Mid-IR supercontinuum generation in an integrated liquid-core optical fiber filled with CS sub(2)

We report supercontinuum generation in a 16cm long integrated liquid-core optical fiber (LCOF) filled with neat carbon disulfide (CS sub(2)). The LCOF was pumped with compact mode-locked fiber lasers operating near 1560nm and 191 Onm. The supercontinuum spanned from 1460nm to 2100nm and from 1790nm to 2400nm at 20 dB level for 1560nm and 191 Onm pump wavelengths, respectively. The spectral broadening extended mostly to longer wavelengths due to the high Raman contribution to the nonlinear optical response of CS sub(2). The experimental results are in good agreement with numerical simulations.
