Supercontinuum Generation at 3100 nm in Dispersion-Engineered As_(38.8)Se_(61.2)-Based Chalcogenide Photonic Crystal Fibers

摘要

The presented paper numerically investigates the mid-infrared supercontinuum generation of 3800 nm broad spectra spanning from 2000 to 5800 nm with nonlinear As_(38.8)Se_(61.2) chalcogenide solid core photonic crystal fiber. The photonic crystal fiber is tailored to generate dispersion in anomalous region, resulting in zero-dispersion wavelengths. Pumping the engineered fiber with 1 kW power at 3100 nm near lower zero-dispersion wavelength a broad spectrum is observed.
