ABSTRACT:
A semiconductor laser array device comprising two or more array portions, which are composed of a plurality of main parallel waveguides with an optical phase coupling in between, and one or more branching portions, each of which is positioned between the array portions and which are composed of two branching waveguides branching symmetrically with regard to the main waveguide direction from each of the main parallel waveguides of the array portions, each of the two branching waveguides positioned at the outer sides of each of the branching portions being disconnected with the adjacent branching waveguides and the other branching waveguides from the main parallel waveguides of one of the array portions being optically connected with the corresponding branching waveguides from the main parallel waveguides of the adjacent array portion.
