In an AlGaInP type semiconductor light-emitting device, an n-type AlGaInP cladding layer and a p-type AlGaInP cladding layer are deposited so as to interpose an active layer made of GaInP or AlGaInP therebetween. Light guiding layers are provided between the active layer and the n-type cladding layer, and/or, between the active layer and the p-type cladding layer, respectively. The p-type cladding layer is doped with Be serving as a p-type dopant. The active layer, the p-type cladding layer and the light guiding layers are doped with Si which may serve as an n-type dopant. <IMAGE> |
