Perturbation of Gaussian optical solitons in dispersion-managed fibers

The dispersion-managed optical solitons is studied in this paper in presence of various perturbation terms. The Gaussian solitons are considered and the dynamics of such pulses are obtained in presence of such perturbation terms. The integrals of motion are evaluated. The soliton perturbation theory is exploited to formulate the parameter dynamics of the Gaussian solitons.
