| 英文摘要 | A semiconductor laser device is disclosed, in which two semiconductor layers of different conduction types are formed on a semiconductor substrate, an active semiconductor layer having a forbidden band width narrower than the two semiconductor layers is formed between the two semiconductor layers, and a waveguide encloses the light in a plane parallel to the active layer. The waveguide includes at least two regions of different widths. The wider one of the waveguide regions is located in the vicinity of the end surface of the semiconductor laser. A relation holds that pi /6 |
