Domain wall arrays, fronts, and bright and dark solitons in a generalized derivative nonlinear Schrdinger equation
We obtain some exact solutions of a generalized derivative nonlinear Schrdinger equation, including domain wall arrays (periodic solutions in terms of elliptic functions), fronts, and bright and dark solitons. In certain parameter domains, fundamental bright and dark solitons are chiral, and the propagation direction is determined by the sign of the self-steepening parameter. Moreover, we also find the chirping reversal phenomena of fronts, and bright and dark solitons, and discuss two different ways to produce the chirping reversal.
