Gilles L. Tourte has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method and apparatus for inducing an index of refraction change on a substrate sensitive to electromagnetic radiation
    Patent number: 7418162
    Abstract: An apparatus for inducing of the index of refraction of a substrate sensitive to electromagnetic radiation. The apparatus is capable of generating a first beam of electromagnetic radiation and a second beam of electromagnetic radiation that is different from the first beam. The first and the second beams converge toward a treatment area on the substrate, which is illuminated with electromagnetic radiation. The first beam and the second beam interact to create an interference pattern over a limited portion of the treatment area.
    Type: Grant
    Filed: March 1, 2007
    Date of Patent: August 26, 2008
    Assignee: Lxsix Photonics Inc.
    Inventors: Claude Beaulieu, Paul Lefebvre, Gilles L. Tourte, André R. Vincelette
  • Method and apparatus for inducing an index of refraction change on a substrate sensitive to electromagnetic radiation
    Patent number: 7277604
    Abstract: An apparatus for inducing a modification of the index of refraction of a substrate sensitive to electromagnetic radiation. The apparatus is capable of generating a first beam of electromagnetic radiation and a second beam of electromagnetic radiation that is different from the first beam. The first and the second beams converge toward a treatment area on the substrate, which is illuminated with electromagnetic radiation. The first beam and the second beam interact to create an interference pattern over a limited portion of the treatment area.
