Stimulated fission of high-order optical breather via pairwise interaction of solitons in model of nonlinear Schr?dinger equation with variable coefficients

摘要

Artificial periodic structures offers an additional degree of freedom in manipulation of nonlinear waves and solitons. It is shown that periodical variation of the coefficients of nonlinear Schr?dinger equation allows to change soliton eigenvalues. Pairwise interaction of solitons is demonstrated. The interacting solitons can be selected by appropriate period of the variation of the coefficients of nonlinear Schr?dinger equation. The proposed approach for controlling soliton eigenvalues allows to manipulate soliton fission process.
