  • Laser driver circuit
    Publication number: 20030035451
    Abstract: A laser driver circuit includes a biasing current source, a threshold current source, and a modulation current source, wherein the threshold current source produces a threshold current in response to an input signal with an interval exceeding an interval of a modulation current such that said interval of the threshold current includes the interval of said modulation current. The laser driver circuit drives the laser diode by a sum of a continuous bias current, the threshold current and the modulation current.
