Mid-infrared supercontinuum generation in a three-hole Ge 20 Sb 15 Se 65 chalcogenide suspended-core fiber

Highly coherent mid-infrared supercontinuum generations in a strip titanium dioxide waveguide with three zero-dispersion wavelengths

“…It is reported that the MIR SC spanning from 1.4 to 13.3 μm was obtained in a soft-glass optical fiber using the pump pulse with a peak power of 2.29 MW and central wavelength of 6.3 μm 12 . In 2017, Han et al 13 . fabricated a chalcogenide suspended-core optical fiber and generated an SC with a spectral width of 2 to 8 μm.…”

Effects of pressurization and surface tension on drawing Ge-Sb-Se chalcogenide glass suspended-core fiber

“…To achieve this, a suitable geometry with small suspended-core size and thin bridges is required. Conventional fabrication methods such as extrusion [9], ultrasonic drilling [10], casting [11], or stack-and-draw [12] have been used to produce suspended-core fiber preforms. Normally, pressurization is introduced in the final step of the fiber drawing process to expand hole sizes and reduce bridge thicknesses.…”

Infrared supercontinuum generated in concatenated InF3 and As2Se3 fibers

“…As shown in Table 1, there have been several demonstrations of infrared SC generation with ChG fibers [14,17,18,[23][24][25][26][27][28][29][30] and some of them stand out by their output powers or their spectral bandwidths. The proper optical material for the conception of a ruggedized multi-watt SC source in the infrared is explored intensively by many research groups, and recent progresses in laser and fiber technologies indicate that such objectives should be reached in a near future.…”

“…A lot of effort has gone into producing high purity fibers in order to decrease the detrimental effects of contaminant absorption on SC broadening. Such improvements of the fluoride and ChG transmission allowed the generation of ultrabroadband SC in these fibers [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][23][24][25][26][27][28][29].…”
