Optical soliton perturbation with full nonlinearity for Kundu-Eckhaus equation by extended trial function scheme

The dynamics of soliton propagation through optical fibers, modeled by perturbed Kundu-Eckhaus equation, is studied in this paper by the aid of extended trial function scheme. The perturbation terms are all of Hamiltonian type that appears with full nonlinearity. Bright and singular soliton solutions are secured with this integration scheme.
