Abstract

Summary form only given. Pulse propagation in a nonlinear optical medium is described by the nonlinear Schrodinger equation (NLSE). For large wavelength division multiplexing (WDM) systems, the simulation time can run into weeks. We developed a new, flexible, fast and adaptive split-step wavelet collocation method (SSWCM) which provides a substantial speed-up compared to the standard split-step Fourier method (SSFM).
