ABSTRACT:
Each of guided beam incident portions of an optical waveguide device includes a straight incidence area where laser beams enter, a curved area which curves the laser beams entering from the straight incidence area in a predetermined direction, and a widening tapered area which makes the laser beams that have passed through the curved area parallel or substantially parallel to a propagation direction of the laser beams by decreasing propagation angles of the laser beams.
