AB A common issue in fiber-based supercontinuum (SC) generation undercontinuous-wave pumping is that the spectral width of the resulting source is relatedto the input power of the pump laser used. An increase of the input pump powerleads to an increase of the spectral width obtained at the fiber output, and therefore,the average power spectral density (APSD) over the SC spectrum does not growaccording to the input power. For some applications it would be desired to have afixed spectral width in the SC and to increase the average PSD proportionally to theinput pump power. In this paper we demonstrate experimentally that SC generationunder continuous-wave (CW) pumping can be spectrally bounded by using a fiberwith two zero-dispersion wavelengths (ZDWs). Beyond a certain pump power, thespectral width of the SC source remains fixed, and the APSD of the SC grows withthe pump power. In our experiment we generate a reasonably flat, spectrally-boundedSC spanning from 1550 nm to 1700 nm. The spectral width of the source is shown tobe constant between 3 and 6 W of pump power. Over this range, the increase in inputpower is directly translated in an increase in the output APSD. The experimentalresults are confirmed by numerical simulations, which also highlight the sensitivityof this configuration to variations in the fiber dispersion curve. We believe that theseresults open the way for tailoring the spectral width of high-APSD CW SC byadjusting the fiber dispersion.
