Abstract

We developed an ultrahigh-sensitivity single-photon detector using a linear-mode avalanche photodiode (APD) with a cryogenic low-noise readout circuit; the APD is operated at 78 K . The noise-equivalent power of the detector is as low as 2.2 × 10 20 W / Hz 1 / 2 at a wavelength of 450 nm . The photon-detection efficiency and dark-count rate (DCR) are 0.72 and 0.0008 counts/s , respectively. A low DCR is achieved by thermal treatment for reducing the trapped carriers when the thermal treatment temperature is above 100 K .
