Title Phonon cooled ultra thin NbN hot electron bolometer mixers at 620 GHz Type Conference Article
Year 1997 Publication (down) Proc. 8th Int. Symp. Space Terahertz Technol. Abbreviated Journal Proc. 8th Int. Symp. Space Terahertz Technol.
Volume Issue Pages 29-35
Keywords NbN HEB mixers
Abstract We have measured the noise performance and gain bandwidth of 35 A thin NbN hot-electron mixers integrated with spiral antennas on silicon substrate lenses at 620 GHz. A double-sideband receiver noise temperature less than 1300 K has been obtained with a 3 dB bandwidth of GHz. The gain bandwidth is 3.2 GHz. A lower noise temperature of 1100 K has been achieved with an improved set-up. The mixer output noise dominated by thermal fluctuations is about 50-60 K, and the SSB receiver and intrinsic conversion gain is about -18 and -12 dB, respectively. Without mismatch losses and excluding the loss from the beamsplitter, we expect to achieve a receiver noise temperature of less than 700 K.

Title NbN hot electron bolometric mixer for 2.5 THz: the phonon cooled version Type Conference Article
Year 1997 Publication (down) Proc. 8th Int. Symp. Space Terahertz Technol. Abbreviated Journal Proc. 8th Int. Symp. Space Terahertz Technol.
Volume Issue Pages 258-271
Keywords NbN HEB mixers
Abstract We describe an investigation of a NbN HEB mixer for 2.5 THz. NbN HEBs are phonon-cooled de-. vices which are expected, according to theory, to achieve up to 10 GHz IF conversion gain bandwidth. We have developed an antenna coupled device using a log-periodic antenna and a silicon lens. We have demon- strated that sufficient LO power can be coupled to the device in order to bring it to the optimum mixer oper- ating point. The LO power required is less than 1 microwatts as measured directly at the device. We also describe the impedance characteristics of NbN devices and compare them with theory. The experimental results agree with theory except for the imaginary part of the impedance at very low frequencies as was demonstrated by other groups.

Title Development of disordered ultra-thin superconducting vanadium nitride films Type Conference Article
Year 2019 Publication (down) Proc. 8th Int. Conf. Photonics and Information Optics Abbreviated Journal Proc. 8th Int. Conf. Photonics and Information Optics
Volume Issue Pages 425-426
Keywords VN films
Abstract We present the results of development and research of superconducting vanadium nitride VN films ~10 nm thick having different level of disorder. It is showed that both silicon substrate temperature T sub in process of magnetron sputtering and total gas pressure P affect superconducting transition temperature of sputtered films and R 300 /R 20 ratio defining their level of disorder. VN films suitable for development of superconducting single-photon detectors on their basis are obtained.

Title Characterization of topologies of superconducting photon number resolving detectors Type Conference Article
Year 2019 Publication (down) Proc. 8th Int. Conf. Photonics and Information Optics Abbreviated Journal Proc. 8th Int. Conf. Photonics and Information Optics
Volume Issue Pages 465-466
Keywords PNR SSPD
Abstract Comparative analysis for different topologies of superconducting single-photon detectors with ability to resolve up to 4 photons in a short pulse of IR radiation has been carry out. It was developed the detector with a system detection efficiency of ~ 85 % at λ = 1550 nm. The possibility of using such detector to restore photon statistics of a pulsed radiation source was demonstrated.
