  • Fabrication of long range periodic nanostructures in transparent or semitransparent dielectrics
    Patent number: 7438824
    Abstract: To make high quality long-range periodic nanostructures in a transparent or semi-transparent substrate, the transparent or semi-transparent substrate is scanned with a linearly polarized laser beam generated by a femtosecond laser and exceeding a predetermined energy/pulse threshold along a scanning path. Sub-diffraction limit structures are formed as periodic planes of modified material in the transparent or semi-transparent substrate extending along the scanning path. The modified material can then be chemically etched to form cavities.
    Type: Grant
    Filed: March 24, 2006
    Date of Patent: October 21, 2008
    Assignee: National Research Council of Canada
    Inventors: Rod Taylor, Paul Corkum, Ravi Bhardwaj Vedula, Eli Simova, David Rayner, Cyril Hnatovsky
