We present numerical results of supercontinuum (SC) generation in the mid-IR\nspectral region, specifically addressing the molecular fingerprint window\nranging from 2.5 to 25 um. By solving the Generalized Nonlinear Schr "odinger\nEquation (GNLSE) in a chalcogenide waveguide, we demonstrate low-power SC\ngeneration beyond 10 um from a pump at 5 um. Further, we investigate the\nshort-pulse and CW regimes, and show that a simple linear dispersion profile,\napplicable to a broad range of chalcogenide media, is sufficient to account for\nthe broad SC generation, and yield rich pulse dynamics leading to the frequent\noccurrence of rogue wave events. Results are encouraging as they point to the\nfeasibility of producing bright and coherent light, by means of single\nlow-power tabletop laser pumping schemes, in a spectral region that finds\napplications in such diverse areas as molecular spectroscopy, metrology and\ntomography, among others, and that is not easily addressable with other light\nsources\n
