Numerical investigation on broadband mid-infrared supercontinuum generation in chalcogenide suspended-core fibers

Abstract: As 2 S 3 and As 2 Se 3 chalcogenide 3-bridges suspended-core fibers (SCFs) are designed with shifted zero-dispersion wavelengths (ZDWs) at around 1.5 µm, 2 µm, and 2.8 µm, respectively. A generalized nonlinear Schrödinger equation is used to numerically compare supercontinuum (SC) generation in these SCFs pumped at an anomalous dispersion region nearby their ZDWs. Evolutions of the long-wavelength edge (LWE), the power proportion in the long-wavelength region (PPL), and spectral flatness (SF) are calculated an… Show more
