Title The cascade switching of the photon number resolving superconducting single-photon detectors Type (down) Journal Article
Year 2021 Publication IEEE Trans. Appl. Supercond. Abbreviated Journal IEEE Trans. Appl. Supercond.
Volume 31 Issue 2 Pages 1-4
Keywords PNR SSPD, SNSPD
Abstract In this article, present the first detailed study of cascade switching in superconducting photon number resolving detectors. The detectors were made in the form of four parallel nanowires, coupled with the single-mode optical fiber and mounted into a closed-cycle refrigerator with a temperature of 2.1 K. We found out the value of additional false pulses (N cas.sw. ) appearing due to cascade switching and showed that it is possible to set up the detector bias current that corresponds to a high level of the detection efficiency and a low level of N cas.sw. simultaneously. We reached the detection efficiency of 60% and N cas.sw. = 0.3%.

Title Development of A Silicon Membrane-based Multi-pixel Hot Electron Bolometer Receiver Type (down) Conference Article
Year 2017 Publication IEEE Trans. Appl. Supercond. Abbreviated Journal IEEE Trans. Appl. Supercond.
Volume 27 Issue 4 Pages 6
Keywords Multi-pixel, HEB, silicon-on-insulator, horn array
Abstract We report on the development of a multi-pixel

Hot Electron Bolometer (HEB) receiver fabricated using

silicon membrane technology. The receiver comprises a

2 × 2 array of four HEB mixers, fabricated on a single

chip. The HEB mixer chip is based on a superconducting

NbN thin film deposited on top of the silicon-on-insulator

(SOI) substrate. The thicknesses of the device layer and

handling layer of the SOI substrate are 20 μm and 300 μm

respectively. The thickness of the device layer is chosen

such that it corresponds to a quarter-wave in silicon at

1.35 THz. The HEB mixer is integrated with a bow-tie

antenna structure, in turn designed for coupling to a

circular waveguide,

Title Development of terahertz superconducting hot-electron bolometer mixers Type (down) Conference Article
Year 2003 Publication Proc. 6th European Conf. Appl. Supercond. Abbreviated Journal Proc. 6th European Conf. Appl. Supercond.
Volume 181 Issue Pages 2960-2965
Keywords NbN HEB mixers
Abstract We present recent results of the development of phonon cooled hot-electron bolometric (HEB) mixers for airborne and balloon borne terahertz heterodyne receivers. Three iomportant issues have been addresses: the quality of NbN films the HEB mixers were made from, the spectral properties of the HEB mixers and the local oscillator power required for optical operation. Studies with an atomic force microscope indicate, that the performance of the HEB mixer might have been effected by the microstructure of the NbN film. Antenna gain and noise temperature were investigated at terahertz frequencies for a HEB embedded in either log-spiral or twin-slot feed antenna. Comparison suggests that at frequencies above 3 THz the spiral feed provides better overall performance. At 1.6 THz, a power of 2.5 µW was required from the local oscillator for optimal operation of the HEB mixer.

Title Transparency of YBCO film/substrate interfaces for thermal phonons determined by photoresponse measurements Type (down) Conference Article
Year 1993 Publication Proc. 1st European Conf. on Appl. Supercond. Abbreviated Journal Proc. 1st European Conf. on Appl. Supercond.
Volume 2 Issue Pages 1443-1446
Keywords YBCO HTS detectors
Abstract Direct measurements of the thermal boundary resistance were performed by means of the stationary method. In this approach the temperature of an electrically heated film is controlled by its dc resistance while an additional film on the same substrate is used as a thermometer monitoring substrate temperature. The temperature field in the substrate is then calculated to deduce the Kapitza temperature step at the interface between the heated strip and the substrate. The main statement of all afore-said papers is that experimental values of the thermal boundary resistance are too large to be explained by the acoustic mismatch model. In this paper we investigate transparency of YBaCuO film/substrate interfaces for thermal phonons by means of photoresponse measurements. We show that our data are in reasonable agreement with the acoustic mismatch theory.
