The (n+1)/2 rule for dealiasing in the split-step Fourier methods for n-wave interactions

Derevyanko, Stanislav (2008). The (n+1)/2 rule for dealiasing in the split-step Fourier methods for n-wave interactions. IEEE Photonics Technology Letters, 20 (23), pp. 1929-1931.


The aim of this letter is to demonstrate that complete removal of spectral aliasing occurring due to finite numerical bandwidth used in the split-step Fourier simulations of nonlinear interactions of optical waves can be achieved by enlarging each dimension of the spectral domain by a factor (n+1)/2, where n is the number of interacting waves. Alternatively, when using low-pass filtering for dealiasing this amounts to the need for filtering a 2/(n+1) fraction of each spectral dimension.
