Abstract:
1. A waveguide photodetector comprising: a first channel waveguide extending a first length along a substrate; a second channel waveguide extending a second length along the substrate, a waveguide film disposed over a portion of the first channel waveguide, the first portion of the second channel waveguide, and the gap; a photodetector material disposed over the top region, the first side region, and the second side region of the second portion of the second channel waveguide, wherein the photodetector material forms a ridge encapsulating the second channel waveguide; and a dielectric film disposed between the second portion of the second channel waveguide and the photodetector material; the second silicon channel waveguide completely isolated from the other silicon material of the SOI substrate.
