Norman Sze-keung KWONG 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).

  • Lasers with beam-shape modification
    Patent number: 9865993
    Abstract: A beam control structure for semiconductor lasers that allows modification of the shape of a beam allowing, for example, higher coupling into an optical fiber. The structure may comprise one or more of a tilted patio, a staircase, a reflective roof, and a reflective sidewall.
    Type: Grant
    Filed: May 20, 2016
    Date of Patent: January 9, 2018
    Assignee: MACOM TECHNOLOGY SOLUTIONS HOLDINGS, INC.
    Inventors: Cristian Stagarescu, Alex A. Behfar, Norman Sze-keung Kwong

  • Lasers with beam shape and beam direction modification
    Patent number: 9692202
    Abstract: A reflective surface is disclosed in conjunction with a semiconductor laser to shape a laser beam and modify a direction of the laser beam. The reflective surface may be formed on a structure disposed adjacent to a laser structure to allow high coupling of laser light to, for example, a silicon photonics chip or an optical fiber.
