Abstract
In an asynchronous optical modulation system, a drive circuit may generate a plurality of dither tones in accordance with a predetermined dither frequency ratio. Based on the components of the dither frequency ratio, the optical modulation system may be configured to determine a feedback signal magnitude component that is independent of the delay τ and a feedback signal sign component that is also independent of the delay τ. A feedback signal that is independent of the delay τ can then be reconstructed based on the feedback signal magnitude component and the feedback signal sign component.
