Our group is developing superconducting nanowire single-photon detectors (SNSPDs) for use in a variety of applications, ranging from materials characterization to fundamental tests of quantum mechanics. Our best detectors are based on tungsten silicide and typically operate at a temperature of 1 K or below. We are interested in exploring new materials for detectors that operate at higher temperatures, as well as novel refrigeration schemes for achieving low temperatures. In addition to single-element, fiber-coupled detectors, we are also developing both arrays of detectors for imaging applications and waveguide-based devices for on-chip quantum information demonstrations. We invite proposals to investigate any aspect of SNSPDs, including device design, fabrication, cryogenics, testing implementation in ultrafast and quantum optics experiments, and exploration of the underlying superconductor physics. Available resources include state-of-the-art cleanroom facilities, ultrafast lasers, high-speed electronics, and extensive infrastructure and expertise in cryogenics.
