Paper Abstract

An InGaAs/InAlAs/InP single photon avalanche detector featuring an InAlAs Transient Carrier Buffer (TCB) layer to tentatively stop avalanche-generated electrons as a negative feedback mechanism demonstrates self-quenching and selfrecovering capabilities. The escape rate of those stopped avalanche electrons from the TCB barrier determines the recovery time and thus data rate of the detector. We show that thermionic emission and tunneling are key mechanisms in the self-recovery process. The recovery time increases with the decrease of temperature and the decrease of applied bias.
