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 (up) 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 Gate-mediated helicity sensitive detectors of terahertz radiation with graphene-based field effect transistors Type Abstract
Year 2020 Publication Graphene and 2dm Virt. Conf. Abbreviated Journal Graphene and 2DM Virt. Conf.
Volume (up) Issue Pages
Keywords single layer graphene, SLG, CVD, plasmons, FET
Abstract Closing of the so-called terahertz gap results in an increased demand for optoelectronic devices operating in the frequency range from 0.1 to 10 THz. Active plasmonic in field effect devices based on high-mobility two-dimensional electron gas (2DEG) opens up opportunities for creation of on-chip spectrum [1] and polarization [2] analysers. Here we show that single layer graphene (SLG) grown using CVD method can be used for an all-electric helicity sensitive polarization broad analyser of THz radiation. Allourresults show plasmonic nature of response. Devices are made in a configuration ofa field-effect transistor (FET) with a graphene channel that has a length of 2 mkm and a width of 5.5 mkm. Response of opposite polarity to clockwise and anticlockwise polarized radiation is due to special antenna design (see Fig.1c) as follow works [2,3]. Our approaches can be extrapolated to other 2D materials and used as a tool to characterize plasmonic excitations in them. [1]Bandurin, D.

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 (up) 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 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 (up) 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 Ag2S QDs/Si heterostructure-based ultrasensitive SWIR range detector Type Journal Article
Year 2020 Publication Nanomaterials (Basel) Abbreviated Journal Nanomaterials (Basel)
Volume (up) 10 Issue 5 Pages 1-12
Keywords detector; quantum dots; short-wave infrared range; silicon
Abstract In the 20(th) century, microelectronics was revolutionized by silicon-its semiconducting properties finally made it possible to reduce the size of electronic components to a few nanometers. The ability to control the semiconducting properties of Si on the nanometer scale promises a breakthrough in the development of Si-based technologies. In this paper, we present the results of our experimental studies of the photovoltaic effect in Ag2S QD/Si heterostructures in the short-wave infrared range. At room temperature, the Ag2S/Si heterostructures offer a noise-equivalent power of 1.1 x 10(-10) W/ radicalHz. The spectral analysis of the photoresponse of the Ag2S/Si heterostructures has made it possible to identify two main mechanisms behind it: the absorption of IR radiation by defects in the crystalline structure of the Ag2S QDs or by quantum QD-induced surface states in Si. This study has demonstrated an effective and low-cost way to create a sensitive room temperature SWIR photodetector which would be compatible with the Si complementary metal oxide semiconductor technology.
