Abstract

PURPOSE:To branch light three-dimensionally at one time, prevent decreasing of coupling efficiency and miniaturize the device by converting exit light to parallel light and branching the parallel light to a plurality of light with a polyhedral mirror and incidencing it to plural optical fibers.
