Abstract
LED structures with the introducing of surface PC and planer micro cavity was described to improve the light extraction efficiency of LEDs. The distributions of guided modes propagated in LED were analyzed, and the modal extraction lengths were determined using high-resolution angle-resolved measurements in order to research the interaction of each guided mode with PCs. The impact of structure parameters design on modal extraction length was learned. Result shows that PC extraction will not interfere with micro cavity effects, and can be used together to enhance LEE.
