Silica-Based Photonic Materials for Integrated Optics

The quality of the controllable optical index films based on silica photonic materials for integrated optics depends mainly on the thermal treatment. The microstructural properties of TiO₂ in (1-X) SiO₂ XTiO₂ system during the curing process were elucidated by using of the thermo-, X-ray analysis, and MicroRaman. In regard to active materials, the fluorescence spectra and it's lifetime of Eu ³⁺ doped SiO₂ /TiO₂ films were measured to investigate the influence of treatment temperature, activators concentration and fabrication conditions of the doped film systems.
