Several important advances were reported in single-photon detectors and photon-number-resolving detectors in 2011. New materials with smaller superconducting gaps were demonstrated for superconducting nanowire single-photon detectors (SNSPDs) that le

We present a detailed characterization of the active area uniformity of InGaAs/InP Single-Photon Avalanche Diodes (SPADs) from two different design iterations. Nonuniformity of the electric field within the device active area has been measured throug

In this paper we present measurements of the normal-to superconducting phase boundary T c (H) for three different networks possessing inflation symmetry. Fluxoid quantization constraints induce the formation of a lattice of fluxoid quanta for any non

We present results for negative feedback avalanche diodes (NFADs), which are InP-based SWIR solid-state photomultipliers with single-photon sensitivity operated with just a DC bias. We demonstrate photon number resolution for a matrix of NFAD element

In this paper, we report measurements of the normal-metal-superconductor phase boundary T c (H) in disordered quasiperiodic wire networks. The initially ordered network is an eightfold quasiperiodic array of the type previously constructed by Ammann,

We report measurements of the normal-superconducting phase boundary Tc(H) for a series of square wire networks with a range of ratios for the wire widths in the two perpendicular directions. We find indirect evidence for anisotropic localization of t

We have measured the phase boundary {ital T}{sub {ital c}}({ital H}) for a series of superconducting wire networks with different types and degrees of disorder. The basic pattern to be perturbed was the square net. In the first series lines were rand

We have fabricated and studied superconducting wire networks with various geometrical properties including fractal, periodic, quasi-periodic, and random. We will discuss design and fabrication of these aluminum networks, which consist of nearly one m

We report measurements made on hybrid arrays consisting of superconducting wires along one direction of a square geometry and Josephson junctions along the perpendicular direction. The differential resistance Rd across the array as a function of norm
