Photon-Counting Digital Focal Plane Array: FY19 Optical Systems Technology Line-Supported Program

Abstract

Visible imagers based on charge-coupled devices (CCDs) can be produced with large format and high pixel yield but typically operate at frame rates of a few Hz. For higher frame rate operation in photon-starved operation, arrays of Geiger-mode avalanche photodiodes (GmAPDs) operating in photon-counting mode are more attractive. To date, GmAPD arrays have been limited to modest formats (e.g., 256256).Scaling to larger formats involves solving challenges in the GmAPD focal plane array (FPA), the readout integrated circuit (ROIC), the hybridization, and the packaging. One of the key challenges is developing aROIC architecture that interfaces with GmAPDs and provides required power distribution to the APDs aswell as internal to the ROIC and is capable of high data rates (10s of Gb/s).
