Superconducting nanowire single photon detector at 532 nm and demonstration in satellite laser ranging
Hao Li, Sijing Chen, Lixing You +10
Superconducting nanowire single-photon detectors (SNSPDs) at a wavelength of 532 nm were designed and fabricated aiming to satellite laser ranging (SLR) applications. The NbN SNSPD…
Nonideal optical cavity structure of superconducting nanowire single photon detector
Hao Li, Weijun Zhang, Lixing You +8
Optical cavity structure has been proven to be a crucial factor for obtaining high detection efficiency in superconducting nanowire single photon detector (SNSPD). Practically, com…
Jitter analysis of a superconducting nanowire single photon detector
Lixing You, Xiaoyan Yang, Yuhao He +9
Jitter is one of the key parameters for a superconducting nanowire single photon detector (SNSPD). Using an optimized time-correlated single photon counting system for jitter measu…
Nonlatching Superconducting Nanowire Single-Photon Detection with Quasi-Constant-Voltage Bias
Deng-Kuan Liu, Si-Jing Chen, Li-Xing You +5
Latching is a serious issue in superconducting nanowire single-photon detector (SNSPD) technology. By extensively studying the electrical transportation characteristics of SNSPD wi…
