Numerical investigation on coherent mid-infrared supercontinuum generation in chalcogenide PCFs with near-zero flattened all-normal dispersion profiles |
(a) Simulated spectral evolution, (b) simulated spectral output, (c) simulated spectrogram, and (d) modulus of complex degree of first-order coherence of the output SC, with 3-cm chalcogenide PCF pumped at |
