Abstract

The light propagation in channel waveguides, formed by silver ion-exchange in glass using dielectric and metallic masks, has been studied. It is shown that the variation of the mode interference pattern with formation process parameters can be predicted with good accuracy using a proposed model of diffusion coefficient dependence on diffusate concentration for solving the exchange equation and computing modes of the resulting refractive-index profile. It is found that the quasi-periodic nature of light propagation in the waveguides is determined by the interference of several lowest even waveguide modes and it is very dependent on the diffusion aperture width.
