ABSTRACT:
A correlation feedback method and apparatus for multi-channel stabilization of a multi-channel transmitter in which a single external receiver is used to detect the total power output from the multi-channel transmitter and to control each channel by correlating the total power output signal with channel data to measure the channels' signal power and control the output power via a feedback loop. The inventive system is suitable for use with and able to accommodate both integrated lasers and an array of discrete independent lasers; the system is also equally applicable for use with channels comprising random independent data or broadcast data.
