Abstract

Due to the large scientific and technical interest in the mid-infrared (MIR) spectral region, and the limitations of MIR light sources, we focus on the generation of a broad supercontinuum inside a short piece of ${\mathrm{As}}_2{\mathrm{Se}}_3$ microstructured optical fiber (MOF) with a square lattice. This is accomplished by filling the holes in the innermost ring of the proposed MOF with ${\mathrm{Ge}}_{33}{\mathrm{As}}_{12}{\mathrm{Se}}_{55}$ to produce ultraflat and near-zero dispersion. Simulations reveal that, by launching 100 fs input pulses centered at ${\lambda }_0=6.2\mathrm{\mu m}$ with a peak power of 2 kW into the MOF, an optical spectrum as wide as 9.5 μm will be achieved. This spectrum is a suitable source for MIR applications such as spectroscopy, food quality control, and gas sensing.
