Generalized coupled nonlinear equations for the analysis of asymmetric two-core fiber coupler.
Studies have shown that 1st order coupling coefficient dispersion can cause significant effects on the propagation of short pulses in a twincore coupler. In this paper, we have extended the study to the case of nonidentical cores and investigated the effect of 2nd order dispersive coupling coefficient on switching dynamics. A pair of new coupled nonlinear equations have been presented and analyzed.
