Abstract
Operator splitting techniques such as the split-step Fourier method or the split-step wavelet method have been successfully used for numerical simulation of uniformly time-sampled pulses along nonlinear optical fibers. In this letter, we extend the operator splitting technique to derive a novel numerical algorithm based on cubic B-splines for simulating propagation of nonuniformly sampled optical pulses along nonlinear optical fiber. We present numerical simulation results supporting the validity and accuracy of the proposed method.
