Numerical calculation methods are usually more widely applied in NLSE because of its complexity. The most commonly used algorithm is the split-stepFouriermethod (SSFM).
The fiber propagation model can be described by the nonlinear Schrodinger equation, and the split-stepFouriermethod is used extensively to solve the pulse-propagation problem.
