ABSTRACT:
A semiconductor light-emitting device according to the present invention is made by forming an undoped In.sub.1-X Ga.sub.X As.sub.1-Y P.sub.Y active layer on a n-InP clad layer, a p-In.sub.1-X Ga.sub.X As.sub.1-Y P.sub.Y active layer on said undoped active layer, and a p-n junction position in the interface between said n-InP layer and said undoped In.sub.1-X Ga.sub.X As.sub.1-Y P.sub.Y active layer or in the neighborhood thereof. By this structure, the heretofore inevitable problem of remote junction can be solved and the half value width of the light-emitting spectrum can be reduced. Therefore, the semiconductor light-emitting device according to the present invention provides higher response frequency and larger light-emitting output than the conventional semiconductor light-emitting device.
