摘要： In order to provide a small-sized and compact optical switch of 1×4 type. Two movable optical fibers are fixed on a substrate by a fixing block disposed in a middle portion of the fibers. Two movable blocks made of a soft magnetic body are mounted to the both ends of the movable optical fibers. Two soft magnetic fixing blocks are arranged on the substrate for fixing one optical fiber so as to oppose to one of the movable block, and for fixing four optical fibers so as to oppose to the movable block, respectively. Two movable blocks can be independently moved with respect to the respective fixing blocks by means of actuators. Further, it is possible to detect a position of each movable block with respect to the fixing block by means of detecting electrodes.
