In the fabrication of silica films by sol-gel synthesis, the role of various catalysts is systematically examined. The precursor solutions were made by mixing tetraethylorthosilicate (TEOS), ethanol and water in the molar ratio of 1 : 2 : 2. The spin

A planar silica-titania waveguide doped with CdS nanocrystallites has been fabricated on a silicon substrate. A passive nanoporous host layer and a pure silica buffer layer, of thickness 2.2 and 7.5 µm, respectively, were deposited by the sol-gel te

A vectorial coupled mode theory is used to analyze sol-gel ridge waveguides with UV-light imprinted Bragg grating. The effect of device parameters on grating reflectivity is investigated. It is shown that 100% reflectivity for both TE and TM modes ca
