| 英文摘要 | A semiconductor laser of distributed feedback type, which is provided with a portion having periodic refractive index variations in the direction of light propagation in one of an active layer and a layer adjacent thereto and is caused to perform laser oscillation by injecting a current into the active layer portion. In accordance with the present invention, a current injection region having no periodic refractive index variations is formed on an extension of the portion having the periodic refractive index variations. |
