Title Resonant terahertz photoresponse and superlattice plasmons in graphene field-effect transistors Type Abstract
Year (down) 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 Development of disordered ultra-thin superconducting vanadium nitride films Type Conference Article
Year (down) 2019 Publication 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 (down) 2019 Publication 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.
