Abstract

PURPOSE:To perform changing over of optical fibers through the use of curving displacement of piezoelectric elements using polyvinylidene fluoride by affixing said piezoelectric elements and applying multistep voltages thereto. CONSTITUTION:The free end of a movable optical fiber 3 whose one end is fixed and other end is made free and stationary optical fibers 1, 2 are opposed with their optical axes being aligned. The free end of the fiber 3 is then moved in the + or -x axis direction to be coupled to the fiber 1 or 2. At the time of driving the fiber to accomplish this changing over, the piezoelectric elements 4A, 4B using polyvinyliden fluoride are bonded to a bimorph structure, and when electric fields are so applied that the element 4A elongates and the element 4B contracts, then the bimorph bends downward. The fiber 3 is displaced by making use of this displacement to couple the fiber 3 from 1 to 2. When the applied electric fields are made zero, the fiber 3 resets to the coupling to 1 from 2.
