- Abstract
In the present investigation, we employed the Jacobi elliptic function (JEF) method to invoke the perturbed nonlinear Schrodinger equation with self-steepening (SS), self-phase modulation (SPM), and group velocity dispersion (GVD), which govern ¨ the propagation of solitonic pulses in optical fibres. The proposed algorithm proves the existence of the family of solitons in optical fibers. Consequently, chirped and chirp free W-shaped bright, dark soliton solutions are obtained from dn(ξ ), cn(ξ ) and sn(ξ ) functions. The final results are displayed in three-dimensional plots with specific physical values of GVD, SPM and SS for an optical fiber.
