Classification: CPC H | IPC H

Claim 0:
1. A light emitting device comprising:
an epitaxial structure including a first-type semiconductor layer, an active layer, and a second-type semiconductor layer, said second-type semiconductor layer having a second-type cladding sublayer and a second-type window sublayer, said active layer being made from aluminum gallium indium phosphide (AlGaInP) and disposed on said second-type semiconductor layer, said first-type semiconductor layer being disposed on said active layer opposite to said second-type semiconductor layer, and having a first-type window sublayer and a first-type cladding sublayer that are distal from and proximate to said active layer, respectively;
a first electrode disposed on an electrode placement side of said epitaxial structure, so that said first electrode is electrically connected with said first-type semiconductor layer; and
a second electrode disposed on said electrode placement side of said epitaxial structure, so that said second electrode is electrically connected with said second-type semiconductor layer, said second electrode being in ohmic contact with said second-type window sublayer.
