  • Laser driver circuit and system
    Patent number: 7519093
    Abstract: A method, system, and electrical circuit for determining a magnitude of a modulation current provided to a laser device based upon an approximated slope efficiency, wherein the approximated slope efficiency is based upon at least one discrete incremental change in a bias current to the laser device and at least one change in output power from the laser device.
    Type: Grant

  • Laser driver circuit and system
    Patent number: 6928094
    Abstract: A laser driver circuit to provide a current signal to power a laser device is described. A bias current provided to the laser device may be changed while changes in the output power of a light signal from the laser device is monitored. A slope efficiency associated with the laser device may be determined based upon the changes in the bias current and changes in the output power.

  • Laser driver circuit and system
    Publication number: 20050135444
    Abstract: Described is a laser driver circuit comprising a bipolar transistor for transmitting a modulated power signal to a laser device. The bipolar transistor may generate the modulated power signal in response to a modulation current and a base current representative of a serial data signal. The laser driver circuit may further comprise a circuit to combine a replica of the base current with a reference modulation current to provide the modulation current.
