ABSTRACT:
A laser biasing stabilization circuit and method uses the second derivative of the optical light output of a laser with respect to the current through the laser, d.sup.2 L/dI.sup.2, in a feedback loop to control the laser bias current through the laser. The modulation current in the laser is controlled using a second, average power feedback loop.
