State of the art focal plane arrays of InP/InGaAsP Geiger-mode avalanche photodiodes for active electro-optical applications
MIT Lincoln Laboratory has developed InP/InGaAsP Geiger-Mode Avalanche Photodiodes and associated readout integrated circuits (ROICs) that have enabled numerous active optical systems over the past decade. Framed and asynchronous photon timing ROIC architectures have been demonstrated. In recent years, efforts at MITLL have focused on technology development to advance the state of the art of framed Gm APD FPAs and a 256x128 pixel FPA with on-chip data thinning has been demonstrated.
