P. Bienstman et R. Baets, The (RCLED)-L-2: A novel resonant-cavity LED design using a symmetric resonant cavity in the outcoupling reflector, IEEE J Q EL, 36(6), 2000, pp. 669-673
We present the concept of a novel resonant-cavity LED design where a symmet
ric resonant cavity (RC) is added to the outcoupling reflector. Because of
the peculiar characteristics of the resulting mirror, these so-called RC2 L
ED's have a much higher extraction efficiency into a Limited NA as compared
to conventional RCLED designs.
