Document Type and Number:
Japanese Patent JP2949807
Kind Code:
B2
Abstract:
An optical waveguide, a dielectric device and method for fabricating such devices in which a substrate (1) polarized in a first direction and a dielectric thin film (2) formed on the surface of the substrate and polarized in the opposite direction to the substrate. Parallel grooves (1a) may be formed in the substrate (1). In one embodiment, a first dielectric thin film (2) is formed on the substrate (1) and is formed with grooves (2a) and is polarized in the same direction as the substrate (1). Then, a second dielectric thin film (3) is formed over the first dielectric thin film (2) and it is polarized in a direction which is opposite to the substrate (1) and the first thin film (2).
