Paper Abstract

A novel concept has been developed for a fiber optic switch. It is based on miniaturized prisms deflecting the nearly collimated beam from the input fiber. These prisms are moved by the use of piezoelectric bending actuators. The deflected beam is directed to the output fiber, there is one prism for each output fiber. Coupling of the deflected light beam into the output fibers is achieved by microlenses. In order to simplify the integration process regular arrays of both the output fibers and the coupling microlenses have been used. A special technique and setup has been developed for fast and accurate adjustment of the lens array with respect to the fiber array. Both arrays are subsequently fixe to each other by gluing. The second critical integration process is the mounting procedure of the prisms to the bending actuators. For this purpose a special vacuum gripper has been built. With the help of this gripper all microprism can be mounted in one step. Using the developed integration processes, fiber switch prototypes have been built up with excellent optical parameters.
