英文摘要 | PURPOSE:To perform high output, high reliability operation by a method wherein the width of the top of a mesa is wider than the bottom of the mesa, and the forbidden band width of a well layer having a quantum well structure for constituting an active layer near the end of a laser resonator is larger than that of a well layer having a quantum well structure for constituting an active layer at the center of a laser. CONSTITUTION:In order to increase the forbidden band width of a well layer having a quantum well structure near the end of a laser resonator larger than that of a well layer having a quantum well structure at the center of a semiconductor laser in the laser, an active region 250 is covered with a diffusion mask, and Zn in selectively diffused 220 into window regions 260, 270 near the end of the resonator to form window regions. A cap layer 160, a GaInP layer 150, a clad layer 130 are removed by selectively etching, and a mesa structure is formed. In order to narrow a stripe, the position of the mesa is so selected that the width of the top of the mesa is larger than that of the bottom of the mesa. |
