摘要：
A light emitting device with a coupled quantum well structure in an active region. The coupled quantum well structure may include two or more wells are separated by one or more mini-barriers, and the wells and mini-barriers together are sandwiched by barriers. The coupled quantum well structure provides almost the same effect as a wide quantum well, due to the coupling of the wavefunctions through the mini-barrier. The light emitting device may be a nonpolar, semipolar or polar (Al,Ga,In)N based light emitting device.
