Sol-gel techniques were used to prepare SiO 2{single bond}TiO 2 planar and strip optical waveguides. Thermal densification for planar waveguides and laser densification for strip waveguides were performed on films prepared from two different solutions on silica and soda-lime substrates. The resulting waveguides were optically characterized and the optical differences between furnace- and laser-densified films were shown. A better insight of the effect of the densification method, solution and substrate on the resulting film was gained by the study of their chemical composition by nuclear analyses.

Abstract
Sol-gel techniques were used to prepare SiO 2{single bond}TiO 2 planar and strip optical waveguides. Thermal densification for planar waveguides and laser densification for strip waveguides were performed on films prepared from two different solutions on silica and soda-lime substrates. The resulting waveguides were optically characterized and the optical differences between furnace- and laser-densified films were shown. A better insight of the effect of the densification method, solution and substrate on the resulting film was gained by the study of their chemical composition by nuclear analyses.File in questo prodotto:
