The NLS equation is a nonlinear partial differential equation that does not generally lend itself to analytic solutions. A numerical approach is often necessary for an understanding of the nonlinear effects in optical fibers. Several numerical methods were developed during the 1970s for solving the NLS equation. One method that has been used extensively for solving pulse-propagation problems in nonlinear dispersive media is the split-step Fourier method, also known as the beam-propagation method.
