Time-correlated single-photon counting with superconducting single-photon detectors



Martin Stevens, Robert Hadfield, Robert E. Schwall, Sae Woo Nam, Richard Mirin


We report use of a niobium nitride superconducting single-photon detector in a time-correlated single-photon counting experiment. The detector has a timing jitter of 68 +/- 3 ps full-width at half-maximum with a Gaussian temporal profile. The detector's dark count rate and detection efficiency can be tuned by adjusting the bias current applied to the device. Typical values include a detection efficiency of 1-2% and a dark count rate below 100 Hz. We use this detector to measure time-resolved photoluminescence at wavelengths up to 1650 nm, well beyond the range of conventional silicon detectors. We also use this superconducting detector to measure the emission of a quantum dot single-photon source.
