  Title Subnanosecond photoresponse of a YBaCuO thin film to infrared and visible radiation by quasiparticle induced suppression of superconductivity Type Journal Article
  Year 1992 Publication Appl. Phys. Lett. Abbreviated Journal Appl. Phys. Lett.  
  Volume (down) 60 Issue 7 Pages 903-905  
  Keywords YBCO HTS detectors  
  Abstract We observed subnanosecond photoresponse of a structured superconducting YBa2Cu3O7−δ thin film to infrared and visible radiation. We measured the voltage response of a current biased film (thickness 700 Å) in a resistive state to radiation pulses. From our results we conclude a response time of about 90 ps and a responsivity of about 4×1010 Ω/J. We attribute the response to Cooper pair breaking and suppression of the superconducting energy gap induced by nonequilibrium quasiparticles.

  Title Semiconducting superlattice as a solid-state terahertz local oscillator for NbN hot-electron bolometer mixers Type Journal Article
  Year 2012 Publication Tech. Phys. Abbreviated Journal Tech. Phys.  
  Volume (down) 57 Issue 7 Pages 971-974  
  Keywords semiconducting superlattice frequency multiplier, NbN HEB mixers  
  Abstract We present the results of our studies of the semiconducting superlattice (SSL) frequency multiplier and its application as part of the solid state local oscillator (LO) in the terahertz heterodyne receiver based on a NbN hot-electron bolometer (HEB) mixer. We show that the SSL output power level increases as the ambient temperature is lowered to 4.2 K, the standard HEB operation temperature.

  Title Noise equivalent temperature difference of a superconducting integrated terahertz receiver Type Journal Article
  Year 2009 Publication J. Commun. Technol. Electron. Abbreviated Journal J. Commun. Technol. Electron.  
  Volume (down) 54 Issue 6 Pages 716-720  
  Keywords SIS mixer SIR NETD, FFO, harmonic mixer  
  Abstract The dependence of the noise equivalent temperature difference (NETD) of a superconducting integrated receiver (SIR) on the receiver noise temperature and the inputsignal level has been investigated. An unprecedented NETD of 13±2 mK has been measured at a SIR noise temperature of 200 K, intermediate-frequency bandwidth of 4 GHz, and time constant of 1 s. With a decrease in the input signal, an improvement in the NETD is observed. This effect is explained by a reduction in the influence of the instabilities of the receiver power supply and the amplification circuit that occur when the input signal is decreased.

  Title Long-distance fiber-optic quantum key distribution using superconducting detectors Type Conference Article
  Year 2015 Publication Proc. Optoelectron. Instrum. Abbreviated Journal Proc. Optoelectron. Instrum.  
  Volume (down) 51 Issue 6 Pages 548-552  
  Keywords QKD, SSPD, SNSPD  
  Abstract This paper presents the results of experimental studies on quantum key distribution in optical fiber using superconducting detectors. Key generation was obtained on an experimental setup based on a self-compensation optical circuit with an optical fiber length of 101.1 km. It was first shown that photon polarization encoding can be used for quantum key distribution in optical fiber over a distance in excess of 300 km.

  Title Determination of dielectric properties of ore minerals in the microwave band Type Journal Article
  Year 2008 Publication Radiophys. Quant. Electron. Abbreviated Journal Radiophys. Quant. Electron.  
  Volume (down) 51 Issue 12 Pages 966-974  
  Keywords ore complex permittivity, chalcopyrite, magnetite, sphalerite, labradorite  
  Abstract We consider a method for determining the complex dielectric permittivity of ore and nonmetal minerals in the microwave band of electromagnetic radiation. The results of measuring the reflectivity and transmittivity of chalcopyrite, magnetite, sphalerite, and labradorite samples in the frequency range 77–300 GHz are presented. A method for calculation of the complex dielectric permittivity of minerals on the basis of the obtained experimental data is proposed. The approximation formulas for calculation of the complex dielectric permittivity of the studied minerals are given.
