    摘要: A semiconductor light-emitting device comprises a light-emitting layer including a pn junction formed by a plurality of In.sub.x Ga.sub.y Al.sub.1-x-y P (0.ltoreq.x, y.ltoreq.1) layers, and a light-emitting-layer holding layer consisting of an indirect transition type Ga.sub.1-w Al.sub.w As (0.ltoreq.w.ltoreq.1) provided on an opposite side to a light-outputting side. The holding layer has a sufficiently small light absorption coefficient for the light from the light-emitting layer although its band gap is small and improves the light emission efficiency of the semiconductor light-emitting device.

    摘要: A semiconductor light-emitting device comprises a light-emitting layer including a pn junction formed by a plurality of In.sub.x Ga.sub.y Al.sub.l-x-y P (0.ltoreq.x, y.ltoreq.l) layers, and a light-emitting-layer holding layer consisting of an indirect transition type Ga.sub.l-w Al.sub.w As (0.ltoreq.w.ltoreq.l) provided on an opposite side to a light-outputting side. The holding layer has a sufficiently small light absorption coefficient for the light from the light-emitting layer even though its band gap is small and improves the light emission efficiency of the semiconductor light-emitting device.

    摘要: A semiconductor laser exhibiting an oscillation wavelength of 450 nm or less and comprising a substrate, a lower clad layer formed on or above the substrate and mainly composed of a III-V Group compound semiconductor, an active layer formed directly on the lower clad layer and mainly composed of a III-V Group compound semiconductor, and an upper p-type clad layer formed directly on the active layer and mainly composed of a III-V Group compound semiconductor. This semiconductor laser is characterized in that the upper p-type clad layer contains Mg, Si and at least one impurities for compensating residual donors.
