Abstract
An optical switch includes an input optical fiber, first and second output optical fibers, a movable mirror for switching over an optical path between the input optical fiber and an output optical fiber, and collimator lenses disposed on optical paths formed between the input optical fiber and the output optical fibers. When drive force is applied, the movable mirror assumes a first or second position to form an optical path between the input optical fiber and the first or second output optical fiber. When drive force is not applied to the movable mirror, an optical path is formed between the optical path in the first position and that in the second position. In the first position, a first part of the movable mirror comes in contact with a substrate. In the second position, a part of the movable mirror different from the first part comes in contact with the substrate.
