| Abstract: | For planar waveguide with Kerr type nonlinear film and linear substrate and cladding, the propagation characteristics of TE modes are analysed by KBM method in perturbation theory. The dispersion equation and modal field function are given by second order approximate formulas. The computation is greatly reduced and the results are exact. Typical examples for symmetric and asymmetric nonlinear waveguides are given. |
