英文摘要 | PURPOSE:To acquire a good semiconductor laser device of good efficiency with adequate current confinement by providing a III-V compound semiconductor layer which buries a periphery of a projecting part of a fourth clad layer above the projecting part of a III-V compound semiconductor substrate. CONSTITUTION:A pGaAs substrate 10 is provided with a pAl0.45Ga0.55As clad layer 12 which is doped with Zn only on a plane surface in a periphery of a stripe and a surface (100) of an upper surface. A p(Al0.7Ga0.3)0.5 In0.5P clad layer 14 doped with Mg all over, an undoped Ga0.5In0.5P active layer 16, and an Se-doped n(Al0.7Ga0.3)0.5In0.5P clad layer 18 are laminated in a uniform thickness. An nAl0.45Ga0.55As clad layer 20 which is doped with Zn only on a surface (100) of the clad layer 18 is formed and an undoped nAl0.45 Ga0.55As high resistance buried layer 22 is formed only on a surface (100) in a periphery of a stripe. As a result, it is possible to confine a current only in a stripe part and to acquire a semiconductor laser device of good efficiency. |
