Liquid-crystal (LC) phase modulators are widely used in optical systems because of their advantages of low power consumption, lightweight, flexible bandwidth adjustment, and non-mechanical movements.

Wireless communications often use a format called phase shifting or phase modulation, in which the signals are shifted relative to one another in time. In this example, the communications signal (blue ...
