英文摘要 | PURPOSE:To provide a semiconductor laser device which is excellent in luminous efficiency and oscillates laser rays which are prevented from shifting from a target wavelength to a shorter wavelength by a method wherein Ge is used as diffusion impurities in place of Si which requires a thermal treatment carried out at a high temperature for a long time or Zn which is hard to be controlled in diffusion length. CONSTITUTION:A semiconductor laser device is provided with an active layer 5 composed of a quantum well layer 4 of mixed crystal and barrier layers 31 and 32 provided sandwiching the quantum well layer 4 between them, Ge is thermally diffused into a part of the active layer 5 to turn the quantum well layer 4 and the barrier layers 31 and 32 at the part where Ge has been diffused into a non-luminous region 7 of mixed crystal small in refractive index through the intermediary of Ge, and on the other hand, the other part of the quantum well layer 4 and the barrier layers 31 and 32 where no Ge has been diffused is made to serve as a light emitting region 8 which functions also as a refractive index waveguide. |
