PROBLEM TO BE SOLVED: To provide an optical switch which does not cause crosstalks to be generated for an output optical fiber upon switching operation. SOLUTION: The optical switch 100 has an input optical fiber 11, a plural number of output optical fibers 18, a grating 15 that deflects the optical beam from the input optical fiber 11 into different directions for each wavelength component, a convex lens 14 that changes the optical beam from the grating 15 into a convergent optical beam, a movable mirror array 17 which directs the convergent optical beam from the convex lens 14 to one of the plurality of output optical fibers 18, a shutter array 16 arranged in front of the movable mirror array 17 and a control circuit 120 that controls the movable mirror array 17 and the shutter array 16. The movable mirror array 17 has a plurality of movable mirrors 17a, and the shutter array 16 has the same number of shutters 16a as that of the movable mirrors 17a. The shutter 16a properly intercepts the light beam traveling toward the movable mirrors 17a. COPYRIGHT: (C)2005,JPO&NCIPI |
