摘要： The method of manufacturing an optical diffraction grating element of the present invention is characterized in adopting an ion beam made from a gas chemically reacting with a glass substrate when forming a diffraction grating having a serrated profile upon the glass substrate through an ion beam etching method. Also, when manufacturing an optical diffraction grating element that is divided into a plurality of regions whereon diffraction gratings having different diffraction angles with respect to an incident light are provided, the method of the present invention is characterized in forming slits into a resist film disposed upon a transparent substrate such as a glass substrate, in accordance with the patterns of the diffraction gratings, such that the width of the slits is constant irrespectively of the regions. Accordingly, the method of manufacturing an optical diffraction grating element of the present invention enables to improve the diffraction efficiency of the optical diffraction grating element, and to enhance the optical efficiency of an optical head device. The SN ratio of the output signals released by the optical head device may be thus improved and the servo error control executed accurately.

摘要： A method for producing a tapered waveguide layer is disclosed. The method includes the steps of: forming a resist pattern on a substrate; setting the substrate in an apparatus for forming a film such that particles constituting the film reach the substrate from a direction which is oblique relative to the substrate; forming the film on a region of a surface of the substrate which is not covered by the resist pattern, the film having a thickness distribution corresponding to a shadow which the resist pattern creates on the substrate in accordance with an angle between the substrate and the direction; and removing the resist pattern, thereby forming the tapered waveguide layer consisting of the film on the substrate.
