Abstract
An optical path switching device is provided. The optical path switching device utilizes the electro-optic effect to apply an electric field on different reflective elements without moving an input/output end of optical signal or reflective elements. Thus, the reflective elements reflect optical beams to control travel paths of the optical beams, so as to switch the optical paths in the absence of mechanical motion.
