A tunable single photon avalanche diode pixel with improved time resolution


Perimeter gated single photon avalanche diodes (PGSPAD) contain an additional terminal to prevent premature breakdown and tune the noise floor. We report a PGSPAD based pixel where reduced dead time is accomplished using simple readout electronics for a compact, area efficient readout. During the dead time of a PGSPAD, defined by the avalanche-quench-reset… (More)
