A novel technique for multi-channel digital backpropagation (DBP) in wavelength-division multiplexing systems is proposed. The nonlinear step of the conventional split step Fourier method (SSFM) is extended to account for the interplay of dispersion and inter- and intra- channel nonlinearities. The technique is referred to as coupled-channel enhanced SSFM and, by simulation, it is shown to provide better performance than existing equivalent complexity single-channel DBP techniques.

Abstract

A novel technique for multi-channel digital backpropagation (DBP) in wavelength-division multiplexing systems is proposed. The nonlinear step of the conventional split step Fourier method (SSFM) is extended to account for the interplay of dispersion and inter- and intra- channel nonlinearities. The technique is referred to as coupled-channel enhanced SSFM and, by simulation, it is shown to provide better performance than existing equivalent complexity single-channel DBP techniques.
