Photovoltaic spatial solitons and periodic waves in a photovoltaic crystal

A coupled nonlinear Schro center dot dinger equation describes the propagation of a spatial-phase-modulated photovoltaic soliton and a non-phase-modulated beam in a photovoltaic crystal. With the help of the Jacobian elliptic function method and the leading term analysis, three kinds of Jacobian elliptic function solutions including coupled sn-cn type solution, coupled sn-dn type solution and solution constructed by products of elliptic functions are reported. In the long wave limit, these solutions become dark-bright soliton pair solution and coupled twin-peaked type solution. From these solutions, the amplitude, width and frequencies of solitons are determined by the Glass constants of the spatial-phase-modulated, non-phase-modulated and background beams.

Automated summary

A coupled nonlinear Schrodinger equation is used to describe the propagation of spatial-phase-modulated photovoltaic solitons and non-phase-modulated beams in a photovoltaic crystal. Through the use of Jacobian elliptic function solutions, the characteristics of these solitons in the long wave limit are determined by the Glass constants of the beams.
