Abstract

In dual-core fibers the variation of the coupling coefficient with frequency leads to intermodal dispersion that perturbs the switching of ultrashort pulses. Using a new version of the split-step Fourier method based on a model that includes intermodal dispersion, we show that this effect cannot be neglected when the switching of picosecond solitons at different wavelengths in half-beat twin-core fiber couplers is analyzed, although picosecond solitons at the central wavelength are not significantly affected. We also show that to study the switching of wavelength-division-multiplexed solitons one should always take into account the effect of intermodal dispersion.
