Patents by Inventor Jesper Arentoft Jayaswal

Jesper Arentoft Jayaswal 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 to generate and monitor optical signals and control power levels thereof in a planar lightwave circuit
    Patent number: 8057108
    Abstract: Embodiments of an optical detection apparatus are disclosed which may include one or more of a waveguide, a trench formed in the waveguide, a reflective surface, and a photodetector. The waveguide may be formed in a semiconductor substrate to propagate an optical signal received at a first end of the waveguide. The trench may also be formed in the waveguide having a first sidewall and a second sidewall, the first and second sidewalls forming first and second angles with the waveguide's propagation direction. The second sidewall may include a reflective surface formed thereon. The photodetector may be configured to receive an optical signal propagated in the waveguide, through the first sidewall and reflected from the reflective surface on the second sidewall.
    Type: Grant
    Filed: July 30, 2010
    Date of Patent: November 15, 2011
    Assignee: Intel Corporation
    Inventors: Achintya K. Bhowmik, Nagesh K. Vodrahalli, Gennady Farber, Hai-Feng Liu, Hamid Eslampour, Ut Tran, William B. Wong, Ruolin Li, Jesper Arentoft Jayaswal
