Abstract
A semiconductor laser array device comprising an active layer, a plurality of lasing filaments for laser oscillation, a refractive-index guiding structure constituting said lasing filaments, and a striped electrode structure constituting a current path, the width of which is narrower than the overall width of said lasing filaments.
Claims3
In a semiconductor laser array device comprising a substrate and an active layer in which a plurality of lasing filaments for laser oscillation is formed by a refractive-index guiding structure, a striped electrode structure constituting a current path is formed on the top of said device, the width of said striped electrode structure being narrower than the overall width of said lasing filaments.
