New combo and dipole solitons in multiple-core couplers with dual dispersion

This paper is concerned with combo and dipole solitons in nonlinear directional optical couplers using Kerr law media. The governing model is multiple-core couplers with group velocity dispersion (GVD) and spatio-temporal dispersion (STD) described by a nonlinear Schrödinger's equation (NLSE). The Ansatz method is used to construct these combo and dipole solitons. The necessary conditions for the existence of these solitons is also given.
