Paper Abstract

Supercontinuum (SC) generation in six core hexagonal lattice photonic crystal fiber (PCF) made of As2Se3-based chalcogenide glass was numerically investigated. The fiber was excited by 50 fs input pulse with hyperbolic secant field profile with tunability range of 2.5-5.5 μm. We obtained a flat-top normal dispersion profile when choosing Λ=1 μm and d=0.9 μm. By pumping near the zero dispersion wavelength, a high coherent SC spanning over 4 μm was generated with a launched pulse energy of E= 100 pJ in only 1 cm fiber length. The generated SC is therefore ideal for applications in ultrafast science, metrology, coherent control, non-destructive testing, spectroscopy, and optical coherence tomography in the mid-infrared region.
