Multisoliton Solutions and Breathers for the Coupled Nonlinear Schrodinger Equations via the Hirota Method

摘要

Under investigation in this paper are the coupled nonlinear Schrodinger (CNLS) equations with dissipation terms by the Hirota method, which are better than the formal Schrodinger equation in eliciting optical solitons. The bilinear formhas been constructed, via which multisolitons and breathers are derived. In particular, the three-bright soliton solution and breathers are derived and simulated via some pictures. The propagation characters are analysed with the change of the parameters.
