Abstract
An apparatus of automatic power control for burst mode laser transmitter and method are provided. In one implementation a method includes: generating an output current with a modulation pattern determined by a transmit data and a transmit enable signal, and a modulation level determined by a first control code and a second control code, wherein a light signal is generated in response to the output current; generating a first decision based on a comparison between a photodiode current and the first reference current, a second decision based on a comparison between the photodiode current and the second reference current, wherein the photodiode current is generated in accordance to the light signal; and generating the first control code and the second control code in response to the first decision and the second decision.
