Abstract:
A method for fabricating a resonant photodetector assembly, comprising:forming a semiconductor supporting structure, including a substrate; forming a semiconductor reflector layer on said semiconductor supporting structure; forming a combination of generally planar semiconductor layers on said semiconductor reflector layer; forming a plurality of waveguide layers on said combination of generally planar semiconductor layers; forming a photodetector active layer from said combination of generally planar semiconductor layers, the photodetector active layer being operable to convert light into an electrical output; forming a waveguide from the plurality of waveguide layers, the waveguide having a first end to receive light and a second end for directing the light to the photodetector active layer; and forming a waveguide reflector layer on the second end of the waveguide, the waveguide reflector layer being positioned so that light traveling through the waveguide is directed towards the photodetector active layer.
