In this paper, we present exact N-soliton solution by employing simple, straightforward Darboux transformation based on the Lax pair for Hirota equation, a higher-order nonlinear Schrodinger (HNLS) equation. As examples, one- and two-soliton solutions in explicit forms are given and their properties are also analyzed. A bound solution without interaction will be theoretically predicted if one can...
Stable propagation of single ultrashort (subpicosecond or femtosecond) optical pulses and pulse trains is obtained in numerical solutions of a higher-order nonlinear Schroedinger equation with bandwidth limited amplification and nonlinear gain. It is shown that stable single pulse propagation can be achieved for a broad class of pulses with different initial shapes, and that pulse trains can propagate...
