  • Optical waveguide which is formed by liquid phase epitaxial growth
    Patent number: 5150447
    Abstract: An optical waveguide, a dielectric device and method for fabricating such devices in which a substrate is polarized in a first direction and a dielectric thin film is formed on the surface of the substrate and polarized in the opposite direction to the substrate. Parallel grooves may be formed in the substrate. In one embodiment, a first dielectric thin film is formed on the substrate and is formed with grooves and is polarized in the same direction as the substrate. Then, a second dielectric thin film is formed over the first dielectric thin film and it is polarized in a direction which is opposite to the substrate and the first thin film.
