About
I work actively in the theory of dissipative solitons and nonlinear dynamics of dissipative systems. The extensive numerical simulations of underlying nonlinear deterministic and stochastic PDEs revealed different dissipative soliton chaotization and destabilization scenarios, including turbulent and rogue wave regimes. The numerical simulations were connected closely with the analytical approaches such as adiabatic and variational integration techniques and a method of moments. The adiabatic integration technique developed by me allowed the reconstruction of the dissipative solitons parametric space (dissipative soliton “master diagram”). The structure of parametric space allowed the formulation of the analytical laws of dissipative soliton energy scaling (harvesting), optical turbulence, temporal thermalization, and spectral condensation. This approach was used to develop state-of-the-art laser technology, providing femtosecond pulse energy scalability. The fundamental limitations on the soliton energy scalability imposed by quantum noise were revealed. As a result, the issue of soliton quantization was raised. The study of soliton interactions with photon and phonon quantum basins revealed new regimes of soliton chaotization and the existence of a new type of dissipative soliton, the so-called Raman dissipative soliton. The issue of quantum properties of nonlinear dissipative systems were studied in the frameworks of the phase-space (Weyl-Wigner) and Langevin representations of quantum phenomenology. The analytical approaches to soliton quantization based on perturbation theory were developed.
The concept of solitonic spectroscopy was developed. It was shown that the spectral sensitivity could be enhanced substantially, especially for a dissipative soliton that could provide realizing micro-chip laser devices for environment sensing.
I was actively involved in the analysis of supercontinuum. The models for stimulated Raman scattering, high-order dispersions, noises, and mode composition of real-world microstructured fibers have been developed and verified experimentally. The statistical properties, coherence, and structure of supercontinuum and high-harmonic generation in bulk material and a fiber supercontinuum were analyzed and interpreted. The space-time dynamics of supercontinuum was investigated in the multimode fiber structures. The models of spectral extra-broadening and “multi-color” generation in both solid-state and fiber mode-locked lasers were developed.
Currently, I am involved in the theoretical study of the nonlinear spatio-temporal dynamics of femtosecond pulses in fibers and bulk materials, including their impact on material modification and microstructure formation. The principal new mechanism of so-called distributed Kerr-lens mode-locking in solid-state and fiber lasers is demonstrated. This mechanism based on the ideas of higher-order mode synthesizing and cleaning enhanced by dissipation provides tools for unprecedented energy harvesting by femtosecond pulses in multi-mode fibers and multichannel amplification systems. Simultaneously, the existence of stable spatio-temporal solitons stabilized by a graded dissipation was conjectured.
I numerically investigated the impact of different nonlinear effects, including plasma formation on the modification of bulk materials (e.g., Si). The strong contribution of nonlinear spherical aberrations and wavelength dependence of modification mechanisms was demonstrated for the mid-IR femtosecond pulses. That could allow the fabrication of different types of micro-resonators and waveguides.
I demonstrated the stabilization of two-dimensional nonlinear wave patterns theoretically using a dissipative confinement potential. That shows a close analogy between a weakly-dissipative Bose-Einstein condensate dynamics and a mode-locked multimode fiber laser operating in the anomalous dispersion regime. Here, I suggest that the close analogy between nonlinear phenomena in atomic and photonic systems makes the latter an ideal testbed for exploring fundamental physics, ranging from plasma to Bose-Einstein condensate.
