Multi-channel SNSPD system with high detection efficiency at telecommunication wavelength
arXiv:1004.0037 · doi:10.1364/OL.35.002133
Abstract
We developed a four-channel superconducting nanowire single-photon detector system based on a Gifford-McMahon cryocooler. All channels showed a system detection efficiency (at a 100 Hz dark-count rate) higher than 16% at 1550 nm wavelength, and the best channel showed a system DE of 21% and 30% at 1550 nm and 1310 nm wavelength, respectively.
