In this article, a fiber-coupled single-photon detection system using amorphous tungsten silicide superconducting nanowire detectors was developed, and the system detection efficiency was higher than 90% in the wavelength range between 1520 nm and 1610 nm.Abstract:
Researchers develop a fiber-coupled single-photon-detection system using amorphous tungsten silicide superconducting nanowire single-photon detectors. The system detection efficiency is higher than 90% in the wavelength range between 1520 nm and 1610 nm. The device dark-count rate, timing jitter and reset time are 1 cps, 150 ps and 40 ns, respectively.read more
