  • Process for preparing silica or silica-based thick vitreous films according to the sol-gel technique and thick films thereby obtained
    Patent number: 6852300
    Abstract: A sol-gel process allowing preparation, on a substrate, of glassy films of silicon oxide or mixed oxides based on silicon oxide, of thickness above 1 micrometer, generally between 2 and 20 micrometers and characterized by absence of defects, that turn out to be particularly suitable as waveguides in flat optical devices.
