  • Method for the fabrication of patterned poled dielectric structures and devices
    Patent number: 6631024
    Abstract: The present invention concerns a method for fabricating a patterned, poled dielectric structure, comprising the steps of providing a material, patterning a periodic pattern into a first surface, applying an electrode to the first surface, and applying a voltage to the electrode to create a domain inversion in the material. Preferably, the material is a ferroelectric material, and the electrode is a single, planar, solid electrode. The method proposed herein is simple, reproducible and economical, as compared to prior methods. Patterned, poled dielectric structures are used to generate optical frequency conversion, by creating quasi-phase matching between two optical signals.
