  Title Heterodyne spectroscopy with superconducting single-photon detector Type Conference Article
  Year 2017 Publication EPJ Web Conf. Abbreviated Journal EPJ Web Conf.  
  Volume (down) 132 Issue Pages 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 Development of the experimental setup for investigation of latching of superconducting single-photon detector caused by blinding attack on the quantum key distribution system Type Conference Article
  Year 2017 Publication EPJ Web of Conferences Abbreviated Journal EPJ Web of Conferences  
  Volume (down) 132 Issue 2 Pages 2  
  Keywords  
  Abstract Recently bright-light control of the SSPD has been

demonstrated. This attack employed a “backdoor” in the detector biasing

scheme. Under bright-light illumination, SSPD becomes resistive and

remains “latched” in the resistive state even when the light is switched off.

While the SSPD is latched, Eve can simulate SSPD single-photon response

by sending strong light pulses, thus deceiving Bob. We developed the

experimental setup for investigation of a dependence on latching threshold

of SSPD on optical pulse length and peak power. By knowing latching

threshold it is possible to understand essential requirements for

development countermeasures against blinding attack on quantum key

distribution system with SSPDs.

  Title High resolution THz gas spectrometer based on semiconductor and superconductor devices Type Conference Article
  Year 2017 Publication EPJ Web Conf. Abbreviated Journal EPJ Web Conf.  
  Volume (down) 132 Issue Pages 02001 (1 to 2)  
  Keywords NbN HEB mixers, detectors, THz spectroscopy  
  Abstract The high resolution THz gas spectrometer consists of a synthesizer based on Gunn generator with a semiconductor superlattice frequency multiplier as a radiation source, and an NbN hot electron bolometer in a direct detection mode as a THz radiation receiver was presented. The possibility of application of a quantum cascade laser as a local oscillator for a heterodyne receiver which is based on an NbN hot electron bolometer mixer is shown. The ways for further developing of the THz spectroscopy were outlined.

  Title Pulsed terahertz radiation from a double-barrier resonant tunneling diode biased into self-oscillation regime Type Journal Article
  Year 2020 Publication J. Appl. Phys. Abbreviated Journal J. Appl. Phys.  
  Volume (down) 128 Issue 22 Pages 224303 (1 to 11)  
  Keywords HEB, resonant tunneling diode, RTD  
  Abstract The study of the bolometer response to terahertz (THz) radiation from a double-barrier resonant tunneling diode (RTD) biased into the negative differential conductivity region of the I–V characteristic revealed that the RTD emits two pulses in a period of intrinsic self-oscillations of current. The bolometer pulse repetition rate is a multiple of the fundamental frequency of the intrinsic self-oscillations of current. The bolometer pulses are detected at two critical points with a distance between them being half or one-third of a period of the current self-oscillations. An analysis of the current self-oscillations and the bolometer response has shown that the THz photon emission is excited when the tunneling electrons are trapped in (the first pulse) and then released from (the second pulse) miniband states.
