Wideband mid-infrared supercontinuum generation in chloroform filled suspended core fiber

Abstract

In this paper we have used special feature of fiber design based on liquid-filled suspended core fiber (SCF) to observe the supercontinuum (SC) generation. Background material of this fiber is AsSe2 and three air holes are filled with chloroform (CHCl3). In liquid-filled conditions, we obtain zero dispersion wavelength at 2553 nm and the pumping wavelength is chosen at 2560 nm. From simulation results, it is demonstrated that Supercontinuum spectra from 1 μm to 14 μm could be generated by applying peak power of 10 kW and 50 fs pulse duration at 2560 nm. Moreover, a comparison between liquid-filled SCF and standard SCF in the broadening of SC spectra is analyzed and discussed.
