lacking direct contact with the intrinsic semiconductor body; wherein the first and second metal terminals are configured to provide the electrical signals to external circuitry.
