This paper uses the transversal equivalent network method for calculating the dispersion relations and field distributions of stationary nonlinear TM waves guided,by optical planar waveguides with intensity dependent permittivities.In this method,the electromagnetic field problem of nonlinear dielectric waveguide is equivalent to network problem by using the transmission line theory,the governing Eigen equation is then obtained by the transversal resonance technique.The numerical results for TM waves guided by a three layer nonlinear waveguide have been presented for different mechanisms of the nonlinearity.
