Exact optical solitons of Radhakrishnan-Kundu-Lakshmanan equation with Kerr law nonlinearity

摘要

A new generalized exponential rational function method (GERFM) is used to acquire some new optical solitons of Radhakrishnan-Kundu-Lakshmanan (RKL) equation with Kerr nonlinearity. This equation is used to model propagation of solitons through an optical fiber. The well-known exponential rational function method is also a special case of the GERFM. The results reveal that the mentioned method is efficient and simple for solving different nonlinear partial differential equations.
