英文摘要 | PURPOSE:To relax the stress to be applied to both ends of a groove, to inhibit the generation of a dark line in an active layer and to obtain a highly reliable high-output operation by forming a GaAlAs layer having a mixed crystal ratio smaller than that of a first clad layer in the groove. CONSTITUTION:An Al0.30Ga0.70As stress relaxing layer 10 is formed in such a way as to fill a groove. The mixed crystal ratio of Al to As of the layer 10 is made smaller than that of a first clad layer 3. By making the thermal expansion coefficient of the AlGaAs of the layer 10 approach to the thermal expansion coefficient of the GaAs layer, the stress to be applied to both ends of the groove 9 becomes small. An active layer 4 and a second clad layer 5 are formed in order on the clad layer 3. Thereby, the generation of a dark line in the layer 4 is inhibited and a highly reliable high-output operation can be obtained. |
