Abstract
Due to the dispersion mismatch between the two supermodes of a two-channel coupler, pulse switching cannot be analyzed without taking into account the effect of intermodal dispersion. Using full numerical simulations, we show the influence of intermodal dispersion on all-optical switching with ultra short pulses in twin-core fiber couplers. For the nonlinear regime, however , only subpicosecond and femtosecond pulses are affected in the cross state since the parallel state remains almost unaffected.
