photonic crystal fiber with a hollow core filled with carbon disulfide (CS2 is proposed as a new source of supercontinuum light. We numerically study guiding properties of modeled fibers including the dispersion and the effective mode area of the fundamental mode. As a result, octave spanning of the SC spectrum was achieved in the wavelength range of near-IR from 1.25 mm to 2.3 mm with 90 fs pulse and energy of 1.5 nJ at a pump wavelength of 1:55 mm. 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
