Superposed Kuznetsov-Ma solitons in a two-dimensional graded-index grating waveguide

Dai, Chao-Qing; Zhu, Hai-Ping


The (2+1)-dimensional coupled nonlinear Schrรถdinger equation with distributed coefficients in a graded-index grating waveguide is investigated, and an exact two-breather solution for certain functional relations is obtained. From this solution, the superposed Kuznetsov-Ma (KM) solitons can be constructed. The explicit functions that describe the evolution of the peak, width, center, and phase are found exactly, from which one knows that diffraction and chirp factors play important roles in the...[Show more]
