ABSTRACT:
A binary modulation laser driver in which a feedback loop employed in regulating the laser output power during the lower power output bits passes the output of a monitor photodiode through a limiting amplifier set to limit at a value just above lasing threshold, and stabilises the mean value of the limiting value output at a value intermediate its limiting output and half that value.
