Abstract

An electronic compensation circuit in which a simulation of a laser's thermal droop characteristics is used to adjust input to the laser and thereby compensate for the laser's thermal droop effects The simulation circuit is connected to the laser either as an open loop circuit to provide a once only correction or as a closed loop feedback circuit to provide a continuous correction of the laser droop effects. The simulation circuit is designed using either analog or digital circuitry and is adjustable to provide compensation for lasers having different time constants of droop or different values of droop.
