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
