摘要

We present a rational solution for a mixed nonlinear Schr(o)dinger (MNLS) equation.This solution has two free parameters,a and b,representing the contributions of self-steepening and self phase-modulation (SPM) of an associated physical system,respectively.It describes five soliton states:a paired bright-bright soliton,a single soliton,a paired bright-grey soliton,a paired bright-black soliton,and a rogue wave state.We show that the transition among these five states is induced by self-steepening and SPM through tuning the values of a and b.This is a unique and potentially fundamentally important phenomenon in a physical system described by the MNLS equation.
