Julie Sheridan Eng 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).

  • High speed SFP transceiver
    Patent number: 7970283
    Abstract: This disclosure concerns optoelectronic transceivers. In one example, a transceiver is implemented as an uncompensated architecture that is substantially compliant with the SFP MSA and is capable of effective operation at a data rate of about 8.5 Gb/s. The transceiver includes a TOSA, ROSA, a printed circuit board, an LDPA disposed on the printed circuit board and configured for communication with the TOSA and the ROSA. Finally, the transceiver includes SFP compliant optical and electrical connections.
    Type: Grant

    Inventors: Giorgio Giaretta, Julie Sheridan Eng, Thomas Gordon Beck Mason
  • Analog laser assembly
    Patent number: 6091756
    Abstract: The invention is a laser assembly for reducing distortion ripple. The assembly includes a spherical lens which has a portion of its surface made optically asymmetric to prevent multiple reflections of scattered light within the lens.
    Type: Grant
    Filed: December 23, 1997
    Date of Patent: July 18, 2000
    Assignee: Lucent Technologies Inc.

  • Semiconductor laser assembly with reduced ripple
    Patent number: 6064527
    Abstract: The invention is a laser assembly with reduced distortion ripple. The assembly includes a spherical lens for collimating light emitted from the laser. The lens is made of a material which attenuates scattered light which is the source of ripple without appreciably affecting the main beam.
    Type: Grant

  • Technique for measuring semiconductor laser chirp
    Patent number: 6026105
    Abstract: A technique for characterizing laser chirp utilizes an optical fiber and its inherent interferometric properties. An RF modulating signal is applied to the laser, where the modulated output signal thereafter propagates through a conventional optical fiber. A photoreceiver and spectrum analyzer are coupled to the opposite end of the optical fiber. By adjusting the power of the applied RF signal, the maximum IIN can be determined. The laser chirp can then be calculated by dividing the measurement frequency by the modulation current associated with the maximum IIN value.
