Abstract :
Optical waveguides were formed by increasing the index of refraction of a glass substrate by exchanging constituent glass ions in a small region near the surface. The glass refractive index is related to the density of the ions and to their polarizabilities. Tl+, K+, and Ag+ions were thermally diffused into the glass and resulted in a region of higher index. Index changes as high as .15 and waveguide thickness up to several microns were measured.
