An optical switch device includes at least an optical switch element and driving control circuit (150). In the optical switch element, a fixed electrode portion (140) is arranged, via a dielectric layer (102), on a semi-conductor substrate (101) on which an integrated circuit is formed. A mirror structure (130, 131, 132) has a plate-shaped movable portion (131, 132) arranged above the fixed electrode portion which opposing the fixed electrode portion. A reflecting portion (131) is formed at least at part of the movable portion to reflect light. A support member (120) is fixed around the fixed electrode portion on the semiconductor substrate via a dielectric layer (102) and supports the mirror structure. The driving control circuit is incorporated in the integrated circuit to drive the optical switch element by applying a predetermined potential to the movable portion and fixed electrode portion. <IMAGE> |
