We numerically report the feasibility of generating broadband low divergent supercontinuum covering the entire wavelength window of 1.5-3.5 μm from a 2.25 m long effectively single mode all solid, soft glass based, photonic bandgap fiber with mode area as large as 1100 μm2. Owing to its chosen fabrication, friendly geometry, and the chosen material composition, the proposed fiber-based light source should be useful as a mid-wave IR pulsed broadband light source for applications such as high power delivery, optical coherence tomography and mid-IR spectroscopy. © 2013 Astro Ltd.
