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.
