Abstract:
1. An optical switch comprising: at least one input optical fiber; output optical fibers; at least one movable mirror having a reflective surface, which directs a light beam from the input optical fiber selectively to one of the output optical fibers, an angle of the reflective surface of the movable mirror being changeable, and the angle of the reflective surface of the movable mirror being changed to switch the output optical fiber that combines with the light beam reflected by the movable mirror; and at least one shutter, which appropriately intercepts the light beam traveling toward the reflective surface of the movable mirror from the input optical fiber, the shutter intercepting the light beam traveling toward the reflective surface of the movable mirror while the angle of the reflective surface of the movable mirror is changed; and input optical fibers including the input optical fiber, and at least one movable mirror array, wherein each movable mirror array includes the same number of movable mirrors as that of the input optical fibers, and the movable mirrors of each movable mirror array handle light beams from the input optical fibers.
