英文摘要 | PURPOSE:To obtain a high performance semiconductor laser device which has high quality InGaAlP/GaAs heterojunctions, a short wavelength and a long life by a method wherein a 1st conductivity type cladding layer or 2nd conductivity type cladding layers are doped with Si. CONSTITUTION:In a semiconductor laser device, double-heterojunction structures 14-18 composed of InxGa1-x-yAlyP layers (0<=y<=1) are formed on a 1st conductivity type GaAs substrate 1 the first conductivity type cladding layer 14 or second conductivity type cladding layers 16 and 18 of the semiconductor laser device are doped with Si. For instance, an Si-doped n-type GaAs buffer layer 12 and an Si-doped n-type InGaP buffer layer 13 are formed on the n-type GaAs substrate 1 Then the double-heterojunction structures composed of the Si-doped n-type InAlP cladding layer 14, the In0.5Ga0.5P active layer 15 and the Mg-doped p-type InAlP cladding layers 16-18 are formed on the buffer layer 13. Further, a p-type InGaAlP contact layer 19, a p-type GaAs layer 20, an Se-doped n-type GaAlAs current blocking layer 21 and so forth are provided. |
