  • Customizing the refractive index of a surface
    Patent number: 10983255
    Abstract: Mechanisms for customizing a refractive index of an optical component are disclosed. In one example, sub-wavelength openings are formed in a top layer of anti-reflective (AR) material of an optical component to tailor transmission characteristics of the AR material over a range of angles of incidence and a range of wavelengths. In another example, sub-wavelength openings are formed at different filling fractions in the surface of the optical component.
    Type: Grant
    Filed: December 8, 2016
    Date of Patent: April 20, 2021
    Assignees: Lockheed Martin Corporation, The Penn State Research Foundation
    Inventors: Clara R. Baleine, Corey L. Bungay, Theresa S. Mayer, Andrew Swisher, Jeffrey L. Ruckman, Stephen R. Tuenge

  • Electroformed buried gratings for high-power shared aperture systems
    Patent number: 5323266
    Abstract: A two-metal grating is produced by vacuum depositing a first dielectric cing upon a separation layer formed upon a mandrel; then depositing a first optically opaque metallic layer, etching the layer to form stripes; then vacuum depositing a second optically opaque film; then electroforming a backing structure and separating the dielectric coating from the separation layer on the mandrel to form a free-standing grating structure having a smooth surface. This structure can then be affixed to a metallic mirror. A buried phase grating can also be fabricated by additionally depositing a second dielectric layer and a third metallic layer.
