    摘要： An optical device is provided including an active layer having two outer barriers and a coupled quantum well between the two outer barriers. The coupled quantum well includes a first quantum well layer, a second quantum well layer, a third quantum well layer, a first coupling barrier between the first quantum well layer and the second quantum well layer, and a second coupling barrier between the second quantum well layer and the third quantum well layer. A thickness of the first quantum well layer and a thickness of the third quantum well layer are each different from a thickness of the second quantum well layer. Also, an energy level of the first quantum well layer and an energy level of the third quantum well layer are each different from an energy level of the second quantum well layer.
