Based on the transmission line theory, this method is based on the theory of the transmission line, which is equivalent to the problem of the circuit network in the nonlinear medium waveguides. The problem of the circuit network is solved by using the transverse resonance technique to obtain the dispersion and the field distribution of TM in the nonlinear slab waveguide. EQUATION The TM wave propagation characteristics in three-layer slab nonlinear waveguide under different nonlinear mechanisms are numerically calculated
