Mid-infrared supercontinuum generation (SCG) is mostly studied in fluoride glass fibers in which long fibers and high power pump sources are needed. Taking advantages of high nonlinearity and transparency, chalcogenide glass is also applied for SCG in mid-infrared region, where specific strategy is needed to compensate large normal material dispersion. Researchers at Key Laboratory of Materials for High Power Laser, Shanghai Institute of Optics and Fine Mechanics,investigate multimaterial fibers (MMFs) combined with fluoride and chalcogenide glasses for SCG. The high refraction contrast allows the zero dispersion point of the fiber to shift to below 2 μm without air holes. These two materials have similar glass transition temperatures and thermal expansion coefficients. They are possible to be drawn together. Both stepindex MMFs and microstructured MMFs (MS-MMFs) are considered. The chromatic dispersions and supercontinuum spectra are studied. A 20 dB bandwidth of over one octave SCG with high coherence can be obtained from a 1 cm MS-MMF at 1.95 μm with a pumping peak power of 175 W.As the pump power increased, the spectrum can extend to 5 μm. In this scheme the fiber is so short that the high level of loss, which is the feature of MMFs, will not cause problems.[OPTICS EXPRESS.22,20,24179(2014)]
