Abstract:
A semiconductor light-emitting device comprising:a semiconductor substrate, at least first and second reflecting multilayers, a light-emitting layer, and wherein the first and second reflecting multilayers are formed on the semiconductor substrate by use of at least two material systems having a variable refractive index, and having a lattice constant similar to that of the semiconductor substrate, and each of the reflecting multilayers being formed by depositing alternatively two types of layers of the same material system; and wherein the light-emitting layer is formed on the plurality of reflecting multilayers so that both the first and second reflecting multilayers are on the same side of the light-emitting layer, wherein the light-emitting layer comprises one or more Layers including an active layer comprising the same material system as that of an uppermost of the reflecting multilayers, and wherein the uppermost reflecting multilayer is in contact with said light-emitting layer.
