Abstract

See full text

An apparatus comprises: a substrate; a photodetector formed on an area of a surface of the substrate; an electrical contact formed on a portion of the photodetector; and a reflector formed over a portion of the photodetector distinct from the portion of the photodetector having the electrical contact formed thereon. The substrate, the photodetector, and the reflector are arranged so that an optical signal to be detected is incident on the photodetector from within the substrate, and at least a portion of the optical signal incident on the photodetector and transmitted thereby on a first pass is reflected by the reflector to propagate through the photodetector for a second pass.
