Monolithic white LED based on AlxGaN1-x/InyGa1-yN DBR resonant-cavity
|
Abstract:
A monolithic white light-emitting diode (LED) with blue and yellow light active regions has been designed and studied. With the AlGaN/InGaN distributed Bragg reflector (DBR) resonant-cavity, the extraction efficiency and power of the yellow light are enhanced so that high quality white light can be obtained.
