Abstract
Planar step-index waveguides of SiO2:TiO2 and ZrO2:CeO2 in multilayer structures were prepared onto commercial glass substrates using a sol-gel technique combined with dip-coating. These coatings were previously optically characterized by Ellipsometry. These glassy coatings were structural characterized by Transmission Electron Microscopy (TEM), Energy Dispersive X-ray analysis and Confocal Microscopy. Thicknesses of 1050 nm and 500 nm and refractive indices of 1.64 and 2.07 for SiO2:TiO2 (70:30) and ZrO2:CeO2 (70:30) waveguides were obtained, respectively, by the analysis of the guided TE and TM modes observed by Dark m-line Spectroscopy. Losses of 1.32 dB/cm and 0.86 dB/cm were respectively measured by a method based on scattered light.
