To describe the propagation of this kind of electromagnetic modes, the nonlinear Schrodinger equation (NSE) has been used. a phase- plane method has been used for a quality description and mechanical interpretation for this model of propagation. TE modes can propagate along the interface of two self-focusing nonlinear media (with Kerr-type nonlinear). And the complex form of the electric field amplitude in NSE leads to a certain kind of modes which are called special solitons.
