Based on some experimental results we report in this paper the modeling of the maximum refractive index difference profile of the optical waveguides obtained in glass by double ion exchange (Ag⁺) using Gaussian and erfc functions. The dependences of the maximum refractive index difference, the center of the Gaussian and erfc functions in depth and width, respectively and the corresponding variances on the technological parameters: the width of the mask (window), the first and the second in-diffusion time of the ions were evaluated. The simulation results can be used for the analysis and the design of the optical integrated devices.
