  ABSTRACT: We experimentally map the transverse profile of diffractionlimited beams using photon-number-resolving detectors.We observe strong compression of diffracted beam profiles for high detected photon number. This effect leads to higher contrast than a conventional irradiance profile between two Airy disk-beams separated by the Rayleigh criterion.

  ABSTRACT: We analyze the generation of single spatial mode, spectrally uncorrelated photon pairs via type II spontaneous parametric down-conversion in a Potassium Titanyl Phosphate (KTP) waveguide using real experimental parameters. We show that this source can be used as an efficient, heralded, pure-state single-photon source.

  ABSTRACT: We report the development of a fiber-based single-spatial-mode source of photon-pairs where the efficiency of extracting photon-pairs is improved over a previous source [18] through the use of fiber-end expansion and Bragg filters. This improvement in efficiency enabled a spectrally bright and pure photon-pair source having a small second-order correlation func-tion (0.03) and a raw spectral brightness of 44,700 pairs s −1 nm −1 mW −1 . The source can be configured to generate entangled photon-pairs, character-ized via optimal and minimal quantum state tomography, to have a fidelity of 97% and tangle of 92%, without subtracting any background., "A versatile waveguide source of photon pairs for chip-scale quantum information processing," Opt.
