Взаимодействие коротких однокомпонентных векторных солитонов

Interaction of single-component different-polarization vector solitons of the enveloping function in anisotropic media is studied within the framework of the system of two coupled third-order nonlinear Schrödinger equations which allow for the third-order linear dispersion, nonlinear dispersion, crossed nonlinear phase modulation, and crossed nonlinear dispersion. The regimes of mutual reflection, passing, and asymptotic approaching of the solitons are obtained. It is shown that the character of interaction of such solitons is determined by the initial relationship among both their amplitudes and phases. The stationary mutual locations of interacting solitons and their coupled, the so-called breather states are discussed. The roles of the cubic nonlinearity, crossed cubic nonlinearity, and crossed nonlinear dispersion during interaction of solitons are studied.
