Abstract: An actuator 100 of the type employing a two-degree-of-freedom vibration system includes: a pair of first mass portions 1, 11; a second mass portion 2 provided between the pair of first mass portions 1, 11; a pair of supporting portions 3, 3 for supporting the pair of first mass portions 1, 11 and the second mass portion 2; at least a pair of first elastic connecting portions 4, 4 which respectively connect the first mass portions 1, 11 to the supporting portions 3, 3 so that each of the first mass portions 1, 11 can rotate with respect to the supporting portions 3, 3; and at least a pair of second elastic connecting portions 5, 5 which respectively connect the second mass portion 2 to the first mass portions 1, 11 so that the second mass portion 2 can rotate with respect to the first mass portions 1, 11. Each of the first mass portions 1, 11 is driven by the application of an alternating voltage, causing the second mass portion 2 to rotate.

Abstract: An actuator having a rotation central axis includes: an insulative frame; movable comb electrodes having first electrode teeth; a movable portion between the movable comb electrodes; supporting portions on the frame supporting the movable comb electrodes and the movable portion; fixed comb electrodes on the frame corresponding to the movable comb electrodes and provided with second electrode teeth; first elastic connecting portions connecting the movable comb electrodes to the supporting portions so each movable comb electrode can rotate around the rotation central axis; and second elastic connecting portions connecting the movable portion to the movable comb electrodes so that the movable portion can rotate around the rotation central axis. Each movable comb electrode is driven by an alternating voltage between each fixed comb electrode and movable comb electrode. Part of the first electrode teeth overlaps part of the second electrode teeth when no alternating voltage is applied.

Abstract: A wavelength-tunable optical filter includes a stationary mirror, a movable mirror disposed so as to face the stationary mirror, an actuating plate for actuating the movable mirror, and a peripheral supporting portion holding the actuating plate which are disposed above a base layer. The movable mirror is displaced by applying a voltage between the electrodes provided on the actuating plate and the base layer, and the actuating plate is disposed between the movable mirror and the peripheral supporting portion so as to be displaced due to an electrostatic force.
