ABSTRACT:
A semiconductor laser array device comprising an optical waveguide which is in a single mode or a multiple mode in the center portion thereof and is in a branching mode at each of both end portions thereof to form a plurality of branching waveguides which are positioned symmetrically with respect to the waveguiding direction of the laser beams and which are parallel to each other near the facets, thereby oscillating laser beams with a 0.degree.-phase shift therebetween.
