Abstract

See full text

A photodetecting device is provided. The photodetecting device includes a silicon substrate, a germanium absorption region, and a plurality of microstructures. The silicon substrate includes a first surface and a second surface. The germanium absorption region is formed proximal to the first surface of the silicon substrate, and the germanium absorption region is configured to absorb photons and to generate photo-carriers. The plurality of microstructures are formed over the second surface of the silicon substrate, and the plurality of microstructures are configured to direct an optical signal towards the germanium absorption region. A system including an optical transmitter and an optical receiver is also provided.
