Fiber-coupled nanowire photon counter at 1550 nm with 24% system detection efficiency

Fiber-coupled nanowire photon counter at 1550 nm with 24% system detection efficiency

We developed a fiber-coupled superconducting nanowire single-photon detector system in a close-cycled cryocooler and achieved 24% and 22% system detection efficiencies at wavelengths of 1550 and 1315 nm, respectively. The maximum dark count rate was ~1000 counts/s.
