英文摘要 | PURPOSE:To obtain a semiconductor laser of small noises and small astigmatism by a method wherein a light is wave-guided by a gain guide at the center of an active layer, thus oscillated by multi-modes, and a wave surface bent at the center is corrected in the neighborhood of two end surfaces. CONSTITUTION:The active layer 13 one of continuous semiconductor layers is flat and has a uniform thickness in the direction crossing the longitudinal direction of a stripe electrode 3 which connects the two end surfaces 4 and 5, and then bent in the direction crossing the longitudinal direction of the electrode 3 in the neighborhood of the surfaces 4 and 5. The thickness of the electrode 3 at the center is formed thicker than those of both edges, and the light is wave- guided along the thick part of the layer 13 at the center of the layer, resulting in the oscillation of the multi-modes. Besides, in the neighborhood of the surfaces 4 and 5, the wave surface bent at the center is corrected by making the distribution of refractive indices reverse to that at the center. Thereby, the semiconductor laser which restrains the increase of noises accompanied with the variations of temperature or current and has the small astigmatism can be obtained. |
