Direct measurement of the recovery time of superconducting nanowire single-photon detectors

12 Mar 2020 Autebert Claire Gras Gaëtan Amri Emna Perrenoud Matthieu Caloz Misael Zbinden Hugo Bussières Félix

One of the key properties of single-photon detectors is their recovery time, i.e. the time required for the detector to recover its nominal efficiency. In the case of superconducting nanowire single-photon detectors (SNSPDs), which can feature extremely short recovery times in free-running mode, a precise characterisation of this recovery time and its time dynamics is essential for many quantum optics or quantum communication experiments...
