Sarah L. Fogal 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 system for the controlled production of polarization mode dispersion
    Patent number: 7289708
    Abstract: A method and a system to produce, either in numerical simulations or in experiments, specified amounts of first, second and higher order PMD in a controlled manner, in particular large amounts. Parameters can be adjusted to obtain specific ranges of first, second and higher order PMD, and importance sampling can be used to determine the probability that the resulting PMD events can be obtained in realistic situations. Individual results obtained using specific parameter values can be combined to produce even larger ranges of PMD.
    Type: Grant
    Filed: June 26, 2006
    Date of Patent: October 30, 2007
    Assignee: Northwestern University
    Inventors: William L. Kath, Gino Biondini, Sarah L. Fogal
