Zg. Lu et al., Frequency comb generation by cascade cavity-enhanced four-wave mixing in asemiconductor optical amplifier, MICROW OPT, 23(3), 1999, pp. 134-137
The generation of a frequency comb of optical signals with equal frequency
spacing has been demonstrated in a semiconductor-fiber ring laser. A simpli
fied theoretical approach bused on cascade cavity-enhanced four-wave mixing
in a semiconductor optical amplifier is given, and potential applications
are described. (C) 1999 John Wiley & Sons, Inc.*.
