摘要: On an n-type GaAs semiconductor substrate, an n-type cladding layer formed of AlGaInP system crystal almost in lattice matching with the semiconductor substrate, an active layer and a p-type cladding layer formed of AlGaInP system crystal almost in lattice matching with the semiconductor substrate are formed, and a p-type barrier cladding layer formed of AlGaInP system crystal or AlInP system crystal is provided in the p-type cladding layer. The p-type barrier cladding layer has a thickness through which electrons are almost not transmitted, has tensile strain, and also has band gap energy larger than that of the p-type cladding layer.
