Abstract
A phase modulation active device and a method of driving the same are provided. The method may include configuring, for the phase modulation active device including a plurality of channels that modulate a phase of incident light, a phase profile indicating a phase modulation target value to be implemented by the phase modulation active device; setting a phase limit value of the phase modulation active device; generating a modified phase profile based on the phase profile by modifying the phase modulation target value, for at least one channel from the plurality of channels that meets or exceeds the phase limit value, to a modified phase modulation target value that is less than the phase limit value in the phase profile; and operating the phase modulation active device based on the modified phase profile. Thus, improved optical modulation performance may be achieved.
