Optical And Microanalytical Characterization Of K+-Na+ Ion Exchanged Optical Waveguides

An optical and microanalytical investigation of optical waveguides prepared by K+-Na+ ion exchange in glass is presented. Refractive index profiles and ion concentration profiles are compared, for waveguides prepared on soda lime glass at different processing times and temperatures; this comparison allows a reliable separation of the composition and the stress optical contributions to the resulting refractive index change.
