Claim Text:
1. A method for operating an optical modulator of the kind that has a bias voltage and a bias phase as operational parameters, comprising: selecting an operating point that consists of a bias voltage paired with a bias phase, wherein the selection is made from a parameter space of paired bias voltages and bias phases, and wherein the selection is more particularly made from a region of the parameter space that is designated a low-distortion region; configuring the modulator to operate at the selected operating point by setting a base value of the bias voltage and setting at least one other parameter independent of the bias voltage; and operating the optical modulator according to the selected operating point by transmitting at least part of an optical beam on a waveguiding path and applying the bias voltage across one or more p-n junctions that traverse the waveguiding path.
