 Career

In 2013 I was invited to “Kazan National Research Technical University named after A.N. Tupolev – KNITU-KAI” to the Department of “Microwave-photonics and Life systems”. My goal was to enhance a scientific research and master’s degree education in part of numerical and computational modelling of physical processes in photonics, microwave technologies and live systems.

From that time, I am actively involved in scientific and teaching work, I am an effective performer of number of scientific projects, grants and programs. I am an author and lecturer of special courses: “Computing technologies of fiber-optics devices modelling”, “Computing technologies of electro dynamical and photonic processes modeling in live systems”, “Microwave photonics methods of fiber optic sensors interrogation”. I am a co-author of three study-guides for students: “The microwave photonics interrogation methods of ultra-narrow resonance structures in fiber”, “The methods and tools for monitoring of traction motors parameters using fiber-optic technologies”, “Polygarmonic sounding radiation generators with polarization multiplexing”.

Science achievements during recent five years:

Methods for direct numerical integration of a system of coupled nonlinear Schrödinger are developed. A combined explicit-implicit finite-difference integration scheme based on the Crank-Nicholson implicit finite-difference scheme has been developed, proposed and justified, which allows integrating a nonlinear system of equations with the choice of a nonlinear term at the previous integration step. An algorithm is suggested that eliminates the disadvantage associated with the determination of the nonlinear term from the previous integration step. An approach has been developed for automatic selection of the integration step, which reduces the total number of integration steps while maintaining the required accuracy of the approximate solution. A database of calculation results for some values ​​of perturbation propagation has been created. The restrictions imposed by the scheme on the length of the fiber section to be integrated are described, approaches are recommended that eliminate these restrictions without the need to increase the dimensions of the arrays of the finite-difference scheme.

The theory and technique of addressable fiber Bragg structures have been developed; a theoretical substantiation of the metrological, technical, economic and functional advantages of using addressable fiber Bragg structures in radio-photonic sensor systems is given, which differs in that an additional parameter, independent of its central wavelength, is introduced into the fiber Bragg structure – the address. The fundamentals of the theory and principles for constructing a new class of radio-photonic sensor systems based on addressable fiber Bragg structures have been developed, which make it possible to solve the problems of single- and few-sensor applications. An algorithm is proposed for determining the shift of the central wavelength of each of the structures at the output of a linear tilted optical filter and a photodetector of a low-sensor system, which makes it possible to analyze the parameters of the beat envelopes of their optical components at difference address frequencies lying in the radio range.  A mathematical model of signal processing in small and multi-sensor systems has been created, which makes it possible to solve the problem of unambiguously determining the central wavelength of each of the address structures with their single, pair and triple inclusion in various topologies under the conditions of the possible occurrence of multiple or duplicate address frequencies. Positive estimates are obtained for the possibility of implementing radio-photonic sensor systems based on addressable fiber Bragg structures, which make it possible to solve the problems of single-, few-, and multi-sensor applications.

Procedures have been developed for calibrating integrated fiber-optic sensors based on addressable fiber Bragg structures, which make it possible to determine and record their Bragg wavelengths and Lorentzian transparency windows or Gaussian reflection profiles, their bandwidths and quality factors, difference address frequencies between them, and the central wavelength of the address structure as a whole. . A theory of polyharmonic probing methods for unaddressed fiber addressable structures, used in microwave photonic sensor systems of the corresponding class, is developed, which differs in the asymmetry of the initial probing radiation. A three-frequency probing method that is asymmetric in amplitude is proposed, which makes it possible to solve all the problems of calibration indicated above. Based on the results of this research, the dissertation of the Doctor of Technical Sciences "Radiophotonic sensor systems based on addressable fiber Bragg structures and their application for solving practical problems" was defended in the specialty 05.11.07 - "Optical and Optoelectronic Devices and Complexes".
