  • Laser package
    Patent number: 6611001
    Abstract: A compact laser package having a submount with a plurality of electrical contact pads and a plurality of electrical connection lines formed thereon. The submount may be configured to receive at least one optical component thereon, the at least one optical component being in electrical communication with at least one of the plurality of electrical connection lines. A lid is provided, the lid having a recessed portion and a groove formed therein, the recessed portion being positioned in an interior of the lid and the groove being positioned to intersect the recessed portion and a peripheral edge of the lid. The submount is generally configured to cooperatively engage the lid to form a hermetically sealed laser package.
    Type: Grant
    Filed: February 6, 2001
    Date of Patent: August 26, 2003
    Assignee: Lucent Technologies Inc.
    Inventors: Mark Anthony Cappuzzo, John Van Atta Gates, II, Louis T. Gomez, Gerard Edmond Henein, Isaac Ryazansky, Joseph Shmulovich

  • Multi-stage optical fiber amplifier having high conversion efficiency
    Patent number: 6104733
    Abstract: We have found that the conversion efficiency of a Er/Yb-doped cladding pumped fiber amplifier increases with increasing signal input power. Thus, preamplification of the input signal by means of an Er-doped fiber amplifier can result in increased conversion efficiency of the cladding pumped power amplifier. Such increased efficiency is desirable, lessening heat removal problems and/or facilitating increased reliability.
