  • On-chip built-in test and operational qualification
    Patent number: 9897648
    Abstract: Operational and functional testing of the optical Physical Media Dependent Integrated Circuits (“PMD ICs”) is achieved by constructing a switchable on-chip load with similar or equivalent electrical characteristics of a targeted photonic device.
    Type: Grant
    Filed: July 30, 2015
    Date of Patent: February 20, 2018
    Assignee: Cosemi Technologies, Inc.
    Inventors: Wu-Chun Chou, Michael Eugene Davis, Charles Phillip McClay
  • Pass device with boost voltage regulation and current gain for VCSEL driving applications
    Patent number: 9641170
    Abstract: A power efficient device for driving a load comprising a low current path and a high current path, wherein the high current path is driven by a first voltage source. In order to accommodate larger turn on voltages of possible load devices while maintaining low power operation, an additional voltage source exceeding the voltage source in the high current path is introduced in the low current path.
    Type: Grant

  • Apparatus and method of packaging two dimensional photonic array devices
    Patent number: 6960031
    Abstract: An optical coupler for forming an optical connection between one or more two dimensional photonic array devices and an optical fiber and for forming an electrical connection between the two dimensional photonic array devices and a substrate, a system including the optical coupler and materials, and methods of forming the optical coupler and system are disclosed. The optical coupler includes a light transmission medium and electrical connectors, which are at least partially encapsulated. In addition, the device includes alignment guides configured to receive guide pins from a fiber optic connector, such that when the fiber optic connector is attached to the optical coupler, fibers of the ribbon align with the two dimensional photonic array device(s) via the light transmission medium.
