Coherent mid-infrared supercontinuum generation in tellurite all-solid microstructured optical fibers with anomalous and normal dispersion property

Abstract

Tellurite all-solid hybrid microstructured optical fibers (ASHMOFs) can be used to generate supercontinua with broad bandwidths in both anomalous and normal dispersion regimes. In the anomalous dispersion regime, a supercontinuum spectrum from 1.1 to 6.7 μm can be generated with a pump power of 10 kW and a pump wavelength of 3.5 μm. In the normal dispersion regime, a supercontinuum spectrum from 2.0 to 4.4 μm can be generated with the same pump power and wavelength. The simulations of supercontinuum generation in ASHMOFs show promising results for applications such as broadband infrared spectroscopy and enviromental monitoring. The all-solid nature of these fibers also makes them more robust and easier to handle than conventional soft-glass fibers.
