  Title Different single-photon response of wide and narrow superconducting MoxSi1−x strips Type Journal Article
  Year 2020 Publication Phys. Rev. Applied Abbreviated Journal Phys. Rev. Applied  
  Volume 13 Issue 2 Pages (down) 024011 (1 to 7)  
  Keywords MoSi SSPD, SNSPD  
  Abstract The photon count rate (PCR) of superconducting single-photon detectors made of MoxSi1−x films shaped as a 2-μm-wide strip and a 115-nm-wide meander strip line is studied experimentally as a function of the dc biasing current at different values of the perpendicular magnetic field. For the wide strip, a crossover current Icross is observed, below which the PCR increases with an increasing magnetic field and above which it decreases. This behavior contrasts with the narrow MoxSi1−x meander, for which no crossover current is observed, thus suggesting different photon-detection mechanisms in the wide and narrow strips. Namely, we argue that in the wide strip the absorbed photon destroys superconductivity locally via the vortex-antivortex mechanism for the emergence of resistance, while in the narrow meander superconductivity is destroyed across the whole strip line, forming a hot belt. Accordingly, the different photon-detection mechanisms associated with vortices and the hot belt determine the qualitative difference in the dependence of the PCR on the magnetic field.

  Year 2019 Publication J. Phys.: Conf. Ser. Abbreviated Journal J. Phys.: Conf. Ser.  
  Volume 1410 Issue Pages (down) 012147 (1 to 5)  
  Keywords 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 Comparison single- and double- spot detection efficiencies of SSPD based to MoSi and NbN films Type Conference Article
  Year 2020 Publication J. Phys.: Conf. Ser. Abbreviated Journal J. Phys.: Conf. Ser.  
  Volume 1695 Issue Pages (down) 012146 (1 to 3)  
  Keywords NbN SSPD, SNSPD, MoSi  
  Abstract In this work, we present results of quantum detector tomography of superconducting single photon detector (SSPD) based on MoSi film, and compare them with previously reported data on NbN. We find that for both materials hot spot interaction length coincides with the strip width, and the dependence of single and double-spot detection efficiencies on bias current are compatible with sufficiently large hot-spot size, approaching the strip width.

  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 (down) 012132 (1 to 4)  
  Keywords 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 Developing of NbN films for superconducting microstrip single-photon detector Type Conference Article

  Volume 1695 Issue Pages (down) 012116 (1 to 5)  
  Keywords NbN SSPD, SNSPD, NbN films  
  Abstract We optimized NbN films on a Si substrate with a buffer SiO2 layer to produce superconducting microstrip single-photon detectors with saturated dependence of quantum efficiency (QE) versus normalized bias current. We varied thickness of films and observed the maximum QE saturation for device based on the thinner film with the lowest ratio RS300/RS20.

  Title Superconducting microstructures with high impedance Type Journal Article
  Year 2020 Publication Phys. Solid State Abbreviated Journal Phys. Solid State  
  Volume 62 Issue 9 Pages (down) 1539-1542  
  Keywords superconducting channels, SIS, inetic inductance, tunneling contacts, high impedance  
  Abstract The transport properties of two types of quasi-one-dimensional superconducting microstructures were investigated at ultra-low temperatures: the narrow channels close-packed in the shape of meander, and the chains of tunneling contacts “superconductor-insulator-superconductor.” Both types of the microstructures demonstrated high value of high-frequency impedance and-or the dynamic resistance. The study opens up potential for using of such structures as current stabilizing elements with zero dissipation.

  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 (down) 01005  
  Keywords 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 Superconducting detector for visible and near-infrared quantum emitters [Invited] Type Journal Article
  Year 2017 Publication Opt. Mater. Express Abbreviated Journal Opt. Mater. Express  
  Volume 7 Issue 2 Pages (down) 513-526  
  Keywords SSPD, SNSPD  
  Abstract Further development of quantum emitter based communication and sensing applications intrinsically depends on the availability of robust single-photon detectors. Here, we demonstrate a new generation of superconducting single-photon detectors specifically optimized for the 500–1100 nm wavelength range, which overlaps with the emission spectrum of many interesting solid-state atom-like systems, such as nitrogen-vacancy and silicon-vacancy centers in diamond. The fabricated detectors have a wide dynamic range (up to 350 million counts per second), low dark count rate (down to 0.1 counts per second), excellent jitter (62 ps), and the possibility of on-chip integration with a quantum emitter. In addition to performance characterization, we tested the detectors in real experimental conditions involving nanodiamond nitrogen-vacancy emitters enhanced by a hyperbolic metamaterial.
