摘要
提出并研究了一种基于表面微腔光子晶体的发光二极管(LED), 利用多个谐振腔出射光之间的相干耦合作用产生束流准直效应, 从而在提高光提取效率的同时, 也改善了出射光的空间指向性。通过对表面光子晶体LED结构进行优化设计, 使得表面微腔光子晶体LED的光提取效率较完整光子晶体LED提高了77.3%, 而较普通平板LED提高了1.8倍以上。同时, 微腔光子晶体LED相对普通平板LED和完整光子晶体LED来说具有更加明显的远场能量汇聚效应, 让出射光具有更好的空间指向性。
Abstract
In this paper, we propose and study a light-emitting diode (LED) based on the surface-microcavity photonic crystal (PC). The beaming-collimation effect is generated by the coherent-coupling interaction of the emergent light from the multiple resonant cavities. As a result, the light extraction efficiency of LED is improved, as well as the spatial directivity of emergent light. By optimizing the structure of the surface PC LED, the light extraction efficiency of the surface-microcavity PC LED is 77.3% higher than that of the prefect PC LED, and 1.8 times higher than that of the normal slab LED. Simultaneously, the proposed surface-microcavity PC LED has more obvious far-field energy converging effect than prefect PC LED and normal slab LED. This feature ensures the emergent light with better spatial directivity.
