Abstract
An optical waveguide is disclosed which comprises a substrate of A12O3 and a silica glass film of SiO2 applied thereon. The glass film has between 35-90 mol % SiO2. The device may be used in conjunction with electronics on the same substrate to form opto-electronic interconnections. The invention may also be used to apply a thin film glass glaze to a ceramic substrate.
