英文摘要PURPOSE:To prevent decrease in laser characteristics caused by oxidation of an active layer and prevent lifetime from shortening by forming clad layers, which have lattice-matched structures with a substrate and the band gaps of which are at least 0.25eV larger than that of the active layer. CONSTITUTION:In a structure consisting of an n-type electrode 18, a GaAs substrate 17, an n-AlGaInP clad layer 16, an undoped GayIn1-yP active layer 15, a p-AlGaInP clad layer 14, etc., the layers 14 and 16 are lattice-matched with the substrate 17 and the layer 15 is made of a distorted lattice structure. The layer 15 is lattice-matched with the substrate 17 composed of (AlxGa1-x)0.5 In0.5P (0<=x<=1) and the band gaps of the layers 14 and 16 are at least 0.25eV larger than that of the layer 15. Thereby a semiconductor light-emitting device having an oscillation wavelength under 0.67mum is obtained with the layer 15 not containing aluminum and the layer 15 is hardly oxidized even at a high operation temperature because the layer 15 does not contain aluminum. Therefore, characteristics do not decrease, lifetime is lengthened, and low power consumption coherent light is obtained.
