AbstractThis paper analyses the dynamics of soliton propagation through optical fibres for the perturbed nonlinear Schrödinger equation with Kerr law and non-Kerr law nonlinearity. Several integration schemes are used to construct solitons to the model. The two forms of nonlinearity that are studied in detail are power law and dual power law, while Kerr law and parabolic law emerge as special cases to these two laws.

Kerr Law Nonlinearity

In this paper, using the methods of ansatz, sine-cosine and He’s semi-inverse variation, non-topological 1-soliton solution to Resonant Nonlinear Schrodinger Equation with Kerr law nonlinearity is obtained. The results show that these methods are very effective ones for finding exact solutions to various types of nonlinear evolution equations appearing in the studies of science and engineering.
