We report a system detection efficiency of 55 % at 1500 nm with an amorphous tungsten-silicide (WSi) superconducting nanowire single-photon detector (SNSPD) using a self-aligned packaging scheme for alignment of the detector and optical fiber.

High-efficiency WSi superconducting nanowire single-photon detectors operating at 2.5 K

V. B. Verma, Boris A. Korzh, Félix Bussières +7 more

We investigate the operation of WSi superconducting nanowire single-photon detectors (SNSPDs) at 2.5 K, a temperature which is ∼70% of the superconducting transition temperature (TC) of 3.4 K. We demonstrate saturation of the system detection efficiency at 78 ± 2% at a wavelength of 1310 nm, with a jitter of 191 ps. We find that the jitter at 2.5 K is limited by the noise of the readout and can be improved through the use of cryogenic amplifiers. Operation of SNSPDs with high efficiency at temperatures very close to TC appears to be a unique property of amorphous WSi.
