We experimentally demonstrated the ditherless auto bias control operation for a dual-polarization IQ modulator using genetic algorithm-based control for initialization process and greedy method of fine control for tracking process. In the actual modulator measurement, the best value of the average error vector magnitude is 10.3% after tracking process.
