Sunit D. Tyagi 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 for producing fibers having optical effect-producing nanostructures
    Patent number: 9739934
    Abstract: The present technology provides an illustrative method for preparing fibers with desirable optical characteristics. The method includes providing a fiber that comprises a core layer and a cladding layer located around the core layer. The method further includes applying a nanostructure template to the cladding layer to form one or more photonic nanostructures having nanostructure scales and compressing the core layer to cause the core layer to bulge and form air gaps between the core layer and the one or more photonic nanostructures.
    Type: Grant
    Filed: January 6, 2015
    Date of Patent: August 22, 2017
    Assignee: EMPIRE TECHNOLOGY DEVELOPMENT LLC
    Inventors: Hemanshu D. Bhatt, Sunit D. Tyagi
