Abstract

We present results from a wavelet based model for pulse propagation in optical fibres and semiconductor optical amplifiers that agree closely with split step Fourier results. The propagation is simulated with O(N) computational complexity compared with the O(NlogN) complexity of fast Fourier transform based methods, yielding a possible speed advantage, especially if N is large. The method could be extended to other optical communications components, e.g. the Ginzberg-Landau equations for propagation in fibre amplifiers
