US 8,803,178 B2 · Light emitting diode

Abstract

A light emitting diode includes a substrate, a source layer, a metallic plasma generating layer, a first optical symmetric layer, a second optical symmetric layer, a first electrode, and a second electrode. The source layer includes a first semiconductor layer, an active layer, and a second semiconductor layer stacked on a surface of the substrate in series. The first electrode is electrically connected with the first semiconductor layer. The second electrode is electrically connected with the second semiconductor layer. The metallic plasma generating layer is disposed on a surface of the source layer away from the substrate. The first optical symmetric layer is disposed on a surface of the metallic plasma generating layer away from the substrate. The second optical symmetric layer is disposed on a surface of the first optical symmetric layer away from the substrate.
