<P>PROBLEM TO BE SOLVED: To provide an optical switch apparatus which stably operates for a long term. <P>SOLUTION: The optical switch apparatus 100 has: an input optical fiber 111 to which wave-multiplexed signal light is inputted;a plurality of output optical fibers 118 which output light; a grating 115 which deflects light beams from the input optical fiber 111 to different direction according to a wavelength element; a plurality of movable mirrors 130 which orient the light beams to each direction of the output optical fibers according to the wavelength element; a shutter 140 which appropriately cuts an optical coupling to a corresponding movable mirror 130; a tap 119 which branches a part of light which is made incident on the output optical fibers 118; a monitor PD120 which receives the light branched with the tap 119; an adjustment circuit 121 which outputs controlling values of the movable mirrors 130; a memory 122 which stores the controlling values; and a driver 123 which drives the movable mirrors on the basis of the controlling values. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
