Multi-channel SNSPD system with high detection efficiency at telecommunication wavelength

open access: yes, 2010
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 ...
