Coherent Mid-IR Supercontinuum Generation in Bismuth-Based Glass Photonic Crystal Fibers

Article Preview

Abstract:

This paper points out the properties of bismuth-based glass and the related design of photonic crystal fibers with flatted and normal group velocity dispersion profile. Supercontinuum generation in fiber is studied by a split-step Fourier numerical stimulation method. The results are shown for highly coherent mid-IR supercontinuum generation with 1.6 octaves bandwidth when pumping pulse width of 150fs and peak power of 40kW at 2.0μm. Analysis illustrates that supercontinuum generation dynamics are dominated by self-phase modulation and optical wave breaking.
