Superconducting Nanowire Single Photon Detector System
Superconducting Nanowire Single Photon Detector System
The SNSPD technology originated from the superconducting single photon detection team of the Shanghai Institute of Microsystems and Information Technology, Chinese Academy of Sciences. The team has been conducting SNSPD research and development work since 2007, achieving fully independent research and development from thin film materials, device design and processing. The performance indicators of SNSPD devices in detection efficiency, dark counting, and other aspects have repeatedly set world records, and related technologies have been granted patents in China, the United States, and Japan.
