Ef. Schubert et al., TEMPERATURE AND MODULATION CHARACTERISTICS OF RESONANT-CAVITY LIGHT-EMITTING-DIODES, Journal of lightwave technology, 14(7), 1996, pp. 1721-1729
Resonant-cavity light-emitting diodes (RCLED) are novel, high-efficien
cy light-emitting diodes which employ optical microcavities. These dio
des have higher intensities and higher spectral purity as compared to
conventional LED's, Analytical formulas are derived for the enhancemen
t of the spontaneous emission along the optical axis of the cavity, Th
e design rules for high-efficiency operation of RCLED's are establishe
d, The temperature dependence of the emission intensity is analyzed in
the range 20-80 degrees and it is described by an exponential depende
nce with a characteristic temperature of 112 K. The modulation charact
eristics of RCLED's exhibit 3 dB frequencies of 580 MHz. Eye diagrams
at transmission rates of 622 Mb/s are wide open indicating the suitabi
lity of RCLED's for high-speed data transmission.
