Sol-gel derived PbO-TiO2waveguides were prepared on pyrex substrates using the dip coating technique. Heat treatments conducted at 200[ddot]C, 300[ddot]C and 400[ddot]C for one hour led to the densification of the layers and the increase of the refractive index values. The effect of water concentration in the precursor sol on the optical qualities of the waveguides is reported. Monolayer waveguides prepared with high water concentration provided the best coefficients of attenuation values (< 1 dB/cm). Preliminary study of Waveguide Raman Spectroscopy is presented.
