This paper obtains the exact 1-soliton solution of the perturbed Korteweg-de Vries equation with power law nonlinearity. The topological soliton solutions are obtained. The solitary wave ansatz is used to carry out this integration. The domain restrictions are identified in the process and the parameter constraints are also obtained. It has been proved that… (More)
—The transmission speed of optical networks strongly depends on the impact of higher order dispersion. In the presence of coherent interference which can't be kept under control by optical filtering, the impact of higher order dispersion becomes more serious. In this paper we give general expressions that describe pulse deformation due to even higher order… (More)
This letter studies optical solitons that is governed by the nonlinear Schrödinger's equation with dual-power law nonlinearity and including the fourth order dispersion term. The solitary wave hypothesis is used to obtain the closed form 1-soliton solution. The restriction on the parameters are also obtained, during the course of derivation of the solution,… (More)
In this paper, a closed form optical soliton solution is obtained for the nonlinear Schrödinger's equation with fourth order dispersion in a Kerr law media. The solitary wave ansatze is used to carry out the integration of this equation. Finally, a numerical simulation is given for the closed form soliton solution.
