Abstract
Tunable laser systems use servo control loops to control and monitor laser parameters such as channel, temperature, and power. The many control loops operate asynchronously, which means that noise generated by input sampling and/or output updating from one or more loops could interfere with the sampled inputs of one or more of the other loops. Embodiments of the present invention synchronize setting and sampling of tunable laser parameters to reduce noise. Noise that is related to synchronized setting and sampling of tunable laser parameters allows the noise to be reduced to constant offsets to be compensated for in the laser parameters of interest.
