Supercontinuum generation in the novel semiconductor doped dispersion decreasing fiber
A theoretical study of modulational instability (MI) in the semiconductor doped dispersion decreasing (SD-DDF) fiber is presented. We consider the combination of saturation of nonlinear response (SNL) and the dispersion decreasing fiber (DDF). The two extreme physical effects considered lead to exciting outcome, where decreasing dispersion leads to broadening the spectral width and saturation on the other hand suppresses the bandwidth. We proposed that instead of using DDF whose bandwidth is limited by the manufacturing constraints, the use of SD-DDF offers better tailoring of the bandwidth profile by suitably altering the power.
