摘要
The present disclosure provides Radio Frequency (RF) drive level control systems and methods for an Electro-Optic (EO) M-ary Phase-Shift Keying (M-PSK) phase modulator. Specifically, an M-PSK drive waveform is tightly controlled for maximum symmetry in the associated constellation. In an exemplary embodiment, the present disclosure includes an M-PSK transmitter, an M-PSK electro-optic phase modulator, and phase modulation method that each control RF drive level based upon a carrier suppression ratio defined as a measure of ratio of a modulated time-averaged E-field to the magnitude of the E-field. In an exemplary embodiment, the carrier suppression ratio is measured based on a modulation depth measurement.
