A comparative study of soliton switching in a two- and three-core coupler with TOD and IMD

A numerical study of soliton switching in a two- and three-core coupler is carried out taking into account the effect of intermodal dispersion and third-order dispersion. A two and three-core coupler with linear and triangular configuration is considered. It is found that the three-core coupler with linear configuration shows the best switching characteristics.
