Abstract
We report optical characterization of NbN nanowire superconducting single-photon detectors as a function of wavelength in the near infrared. System detection efficiency decreases from ~6 % at 1.15 υm to ~2 % at 1.72 υm, while timing jitter remains relatively constant at ~60 ps full-width-half-maximum over the range 0.7 - 2.0 υm. We further demonstrate the capabilities of this detector with time-correlated single-photon counting measurement of photoluminescence from a semiconductor sample emitting at 1.65 υm.
