Patents by Inventor Sanjeev Murthy

Sanjeev Murthy 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).

  • Photonic integrated circuits having chirped elements
    Patent number: 8705904
    Abstract: Consistent with the present disclosure, optical devices are provided along different optical paths in a photonic integrated circuit (PIC). The optical components have different optical losses associated therewith so that optical signals propagating in the optical paths have desired power levels, which may be uniform, for example.
    Type: Grant
    Filed: November 1, 2008
    Date of Patent: April 22, 2014
    Assignee: Infinera Corporation
    Inventors: Fred A. Kish, Jr., Mehrdad Ziari, Radhakrishnan L. Nagarajan, Masaki Kato, Vincent G. Dominic, Sanjeev Murthy, Alan Nilsson
  • Tunable photonic integrated circuits
    Patent number: 8155531
    Abstract: Photonic integrated circuits (PICs) may include transmit and receive PICs that include individually tunable optical elements. In one implementation, a device may include a number of optical elements that form a number of optical channels. Tuners may be used to modify a property associated with the at least one of the optical elements where the modified properties of the optical elements adjust a frequency grid of the optical channels.
