Abstract

PURPOSE:To eliminate the change in distribution ratio owing to mode distribution within optical fibers by letting the exit light from a first optical fiber eneter across a plurality of mirrors whose reflecting faces are concave and receiving the reflected light with a plurality of optical fibers.
