This paper studies optical soliton perturbation that appears with Kerr law nonlinearity having spatio-temporal dispersion. The numerical scheme adopted is the variational iteration method. The perturbation terms are of Hamiltonian type and stem from inter-modal dispersion, self-steepening and nonlinear dispersion. Both bright and dark solitons are taken into consideration.

Keywords : Nonlinear Schrödinger equation; Kerr law nonlinearity; variational iteration method; optical solitons solutions; perturbation.
