Abstract
Various embodiments of the present invention relate to systems and methods for monitoring and tuning detector and modulator resonators during operation. Aspects of the present invention use DC balanced coding of data in optical signals tune and monitor the performance of a resonator. Whether the resonator is being used as a modulator or a detector, the intensity of the light coupled into the resonator is DC balanced and varies as a function of the data being transmitted. Average intensity variations of the light scattered from the resonator are converted into an electronic feedback signal, which is used to determine appropriate levels of thermal and electronic tuning applied to the resonator.
