ABSTRACT
The paper presents the results of investigation which demonstrate the possibilities to shape refractive index profiles of planar waveguides produced in glass using the ion exchange technique with the application of electrodiffusion processes with the change of direction of electric field polarization. We also attempted to determine equilibrium concentration of mobile glass ions based on the value of electric charge passing through glass in the electrodiffusion process.
