Abstract
A photodetector having a light transmissive and electrical conducting spacer layer interposed between a semiconductor body having a semiconductor junction therein and a light reflective electrical contact to the body. The spacer layer may have a thickness of about one-half the wavelength of light passing through the body and impinging on the spacer layer or the thicknesses of the spacer layer and the active body may be so adjusted that the reflectivity of the photodetector at a particular wavelength is reduced.
