The rogue waves with quintic nonlinearity and nonlinear dispersion effects in nonlinear optical fibers

We study on rogue waves in a nonlinear fiber with cubic and quintic nonlinearities, linear and nonlinear dispersion effects. We find the rogue wave with these higher order effects has identical shape with the well-known one in nonlinear Schrodinger equation. However, the quintic nonlinear term and nonlinear dispersion effect affect the velocity of rogue wave, and the evolution of its phase. (C) 2014 Elsevier B.V. All rights reserved.
