  Title Enhance of the superconducting properties of the NbN/Au bilayer bridges Type Conference Article
  Year 2020 Publication J. Phys.: Conf. Ser. Abbreviated Journal J. Phys.: Conf. Ser.  
  Volume 1695 Issue Pages 012132 (1 to 4)  
  Keywords (down) SSPD, SNSPD  
  Abstract We experimentally demonstrate strong temperature dependence of the critical current of the superconducting 600-nm-wide and 5-μm-long bridge made of NbN/Au bilayer. The result is achieved due to the proximity effect realized between the highly disordered superconducting NbN layer and low resistive normal-metal Au layer.

  Title Superconducting photon counter for nanophotonics applications Type Conference Article
  Year 2019 Publication J. Phys.: Conf. Ser. Abbreviated Journal J. Phys.: Conf. Ser.  
  Volume 1410 Issue Pages 012147 (1 to 5)  
  Keywords (down) SSPD, SNSPD  
  Abstract We develop large area superconducting single-photon detector SSPD with a micron-wide strip suitable for free-space coupling or packaging with multi-mode optical fibres. The detector sensitive area is 20 μm in diameter. In near infrared (1330 nm wavelength) our SSPD exhibits above 30% detection efficiency with low dark counts and 45 ps timing jitter.

  Title Vortex-assisted mechanism of photon counting in a superconducting nanowire single-photon detector revealed by external magnetic field Type Journal Article
  Year 2015 Publication Phys. Rev. B Abbreviated Journal Phys. Rev. B  
  Volume 92 Issue 10 Pages 104503 (1 to 9)  
  Keywords (down) SSPD, SNSPD  
  Abstract We use an external magnetic field to probe the detection mechanism of a superconducting nanowire single-photon detector. We argue that the hot belt model (which assumes partial suppression of the superconducting order parameter Δ across the whole width of the superconducting nanowire after absorption of the photon) does not explain observed weak-field dependence of the photon count rate (PCR) for photons with λ=450nm and noticeable decrease of PCR (with increasing the magnetic field) in a range of the currents for photons with wavelengths λ=450–1200nm. Found experimental results for all studied wavelengths can be explained by the vortex hot spot model (which assumes partial suppression of Δ in the area with size smaller than the width of the nanowire) if one takes into account nucleation and entrance of the vortices to the photon induced hot spot and their pinning by the hot spot with relatively large size and strongly suppressed Δ.

  Title High speed infrared photon counting with photon number resolving superconducting single-photon detectors (SSPDs) Type Conference Article
  Year 2009 Publication CLEO/Europe – EQEC Abbreviated Journal CLEO/Europe – EQEC  
  Volume Issue Pages  
  Keywords (down) SSPD, SNSPD  
  Abstract A review of development and characterization of the nanostructures consisting of several meander sections, all connected in parallel was presented. Such geometry leads to a significant decrease of the kinetic inductance, without a decrease of the SSPD active area. A new type of SSPDs possess the QE of large-active- area devices, but, simultaneously, allows achieving short response times and the GHz-counting rate. This new generation of superconducting detectors has another significant advantage for quantum key distribution, they have a photon number resolving capability and can distinguish more photons.

  Title Submicron axial resolution in an ultrabroadband two-photon interferometer using superconducting single-photon detectors Type Journal Article
  Year 2008 Publication Opt. Express Abbreviated Journal Opt. Express  
  Volume 16 Issue 19 Pages 15104-15108  
  Keywords (down) SSPD, SNSPD  
  Abstract We generate ultrabroadband biphotons via the process of spontaneous parametric down-conversion in a quasi-phase-matched nonlinear grating that has a linearly chirped poling period. Using these biphotons in conjunction with superconducting single-photon detectors (SSPDs), we measure the narrowest Hong-Ou-Mandel dip to date in a two-photon interferometer, having a full width at half maximum (FWHM) of approximately 5.7 fsec. This FWHM corresponds to a quantum optical coherence tomography (QOCT) axial resolution of 0.85 µm. Our results indicate that a high flux of nonoverlapping biphotons may be generated, as required in many applications of nonclassical light.

  Title Investigating the detection regimes of a superconducting single-photon detector Type Journal Article
  Year 2013 Publication J. Opt. Technol. Abbreviated Journal J. Opt. Technol.  
  Volume 80 Issue 7 Pages 435  
  Keywords (down) SSPD, quantum efficiency  
  Abstract The detection regimes of a superconducting single-photon detector have been investigated. A technique is proposed for determining the regions in which “pure regimes” predominate. Based on experimental data, the dependences of the internal quantum efficiency on the bias current are determined in the one-, two-, and three-photon detection regimes.

  Title Heterodyne spectroscopy with superconducting single-photon detector Type Conference Article
  Year 2017 Publication EPJ Web Conf. Abbreviated Journal EPJ Web Conf.  
  Volume 132 Issue Pages 01005  
  Keywords (down) SSPD mixer, SNSPD  
  Abstract We demonstrate successful operation of a Superconducting Single Photon Detector (SSPD) as the core element in a heterodyne receiver. Irradiating the SSPD by both a local oscillator power and signal power simultaneously, we observed beat signal at the intermediate frequency of a few MHz. Gain bandwidth was found to coincide with the detector single pulse width, where the latter depends on the detector kinetic inductance, determined by the superconducting nanowire length.

  Title Sub-shot-noise-limited fiber-optic quantum receiver Type Journal Article
  Year 2020 Publication Phys. Rev. A Abbreviated Journal Phys. Rev. A  
  Volume 101 Issue 3 Pages 032306 (1 to 5)  
  Keywords (down) SSPD mixer, SNSPD  
  Abstract We experimentally demonstrate a quantum receiver based on the Kennedy scheme for discrimination between two phase-modulated weak coherent states. The receiver is assembled entirely from standard fiber-optic elements and operates at a conventional telecom wavelength of 1.55 μm. The local oscillator and the signal are transmitted through different optical fibers, and the displaced signal is measured with a high-efficiency superconducting nanowire single-photon detector. We show the discrimination error rate is two times below that of a shot-noise-limited receiver with the same system detection efficiency.

  Title Optical single photon detection in micron-scaled NbN bridges Type Miscellaneous
  Year 2018 Publication arXiv Abbreviated Journal  
  Volume Issue Pages  
  Keywords (down) SSPD  
  Abstract We demonstrate experimentally that single photon detection can be achieved in micron-wide NbN bridges, with widths ranging from 0.53 μm to 5.15 μm and for photon-wavelengths from 408 nm to 1550 nm. The microbridges are biased with a dc current close to the experimental critical current, which is estimated to be about 50 % of the theoretically expected depairing current. These results offer an alternative to the standard superconducting single-photon detectors (SSPDs), based on nanometer scale nanowires implemented in a long meandering structure. The results are consistent with improved theoretical modelling based on the theory of non-equilibrium superconductivity including the vortex-assisted mechanism of initial dissipation.
