文摘A monolithic white light-emitting diode （LED） with blue and yellow light active regions has been designed and studied. With the AlxGa1-xN/InyGa1-yN 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.
