Title Superconducting quantum detector for astronomy and X-ray spectroscopy Type Conference Article

Volume Issue Pages 201-210

Abstract We propose the novel concept of ultra-sensitive energy-dispersive superconducting quantum detectors prospective for applications in astronomy and X-ray spectroscopy. Depending on the superconducting material and operation conditions, such detector may allow realizing background limited noise equivalent power 10−21 W Hz−1/2 in the terahertz range when exposed to 4-K background radiation or counting of 6-keV photon with almost 10—4 energy resolution. Planar layout and relatively simple technology favor integration of elementary detectors into a detector array.

Title Broadening of hot-spot response spectrum of superconducting NbN nanowire single-photon detector with reduced nitrogen content Type Journal Article
Year 2012 Publication Abbreviated Journal J. Appl. Phys.
Volume 112 Issue Pages
Keywords SSPD, SNSPD, magnetron sputtering, spectrum, NbN film, nitrogen concentration
Abstract The spectral detection efficiency and the dark count rate of superconducting nanowire

single-photon detectors (SNSPD) have been studied systematically on detectors made from thin

NbN films with different chemical compositions. Reduction of the nitrogen content in the 4 nm

thick NbN films results in a decrease of the dark count rates more than two orders of magnitude

and in a red shift of the cut-off wavelength of the hot-spot SNSPD response. The observed

phenomena are explained by an improvement of uniformity of NbN films that has been confirmed

by a decrease of resistivity and an increase of the ratio of the measured critical current to the

depairing current. The latter factor is considered as the most crucial for both the cut-off

wavelength and the dark count rates of SNSPD. Based on our results we propose a set of criteria

for material properties to optimize SNSPD in the infrared spectral region. VC 2012 American

Keywords SSPD, SNSPD
Abstract We present our recent results in research and development of superconducting single-photon detector (SSPD). We achieved the following performance improvement: first, we developed and characterized SSPD integrated in optical cavity and enabling its illumination from the face side, not through the substrate, second, we improved the quantum efficiency of the SSPD at around 3 μm wavelength by reduction of the strip width to 40 nm, and, finally, we improved the detection efficiency of the SSPD-based single-photon receiver system up to 20% at 1550 nm and extended its wavelength range beyond 1800 nm by the usage of the fluoride ZBLAN fibres.

Title Heating of electrons in a superconductor in the resistive state by electromagnetic radiation Type Journal Article
Year 1984 Publication Sov. Phys. JETP Abbreviated Journal Sov. Phys. JETP
Volume 59 Issue 2 Pages 442-450
Keywords Nb HEB
Abstract The effect of heating of electrons relative to phonons is observed and investigated in a superconducting film that is made resistive by current and by an external magnetic field. The effect is manifested by an increase of the film resistance under the influence of the electromagnetic radiation, and is not selective in the frequency band 10^10-10^15 Hz. The independence of the effect of frequency under conditions of strong scattering by static defects is attributed to the decisive role of electron-electron collisions in the distribution function. The experimentally obtained characteristic time of resistance variation near the superconducting transition corresponds to the relaxation time of the order parameter, while at lower temperatures and fields it corresponds to the time of the inelastic electron-phonon interaction.

Title On-chip coherent detection with quantum limited sensitivity Type Journal Article
Year 2017 Publication Sci Rep Abbreviated Journal Sci Rep
Volume 7 Issue 1 Pages 4812
Keywords waveguide, SSPD, SNSPD
Abstract While single photon detectors provide superior intensity sensitivity, spectral resolution is usually lost after the detection event. Yet for applications in low signal infrared spectroscopy recovering information about the photon's frequency contributions is essential. Here we use highly efficient waveguide integrated superconducting single-photon detectors for on-chip coherent detection. In a single nanophotonic device, we demonstrate both single-photon counting with up to 86% on-chip detection efficiency, as well as heterodyne coherent detection with spectral resolution f/f exceeding 10(11). By mixing a local oscillator with the single photon signal field, we observe frequency modulation at the intermediate frequency with ultra-low local oscillator power in the femto-Watt range. By optimizing the nanowire geometry and the working parameters of the detection scheme, we reach quantum-limited sensitivity. Our approach enables to realize matrix integrated heterodyne nanophotonic devices in the C-band wavelength range, for classical and quantum optics applications where single-photon counting as well as high spectral resolution are required simultaneously.

Abstract With use of the travelling-wave geometry approach, integrated superconductor- nanophotonic devices based on silicon nitride nanophotonic waveguide with a superconducting NbN-nanowire suited on top of the waveguide were fabricated. NbN-nanowire was operated as a single-photon counting detector with up to 92 % on-chip detection efficiency in the coherent mode, serving as a highly sensitive IR heterodyne mixer with spectral resolution (f/df) greater than 106 in C-band at 1550 nm wavelength

Title New generation of nanowire NbN superconducting single-photon detector for mid-infrared Type Journal Article
Year 2011 Publication IEEE Trans. Appl. Supercond. Abbreviated Journal IEEE Trans. Appl. Supercond.
Volume 21 Issue 3 Pages 323-326
Keywords SSPD
Abstract We present a break-through approach to mid-infrared single-photon detection based on nanowire NbN superconducting single-photon detectors (SSPD). Although SSPD became a mature technology for telecom wavelengths (1.3-1.55 μm) its further expansion to mid-infrared wavelength was hampered by low sensitivity above 2 μm. We managed to overcome this limit by reducing the nanowire width to 50 nm, while retaining high superconducting properties and connecting the wires in parallel to produce a voltage response of sufficient magnitude. The new device exhibits 10 times better quantum efficiency at 3.5 μm wavelength than the “standard” SSPD.

Title Coupling of terahertz radiation to a high-Т(с) superconducting hot electron bolometer mixer Type Journal Article
Year 1996 Publication Abbreviated Journal Appl. Phys. Lett.,
Volume 69 Issue Pages 691-693
Keywords
Abstract We report on efficient coupling of THz radiation to a high-T(c) superconducting hot electron bolometer that is suitable for heterodyne detection. Our quasioptical system consisted of a planar self-complementary spiral antenna on a dielectric substrate clamped to an extended hyperhemispherical lens. The antenna was integrated into a co-planar line for broadband intermediate frequency matching. Measurements in the homodyne regime at a frequency of 2.5 THz showed a radiation pattern with a beam width of 1° and a coupling efficiency of 0.1. We measured, at an intermediate frequency of 1.5 GHz, an output noise temperature of'160 K and estimated for the device, operated in the heterodyne regime, a system noise temperature of 30 000 K. We also discuss possibilities of significant improvement of the sensitivity.
