Systems and methods are provided for an optical modulation feedback circuit. The feedback circuit includes a low frequency comparison circuit configured to receive a monitoring signal generated by an optical detector, the monitoring signal being proportional to an amount of light generated by an optical transmission device that transmits based on a data signal that is received by an optical driver. The comparison circuit is further configured to generate a modulation control feedback signal that is transmitted to the optical driver based on a comparison of a low frequency component of the monitoring signal and a low frequency component of the data signal.
