英文摘要 | PURPOSE:To lengthen lifetime within an oscillation wavelength range of 0.68-0.78mum and facilitate practical use by forming clad layers, which is lattice- matched with a GaAs substrate and the band gaps of which are at least 0.25eV larger than that of an active layer. CONSTITUTION:An n-AlGaIn clad layer 6, an undoped GaInP active layer 5, a p-AlGaIn clad layer 4, a p-GaAs ohmic contact layer 3, an insulating layer 2, and a p-type electrode 1 are formed on a GaAs substrate 7. Compositions of the layers 4 and 6 are lattice-matched with the substrate 7 and the layer 5 is composed of GayIn1-yP (0<=y<=0.5) which contain a higher rate of indium than Ga0.5In0.5P which is a lattice-matched composition. The band gaps of the clad layers 4 and 6 are at least 0.25eV larger than that of the layer 5. Laitice- unmatching of the layer 5 with the substrate 7 and regulation of band gap energy provide an oscillation wavelength of 0.68-0.78mum and the structure of the layers 4-6 facilitates manufacture, reduces size, and lowers power consumption. |
