ABSTRACT:
An optically controlled device includes a transparent electrode, a conductivity variable portion, a driving electrode, a movable unit, and a support portion. A method of controlling the optically controlled device includes inputting a control light into the transparent electrode, applying a voltage modulated according to an input signal between the transparent electrode and the movable unit, and moving the movable unit to a predetermined position by generating a force corresponding to the voltage between the driving electrode and the movable unit base on a charge of electrical conductivity of the conductivity variable portion.
