| Research Abstract |
We studied the supercontinuum light covering the visible to mid-infrared wavelength region using chalcogenide glasses with highest nonlinearity among the glasses and fluoride glasses with high transparency from the ultra-violet to mid-infrared region in this project. We clarified the composite microstructure which can control the chromatic dispersion of chalcogenide fibers. We have clarified the Raman response of these glasses and analyzed supercontinuum generation in the micro-structured fibers using non-linear Schrodinger equation. We obtained the widest supercontinuum light from 0.35μm to 6.2μm. Based on these experimental and theoretical results, we clarified that chalcogenide composite microstructured fiber we developed can generate the supercontinuum light from the visible to mid-infrared region.
