M. Saarinen et al., Resonant-cavity light-emitting diodes operating at 655 nm with a high external quantum efficiency and light power, IEEE PHOTON, 13(1), 2001, pp. 10-12
Monolithic resonant cavity light-emitting diodes exhibiting an external qua
ntum efficiency (eta (ex)) up to 6.5% for 84-mum size devices at a waveleng
th of 655 nm have been demonstrated. Larger diodes, 150-300 mum in diameter
, have the maximum eta (ex) between 5.5% and 4.9% and launch power output u
p to 8 mW.
