Experimental analysis of Ag+‐Na+ exchange in glass with Ag film ion sources for planar optical waveguide fabrication

A detailed experimental analysis of Ag+‐Na+ ion exchange in glass using Ag films as ion sources for the fabrication of planar optical waveguides has been performed. The refractive index profiles of the waveguides have been measured and compared to the theoretical Ag+ concentration profiles. The theoretically predicted special characteristics of the process are verified and the material parameters of the used substrate glass (Corning 0211) are evaluated.
