英文摘要 | PURPOSE:To prevent a formation at two points of light-emitting spots, and to obtain a stable transverse mode by forming a striped groove to a V shape. CONSTITUTION:A striped groove, which reaches the inside of a second clad layer 4 from the surface of a current constriction layer 5 and is formed, is shaped to a V form. Consequently, an oscillating threshold can be lowered, and not only characteristics fit for an optical-disk light source such as the improvement of the circle of beams and the reduction of astigmatism are obtained but also a stable fundamental transverse mode is acquired because of the V-shaped striped groove. That is, there is only one position of a corner section where the film thickness of a high refractive-index layer 6 is thickened on the growth of the layer 6 in the V-shaped striped groove. As a result, beams are wave-guided only at one position of the corner section. Accordingly, beams are not wave-guided at two positions as seen in conventional devices and do not emit light, thus acquiring laser beams at the stable transverse mode. |
