Abstract

Because sol-gel is a convenient technique for the fabrication of oxide coatings, many researchers have investigated its application in the fabrication of optical waveguides. Optical fibers can also be manufactured using sol-gel preforms [1, 2], but we will concern ourselves here with planar geometries. Light will be guided in any transparent dielectric material surrounded by a dielectric of lower refractive index. Thus the simplest thin film waveguide geometry, and hence the most studied, is obtained by depositing a coating on a transparent substrate of lower index than the coating.
