  Title Resonant terahertz photoresponse and superlattice plasmons in graphene field-effect transistors Type Abstract
  Year 2019 Publication APS March Meeting Abbreviated Journal APS March Meeting  
  Volume Issue Pages F14.015  
  Keywords  
  Abstract Plasmons, collective oscillations of electron systems, can couple light and electric current, and thus can be used to create compact photodetectors, radiation mixers, and spectrometers. Despite the effort, it has proven challenging to implement plasmonic devices operating at THz frequencies. The material capable to meet this challenge is graphene as it supports long-lived electrically-tunable plasmons. In this talk, we will demonstrate plasmon-assisted resonant detection of THz radiation by antenna-coupled graphene FETs that act as both rectifying elements and plasmonic Fabry-Perot cavities amplifying the photoresponse. We will show that by varying the plasmon velocity using gate voltage, our detectors can be tuned between multiple resonant modes, a functionality that we apply to measure plasmons' wavelength and lifetime in graphene as well as to probe collective modes in its moire minibands. Our approach offers a convenient tool for further plasmonic research that is often difficult under non-ambient conditions and promises a viable route for various THz applications.

  Title Transition-edge sensors based on superconducting nanowires Type Abstract
  Year 2006 Publication Proc. APS March Meeting Abbreviated Journal Proc. APS March Meeting  
  Volume Issue Pages B38.00001  
  Keywords NbN nanowire TES  
  Abstract We present our experimental study of superconducting NbN nanowire-based sensor. The responsivity of the sensor is strongly affected by the superconducting transition width of the nanostructure, which, in turn, is determined by the phase slip centers (PCSs) dynamics. The fluctuations and noise properties of the sensor are also discussed, as well as the devices' behavior at high magnetic fields. The ultimate performance of the sensor and prospects of the devices will be discussed, as well.

  Title Photon-number-resolution with sub-30-ps timing using multi-element superconducting nanowire single photon detectors Type Journal Article
  Year 2009 Publication J. Modern Opt. Abbreviated Journal J. Modern Opt.  
  Volume 56 Issue 2 Pages 364-373  
  Keywords PNR SSPD; SNSPD; photon-number-resolution; superconducting nanowire single photon detector; timing jitter; system detection efficiency  
  Abstract A photon-number-resolving detector based on a four-element superconducting nanowire single photon detector is demonstrated to have sub-30-ps resolution in measuring the arrival time of individual photons. This detector can be used to characterize the photon statistics of non-pulsed light sources and to mitigate dead-time effects in high-speed photon counting applications. Furthermore, a 25% system detection efficiency at 1550 nm was demonstrated, making the detector useful for both low-flux source characterization and high-speed photon-counting and quantum communication applications. The design, fabrication and testing of this detector are described, and a comparison between the measured and theoretical performance is presented.

  Title Integrated contra-directional coupler for NV-centers photon filtering Type Conference Article

  Volume Issue Pages 354-360  
  Keywords NV-centers, nanodiamonds, quantum photonic integrated circuits, contra-direction coupler, Bragg gratings  
  Abstract We modelled an integrated optical contra-directional coupler on silicon nitride platform. Performance of the filter was studied depending on different parameters, including the grating period and the height of teeth of the Bragg grating near 637 nm operation wavelength. The obtained results can be used for a design and fabrication of quantum photonic integrated circuits with on-chip single-photon NV-centers in nanodiamonds.

  Volume Issue Pages 344-348  
  Keywords  
  Abstract The development of integrated quantum photonics requires a high efficient excitation and coupling of a single photon source with on-chip devices. In this paper, we show our results of modelling for high-Q photonic crystal cavity, optimized for zero phonon line emission of NV-centers in nanodiamonds. Modelling was performed for the silicon nitride platform and obtained a quality factor equals to 6136 at 637 nm wavelength.

  Title Development and applications of terahertz hot electron bolometers Type Abstract
  Year 2021 Publication 1st Moscow Int. Conf. on Submillimeter and Millimeter Astronomy: Objectives and Instruments Abbreviated Journal 1st Moscow Int. Conf. on Submillimeter and Millimeter Astronomy: Objectives and Instruments  
  Volume Issue Pages  
  Keywords  
  Abstract The development of techniques and technologies for the deposition of ultrathin superconducting films, the creation of superconducting structures on a nanometer scale is the basis of significant progress in the field of superconducting receiving systems. Ultrathin NbN films are the basis for a wide range of record-breaking hot electron devices: direct and heterodyne terahertz detectors. Terahertz receivers are especially in demand in high-resolution spectroscopy for astronomical, atmospheric, and medical research. HEB receivers are widely used in terahertz radio astronomy. For example, the Dutch SRON Institute is preparing a project for the GUSTO hot air balloon telescope with a HEB mixer array at 1.4 THz and 1.9 THz. A 5-meter Chinese terahertz telescope DATE5 with HEB mixers at 1.4 THz is installed at the South Pole. The Stratospheric Observatory (SOFIA) uses HEB mixer matrices in the GREAT instrument operating in the 1.2 – 4.7 THz range. It is planned to implement the international project Origins Space Telescope (OST) in the far infrared region based on HEB receivers. The Japanese project Smiles-2 will allow measurements at 1.8 THz in the upper layers of the stratosphere and mesosphere. The development of the Millimetron space observatory continues in Russia.

  Title Comparison of hot-spot formation in NbN and MoN thin superconducting films after photon absorption Type Conference Article
  Year 2017 Publication IEEE Transactions on Applied Superconductivity Abbreviated Journal IEEE Transactions on Applied Superconductiv  
  Volume 27 Issue 4 Pages 5  
  Keywords Thin film devices, Superconducitng photoncounting devices, Nanowire single-photon detectors  
  Abstract In superconducting single-photon detectors SSPD

the efficiency of local suppression of superconductivity and hotspot

formation is controlled by diffusivity and electron-phonon

interaction time. Here we selected a material, 3.6-nm-thick MoNx

film, which features diffusivity close to those of NbN traditionally

used for SSPD fabrication, but with electron-phonon interaction

time an order of magnitude larger. In MoNx detectors we study

the dependence of detection efficiency on bias current, photon

energy, and strip width and compare it with NbN SSPD. We

observe non-linear current-energy dependence in MoNx SSPD

and more pronounced plateaus in dependences of detection

efficiency on bias current which we attribute to longer electronphonon

interaction time.

  Volume Issue Pages 349-353  
  Keywords NV-centers, focusing grating coupler  
  Abstract Here we presented the numerical results for the calculation of focusing grating coupler efficiency in the visible wavelength range. Using the finite element method, the optimal geometric parameters, including filling factor and grating period for a central wavelength of 637 nm, were found. Obtained results allow to input/output single-photon radiation from NV-centers, and can be used for research and development of a scalable on-chip quantum optical computing.
