  • Semiconductor optical amplifier having a non-uniform injection current density
    Patent number: 7929202
    Abstract: A semiconductor optical amplifier (SOA) with efficient current injection is described. Injection current density is controlled to be higher in some areas and lower in others to provide, e.g., improved saturation power and/or noise figure. Controlled injection current can be accomplished by varying the resistivity of the current injection electrode. This, in turn, can be accomplished by patterning openings in the dielectric layer above the current injection metallization in a manner which varies the series resistance along the length of the device.
    Type: Grant

    Date of Patent: April 19, 2011
    Assignee: Thorlabs Quantum Electronics, Inc.
