Abstract
Systems and methods for calibrating a ring modulator are described. A system may include a controller configured to provide a first test signal to the ring modulator, determine a first candidate temperature control signal for a heater of the ring modulator when the first test signal is provided to the ring modulator, determine a first optical swing of an optical signal at a drop port of the ring modulator, determine a second candidate temperature control signal for the heater when the first test signal is provided to the ring modulator, determine a second optical swing of an optical signal at the drop port, select an optimal optical swing from the first optical swing and the second optical swing, and select one of the first candidate temperature control signal or the second candidate temperature control signal based on the optimal optical swing selected.
