An optical switch (100) includes an input optical fiber (11), output optical fibers (18), a grating (15), which deflects a light beam from the input optical fiber (11) in different directions for each wavelength component to split into light beams, a convex lens (14), which changes the light beams from the grating (15) into converging light beams, a movable mirror array (17), which directs the converging light beams from the convex lens (14) toward one of the output optical fibers (18), a shutter array (16), disposed in front of the movable mirror array (17), and a control circuit (120), which controls the movable mirror array (17) and the shutter array (16). The movable mirror array (17) includes movable mirrors (17a), and the shutter array (16) includes the same number of shutters (16a) as that of movable mirrors (17a). The shutters (16a) appropriately intercept the light beams traveling toward the movable mirrors (17a). |
