Abstract:
A resonant photodetector assembly comprising:a substrate;a photodetector positioned on the substrate, said photodetector having a plurality of generally planar semiconductor layers including a photodetector active layer where light is converted into an electrical output, said photodetector including a first electrical contact layer and a second electrical contact layer; anda waveguide positioned on said substrate and adjacent to the photodetector, said waveguide having a waveguide active layer positioned between a pair of waveguide cladding layers, said waveguide including a first end for receiving said light and a second end for directing said light to the photodetector; anda first reflector for reflecting the light from the waveguide, said first reflector being positioned on a side of the photodetector opposite to the waveguide so that the light from the waveguide travels through the photodetector active layer before being reflected by the first reflector.
