  • Abstract
    WO3 coatings on Ti:LiNbO3 optical waveguides have been prepared from tungsten ethoxide by a sol-gel method. The annealed coatings display a triclinic perovskite crystalline structure determined by X-ray diffraction. Optical tests show that output power of the straight line waveguide decreases after deposition of the coatings (from 62 μW to 25 μW in the presence of saturated ethanol vapour)
