Title Superconducting Single-Photon Detectors for Integrated Nanophotonics Circuits Type Conference Article
Year 2017 Publication 16th ISEC Abbreviated Journal 16th ISEC
Volume (up) Issue Pages 1-3
Keywords SSPD, SNSPD
Abstract We present an overview of our recent achievements in integration of superconducting nanowire single-photon detectors SNSPD with dielectric optical waveguides. We are able to produce complex nanophotonics integrated circuits containing optical elements and photon detector on single chip thus producing a compact integrated platform for quantum optics applications.

Title Integrated Bragg waveguides as an efficient optical notch filter on silicon nitride platform Type Conference Article
Year 2017 Publication Proc. SPBOPEN Abbreviated Journal Proc. SPBOPEN
Volume (up) Issue Pages 449-450
Keywords Bragg waveguides
Abstract We modeled and fabricated integrated optical Bragg waveguides on a silicon nitride (Si3N4) platform. Transmission spectra of the integrated notch filter has been measured and attenuation at the desired wavelength of 1550 nm down to -43 dB was observed.

Title Optimisation of spontaneous four-wave mixing in a ring microcavity Type Conference Article
Year 2017 Publication J. Phys.: Conf. Ser. Abbreviated Journal J. Phys.: Conf. Ser.
Volume (up) 47 Issue 10 Pages 887-891
Keywords ring microcavity
Abstract Abstract. A theory of spontaneous four-wave mixing in a ring microcavity is developed. The rate of emission of biphotons for pulsed and monochromatic pumping with allowance for the disper- sion of group velocities is analytically calculated. In the first case, pulses in the form of an increasing exponential are considered, which are optimal for excitation of an individual resonator mode. The behaviour of the group velocity dispersion as a function of the width and height of the waveguide is studied for a specific case of a ring microcavity made of silicon nitride. The results of the numeri- cal calculation are in good agreement with the experimental data. The ring microcavity is made of two types of waveguides: com- pletely etched and half etched. It is found that the latter allow for better control over the parameters in the manufacturing process, making them more predictable.

Title Integrated Bragg waveguides as an efficient optical notch filter on silicon nitride platform Type Conference Article
Year 2017 Publication J. Phys.: Conf. Ser. Abbreviated Journal J. Phys.: Conf. Ser.
Volume (up) 917 Issue Pages 062042
Keywords Si3N4, Bragg waveguides
Abstract We modeled and fabricated integrated optical Bragg waveguides on a silicon nitride (Si3N4) platform. These waveguides would serve as efficient notch-filters with the desired characteristics. Transmission spectra of the fabricated integrated notch filters have been measured and attenuation at the desired wavelength of 1550 nm down to -43 dB was observed. Performance of the filters has been studied depending on different parameters, such as pitch, filling factor, and height of teeth of the Bragg grating
