Peculiarities of Light Scattering on the Rough Surface of a Gradient Waveguide

Resumo

Some peculiarities of light scattering in thin-film and gradient waveguides are found. For ion-exchange fabricated waveguides a developed model of refractive index function is proposed. The maximum sensibility of the roughness spectrum waveguide measurement method is derived for waveguides with different index functions in near-surface region.
