Abstract
This paper analyses the advantageous features of supercontinuum (SC) generated from continuous-wave (CW)
excitation. It has been shown that both the generation mechanisms and the temporal and spectral properties of
supercontinuum produced with CW pump lasers are different from those of generated by means of pulsed excitation, in
particular the remarkable smoothness of CW-SC spectra. We show that these unique spectral features stem from the
fission of the partially coherent CW input beam into a train of subpicosecond pulses induced by the modulation
instability (MI). These subpicosecond pulses lead to the formation of optical solitons with inherently random parameters,
which self-frequency shift differently depending on their characteristics. The resulting supercontinuum spectrum is hence
the average of many different soliton spectra, which have suffered different frequency shifts. Different experimental
setups used in our lab are presented and the dependence of the SC generation on the coherence of the fiber laser and the
fiber dispersion profile are shown.
