A planar optical waveguide fabrication is reported using a silver-sodium, electric field enhanced, Al thin film masked, ion exchange process. In this study, silver atoms from the thin film replace the sodium ions in soda-lime glass, resulting in a higher index of refraction. It should be noted that soda lime glass was used as a substrate even though it varies in composition, contains metallic impurities and is generally not of optical quality. Problems related with sterling silver and design width are discussed. A better understanding of requirements for coupling light into the waveguide, edge polishing, index profiling, focusing of the source etc, is needed to further analyze this wave guide.
