Simulation study on supercontinuum generation at normal dispersion regime of a carbon disulfide core photonic crystal fiber

As a result, octave spanning of the SC spectrum was achieved in the wavelength range of near-IR from 1.25 µm to 2.3 µm with 90 fs pulse and energy of 1.5 nJ at a pump wavelength of 1.55 µm. The proposed fibers are fully compatible with all-silica fiber systems, in particular, could be used for all-fiber SC sources and new low-cost all-fiber optical systems.
