Abstract

This paper obtains optical soliton solutions in magneto-optic waveguides with several perturbation terms. In addition to group-velocity dispersion, spatio-temporal dispersion term is taken into consideration. There are three types of nonlinear media studied in this paper. They are Kerr law, power law and log-law nonlinearities. Bright, dark and singular soliton solutions are obtained. Numerous constraint conditions naturally emerge for solitons to exist..
