Breather-to-soliton and rogue wave-to-soliton transitions in a resonant erbium-doped fiber system with higher-order effects

摘要

Under investigation in this paper is the higherorder nonlinear Schrodingerand Maxwell-Bloch (HNLSMB) system which describes the wave propagation in anerbium-doped nonlinear fiber with higher-order effects including thefourth-order dispersion and quintic nonKerr nonlinearity. The breather androgue wave (RW) solutions are shown that they can be converted into varioussoliton solutions including the multipeak soliton, periodic wave, antidarksoliton, M-shaped soliton, and W-shaped soliton. In addition, under differentvalues of higher-order effect, the locus of the eigenvalues on the complexplane which converts breathers or RWs into solitons is calculated.
