Abstract
A compensated laser diode transmitter for high speed data transmission is provided with a pair of current switches, a novel current summing circuit and a novel current sink. The power output of the laser is sensed in real data time and employed to generate instantaneous feedback signals capable of instantaneously rebalancing and maintaining the power output of the laser diode.
