Abstract
A new design of a triangular-core photonic crystal fiber in As2Se3-based chalcogenide glass with all-normal, nearly zero flat-top dispersion has been proposed for supercontinuum generation. Simulated results indicate that ultra-broadband supercontinuum spanning 1.9-10 µm can be obtained using only 6 mm long PCF pumped with 50 femto-second laser pulses operated at 4.5 µm. In comparison to previously reported work we have obtained ultra-broadband supercontinuum spectra using relatively very low peak power of incident pulses. Proposed photonic crystal fiber structure is applicable in bio-molecular sensing and infrared spectroscopy.
