  • Patent number: 7864409
    Abstract: The present invention relates to a fabrication method for a quasi-phase-matched waveguide. The method includes the steps of forming a metal etch mask on a ferroelectric single crystal substrate, etching the substrate by using the etch mask, removing the etch mask, forming conductive layers on the etched substrate, forming polarization regions by applying an electric field to the conductive layers, and flattening the substrate after removing the conductive layers. Accordingly, the present invention is advantageous in that it can be applied to various fields employing a ferroelectric substrate, such as LiNbO3, LiTaO3, Mg:LiNbO3 or Zn:LiNbO3, it can obtain more accurate and uniform periodic domain inversion devices with a high quality and can fabricate devices that are cheaper and have a better performance.

  • Patent number: 6558878
    Abstract: Disclosed is a microlens manufacturing method which comprises the step of: positioning a X-ray mask for manufacturing the microlens on an substrate on which a sensitive film is formed, and arranging a rotation axis of the substrate and a central axis of the X-ray mask; applying X-rays to the X-ray mask to expose the sensitive film while fixing the X-ray mask and rotating the substrate; developing the sensitive film to form the microlens; performing an electroplating process on the plating base to form a metal layer; and separating the metal layer from the sensitive film structure and combining the metal layer with a mold frame for injection molding the microlens and manufacturing an injection mold.
