Exact Solutions to the Nonlinear Schrödinger Equation with Time-Dependent Coefficients

Abstract

In this paper, a trial function method is employed to find exact solutions to the nonlinear Schrodinger equations with high-order time-dependent coefficients. This system might be used to describe the propagation of ultrashort optical pulses in nonlinear optical fibers, with self-steepening and self-frequency shift effects. The new general solutions are found for the general case including the Jacobi elliptic function solutions, solitary wave solutions, and rational function solutions which are presented in comparison with the previous ones obtained by Triki and Wazwaz, who only studied the special case .
