Abstract

TM modes in a nonlinear isotropic Kerr film embedded between two linear media are analyzed. It has been proved that an exact analytical solution that corresponds to a certain class of modes does exist in such a structure. This solution describes balanced modes: the guided electromagnetic fields have two electric components of equal amplitude. An analogous analytical but approximate solution has been derived for the fields close to the balanced modes. The closed-form mode equation and the power flow relation that correspond to such quasi-balanced modes have been obtained. The results are compared with the exact numerical solution and the transverse uniaxial approximation.
