| Abstract: | A monolithic white light-emitting diode (LED) with blue and yellow light active regions has been de-signed 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. |
| Keywords: | monolithic white light-emitting diode distributed Bragg reflector resonant-cavity |
