During last two decades I have been working on various problems of nonlinear science, including soliton theory, self-focusing of light beams, discrete nonlinear systems, and nonlinear fibre optics. My recent research has been shifted towards the high-speed optical communications, nonlinear photonic devices, Raman-based technologies, and ultra-long fibre lasers. Since 2005, I hold the Royal Society Wolfson Research Merit Award.
Research interests in nonlinear science:
Dynamics of nonlinear waves and solitons, stability of nonlinear waves, propagation of nonlinear waves in optical fibres; theory of the pulse generation and amplification in active media; dynamics of the coherent structures in lattices including waveguide and fibre arrays; energy localization in lattices; supercontinuum generation in fibres.
Fibre optic and optical communications:
High-bit-rate optical communication systems, dispersion-management in fibre transmission lines; soliton-based transmission and optical signal processing lines, design and modelling of advanced components and devices for high-bit-rate optical communication systems, statistics of nonlinear optical data transmission, information theory of nonlinear fibre channels, all-optical regeneration; fibre laser technologies, including ultra-long fibre lasers, modelling and design of fibre lasers and converters; Raman-based amplification in high-speed fibre links.
