摘要：A method for determining, by a modulator assembly, an optimal drive point for a Mach-Zehnder modulator (MZM). The modulator assembly applies an electrical modulation signal to the MZM to modulate an optical input signal and create a modulated optical output signal, the modulated optical output having a spectrum that includes a first and third harmonic. The modulator assembly measures the difference in magnitude between the first harmonic and the third harmonic as the amplitude of the electrical modulation signal is varied, and determines a value for the amplitude of the electrical modulation signal that corresponds to a maximum difference between the first harmonic and the third harmonic.
