Abstract
A method and apparatus for controlling the power of laser diodes are provided. The apparatus includes an output voltage sensor, which senses output voltages of at least two laser diodes and outputs the output voltages to an optical power controller. The optical power controller generates control voltages for controlling the at least two laser diodes by performing proportional-integral (PI) control on error voltages between reference voltages and the output voltages received from the output voltage sensor.
