摘要：

An extensive investigation into the optical properties of K** plus -Na** plus ion-exchanged waveguides in soda-lime glass over a wide range of time and temperature is described. From accurate measurements of effective indices, refractive-index profiles and birefringence are obtained, and by use of microanalytical techniques (RBS, EDX) ion concentration profiles are measured. Comparison of these profiles allows a quantitative separation of the compositional and stress optical contributions to the overall change in refractive index; the time behavior of stress thermal relaxation processes explains the evolution of the profile shape.
