Abstract
A group III-V light-emitting diode is provided. The light-emitting diode includes a light generating portion including an active layer interposed between a first conductivity type semiconductor layer and a second conductivity type semiconductor layer. The active layer generates light. The light-emitting diode further includes an optical trap disposed on an optical path of light generated from the active layer. The optical trap includes a light absorption layer interposed between light guide layers. The light-emitting diode further includes a side reflector disposed on a side surface of the optical trap.
