The RC2LED: a novel resonant-cavity LED design using asymmetric resonant cavity in the outcoupling reflector

摘要

We present the concept of a novel resonant-cavity LED design wherena symmetric resonant cavity (RC) is added to the outcoupling reflector.nBecause of the peculiar characteristics of the resulting mirror, thesenso-called RC2LED's have a much higher extraction efficiencyninto a limited NA as compared to conventional RCLED designs
