Abstract

Summary form only given. Microcavity LEDs were optimised for optical interconnect requirements. Overall quantum efficiency of up to 4.3% into a numerical aperture of 0.5 and a FWHM beam divergence angle of 105 degrees at a drive current of 1 mA was achieved. Microcavity LEDs with one gold and one GaAs-AlAs DBR-mirror have been optimized for efficiency into a limited NA of 0.5. Simulations indicate that an efficiency of 8% can be achieved. Experimental devices give a best value of 3.7%.

微腔led的整体效率为4%，进入数值孔径为0.5

只提供摘要形式。针对光互连要求，对微腔led进行了优化。当驱动电流为1ma时，在数值孔径为0.5时，总量子效率可达4.3%，且FWHM光束发散角可达105度。具有一个金和一个GaAs-AlAs - dbr反射镜的微腔led已被优化为效率限制在0.5的NA。仿真结果表明，该方法可以达到8%的效率。实验装置给出的最佳值为3.7%。
