Динамика солитонов в рамках расширенного неоднородного нелинейного уравнения Шредингера c учетом нелокальности нелинейности

Purpose: Dynamics of solitons in the frame of the extended nonlinear Schrodinger equation taking into account stimulated Raman scattering in space presentation (space stimulated Raman scattering), smoothly inhomogeneous both second-order dispersion and self-phase modulation is considered. Approach: Soliton’s dynamic investigated as analytically as numerically. Findings: It is shown that wave number down shift (by space stimulated Raman scattering) is compensated with up shift (by increasing second-order dispersion or self-phase modulation). Analytical soliton solutions as a result of equilibrium of space stimulated Raman scattering and increasing both second-order dispersion and self-phase modulation is found. Regime of the dynamical equilibrium of space stimulated Raman scattering and inhomogeneous media with periodical variation of soliton's parameters is found. Analytical and numerical results for this regime are in a good agreement. Originality: The obtained results is original and can be important for optical fibers application.
