Numerical analysis of photonic crystal fiber with chalcogenide core tellurite cladding composite microstructure

摘要

Kinds of photonic crystal fibers with chalcogenide core tellurite cladding composite microstructure are proposed.The multi-core photonic crystal fiber can reach the higher nonlinearity coefficient and the larger effective mode area.The small single-core photonic crystal fiber has a very high nonlinearity coefficient.At the wavelength λ =0.8 μm,the nonlinearity coefficient can reach 31.37053 W-1·m-1,at the wavelength λ =1.55 μm,the nonlinearity coefficient is 11.19686 W-1 ·m-1.
