Title Picosecond response of YBaCuO films to electromagnetic radiation Type Conference Article
Year 1990 Publication Proc. European Conf. High-Tc Thin Films and Single Crystals Abbreviated Journal Proc. European Conf. High-Tc Thin Films and Single Crystals
Volume Issue Pages 457-462
Keywords YBCO HTS detectors
Abstract Radiation-induced change of the resistance was studied in the resistive state of YBaCuO films. Electron-phonon relaxation time T h was determmed from direct ep measurements and analysis of quasistationary electron heating. Temperature dependence of That TS 40 K was found to – ep be T h.. T'. The resul ts show that ep detectors with the response time of few picosecond at nitrogen temperature can be realized.

Title Waveguide integrated superconducting single-photon detector for on-chip quantum and spectral photonic application Type Conference Article
Year 2017 Publication J. Phys.: Conf. Ser. Abbreviated Journal J. Phys.: Conf. Ser.
Volume 917 Issue Pages 062032
Keywords SSPD, SNSPD, waveguide
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 Integrated contra-directional coupler for NV-centers photon filtering Type Conference Article
Year 2020 Publication Proc. 32-nd EMSS Abbreviated Journal Proc. 32-nd EMSS
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.

Title Silicon nitride focusing grating coupler for input and output light of NV-centers Type Conference Article
Year 2020 Publication Proc. 32-nd EMSS Abbreviated Journal Proc. 32-nd EMSS
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.

Title Silicon nitride photonic crystal cavity coupled with NV-centers in nanodiamonds Type Conference Article
Year 2020 Publication Proc. 32-nd EMSS Abbreviated Journal Proc. 32-nd EMSS
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.
