Abstract

In a semiconductor laser having a ridge-shaped stripe and made of nitride III-V compound semiconductors, opposite sides of the ridge are buried with a buried semiconductor layer of AlxGa1-xAs (0<&times;&lE;1), (AlxGa1-x)yIn1-yP (0&lE;&times;&lE;1, 0&lE;y&lE;1) or ZnxMg1-xSySe1-y (0&lE;&times;&lE;1, 0&lE;y&lE;1) to stably control transverse modes, thereby minimizing higher mode oscillation during a high power output, and improving the heat dissipation property.
