Abstract : pplications to act as inter connectors, optical switches and routers. In the present study planar waveguides of nonlinear metal oxides MgO, TiO2 and ZnO as core material with a triangular refractive index profile are modeled for various input wavelengths. The variation in refractive index with input wavelength induces nonlinearity in these waveguide structures. A numerical continuation procedure is employed using an initial soliton solution for a triangular refractive index profile. An oscillatory wave path in the waveguide structures is seen to result. By doping an increase in refractive index of the core is achieved whereby oscillatory nature can be eliminated.
