ABSTRACT:
A control circuit for an injection laser includes a driver circuit which applies a driving current to the laser in response to an electrical modulating signal. A prebias circuit applies a prebias current to the laser in response to the difference between a signal derived from the electrical modulating signal and a signal derived from the laser light output.
