    "abstract": "Superconducting single photon detectors (SSPD) based on nanopatterned niobium\nnitride wires offer single photon counting at fast rates, low jitter, and low\ndark counts, from visible wavelengths well into the infrared. We demonstrate\nthe first use of an SSPD, packaged in a commercial cryocooler, for single\nphoton source characterization. The source is an optically pumped,\nmicrocavity-coupled InGaAs quantum dot, emitting single photons on demand at\n902 nm. The SSPD replaces the second silicon Avalanche Photodiode (APD) in a\nHanbury-Brown Twiss interferometer measurement of the source second-order\ncorrelation function, g (2) (tau). The detection efficiency of the\nsuperconducting detector system is \u003e2 % (coupling losses included). The SSPD\nsystem electronics jitter is 170 ps, versus 550 ps for the APD unit, allowing\nthe source spontaneous emission lifetime to be measured with improved\nresolution.",
