Abstract
An electro-optical modulator includes a substrate, a first electrode over the substrate, a second electrode over the first electrode, the first electrode and second electrode being capable of providing an electric field between the first electrode and the second electrode, and a modulating structure between the first electrode and the second electrode, the modulating structure containing at least one liquid crystal cell capable of operating in one of a reflective mode and a transmissive mode under the control of the electrical field.
