Abstract:
A surface-light-emitting device comprising:a semiconductor substrate; and a laminar semiconductor structure having a plurality of semiconductor layers formed by epitaxial growth on said semiconductor substrate, said laminar semiconductor structure including, a light-generating layer, and two multi-film reflecting layers between which said light-generating layer is interposed and which comprise a light resonator configured to reflect a light generated by said light-generating layer, said laminar semiconductor structure having a light-emitting surface at one of opposite ends thereof remote from said semiconductor substrate, said light generated by said light-generating layer being emitted from said light-emitting surface, said two-multi-film reflecting layers having a first multi-film reflecting layer formed principally of AlGaInP on said semiconductor substrate, and a second multi-film reflecting layer formed principally of AlGaAs on one of opposite sides of said light-generating layer which is remote from said semiconductor substrate, and said light-generating layer including at lease one active layer interposed between adjacent two barrier layers, each of said at least one active layer being formed of a GaInP monocrystalline compound semiconductor layer.
