Abstract
A light emitting device may include a first conductive semiconductor layer, an active layer adjacent to the first conductive semiconductor layer and a second conductive semiconductor layer adjacent to the active layer. The active layer may include a first quantum well layer, a second quantum well layer and a barrier layer between the first quantum well layer and the second quantum well layer. The first quantum well layer may include a first plurality of sub-barrier layers and a first plurality of sub-quantum well layers, and the second quantum well layer may include a second plurality of sub-barrier layers and a second plurality of sub-quantum well layers. A bandgap of the first quantum well layer may be different than a bandgap of the second quantum well layer.
