ABSTRACT:
The present invention relates to an actuator and optical attenuator using the actuator. The rotary-type comb-drive actuator includes a substrate, a movable electrode, a drive electrode, one or more vertical springs, one or more vertical spring anchors, a horizontal spring and a horizontal spring anchor. The movable electrode is arranged on a plane of the substrate to be movable in parallel to the substrate plane, and formed to have a predetermined length so as to have a comb-shaped electrode comprised of a plurality of fingers. The drive electrode is formed to have a length corresponding to that of the movable electrode, and formed to have a comb-shaped electrode that is comprised of a plurality of fingers and arranged to be interdigitated with the comb-shaped electrode of the movable electrode. The vertical springs are arranged in parallel to the substrate, and connected to be perpendicular to the movable electrode on both sides of a first end of the movable electrode. The vertical spring anchors are connected to the vertical springs to support the vertical springs. The horizontal spring has a main part connected in parallel to a longitudinal direction of the movable electrode. The horizontal spring anchor is connected to the horizontal spring to support the horizontal spring, and fixed on the substrate.
