Abstract :
We theoretically demonstrate a white light LED structure containing a one-dimensional photonic crystal which is designed by realistic fabrication parameters for the formation of omnidirectional photonic band gaps. With a band gap around 370 nm, such a novel structure could completely trap the desired UV light inside the LED array and let the visible light pass through.
