  • Method and apparatus for fabrication of controlled chirp gratings
    Patent number: 9431789
    Abstract: In some aspects of the present application, an apparatus for producing an interference pattern on a photosensitive portion formed on a surface of a sample is disclosed. The apparatus can include an optical system for providing interference between two coherent spherical wavefronts impinging on a thin-film photosensitive material formed on a surface of a sample, wherein a plane of the surface normal of the sample is arranged at an angle with respect to a plane defined by center propagation vectors of the two coherent spherical wavefronts; and one or more actuating elements operable to actuate one or more optical elements in the optical system, the sample, or both the one or more optical elements and the sample in one or more degrees of freedom to control a relative magnitude of a longitudinal and a transverse chirp of the interference pattern.
    Type: Grant

    Date of Patent: August 30, 2016
    Assignee: STC.UNM
    Inventors: Steven R. J. Brueck, Xiang He, Steve Benoit
