Method for Detecting Low-power Optical Signal with High Sensitivity
10 Mar 22
A method for making a pair of photodiodes to detect low-power optical signal includes providing a waveguide including one or more branches in a silicon photonics substrate to deliver an input optical signal to the silicon photonics integrated circuit; forming a pair of nearly redundant photodiodes in silicon photonics platform in the silicon photonics substrate. coupling a first one of the pair of nearly redundant photodiodes optically to each of the one or more branches for receiving the input optical signal combined from all of the one or more branches; coupling a second one of the pair of nearly redundant photodiodes electrically in series to the first one of the pair of nearly redundant photodiodes; and drawing a current from the first one of the pair of nearly redundant photodiodes under a reversed bias voltage applied to the pair of nearly redundant photodiodes.

Germanium-on-silicon Avalanche Photodetector In Silicon Photonics Platform, Method of Making the Same
3 Mar 22
A germanium-on-silicon avalanche photodetector includes a silicon device layer of a silicon-on-insulator substrate having a central region characterized by modest-heavy n+ doping state between a first electrode region and a second electrode region in heavy n++ doping state; a first sub-layer of the central region modified to nearly neutral doping state and located from a first depth down to a second depth below a top surface of the silicon device layer; a second sub-layer of the central region modified to modest p doping state embedded from the top surface down to the first depth to interface with the first sub-layer; a layer of germanium with a bottom side attached to the top surface of the second sub-layer; and a third sub-layer embedded into a top side of the layer of germanium, characterized by heavy p++ doping state.
