Abstract
This disclosure is directed to a high-speed avalanche photodiode device configured to detect single photons. The avalanche photodiode device may include a passive quenching circuitry. The passive quenching circuitry may include a quenching resistor having a resistivity spontaneously adaptive to a bias voltage applied across the quenching resistor. Such adaptive resistivity enables a fast response time for the avalanche photodiode device when used to detect single photos in Geiger mode.
