Impact of the self steepening effect on soliton spectral tunneling in PCF with t

This work presents a numerical investigation of the self-steepening (SS) effect on the soliton spectral tunneling (SST) effect in a photonic crystal fiber (PCF) with three zero dispersion wavelengths. Interestingly, the spectral range and flatness can be flexibly tuned by adjusting the SS value. Whe
