摘要

We investigate numerically supercontinuum generation (SCG) pumped by different optical modes in AsSe_2-As_2S_5 chalcogenide microstructured optical fibers (MOFs). The influence on SCG is analyzed numerically by different optical modes including the fundamental and high-order modes. We simulate and analyze the evolution of the supercontinuum (SC) at different pump wavelengths (2120 nm, 2580 nm and 3280 nm) and different optical modes (LP_(01), LP_(11), LP_(31)). The pump peak power is from 200 to 1000 W in the MOFs with different core diameters. We also simulate the evolution of SCG with the fiber length. The different optical modes cause the variation of the chromatic dispersion profile and the effective nonlinearity, which induces different mechanisms of the SCG and changes the spectral range. For the LP_(01) mode, the simulated maximum SC spectral range covers 10.375 urn from 1.875 to 12.250 um when pumped at 3280 nm with the peak power of 1000 W. For the LP_(11) mode, the maximum SC spectral range is obtained when pumped at 3280 nm with the peak power of 1000 W, which covers 12.931 μm from 1.389 to 14.320 μm. For the LP_(31) mode, the maximum SC spectral range is from 1.267 to 3.980 μm when pumped at 2120 nm with the peak power of 1000 W. The widest SC spectral range is obtained when pumped by the LP_(11) mode. The simulated results will be instructive for the experimental SCG up to the mid-infrared waveband longer than 10 μm.
