Ultra-broadband dispersion compensating lithium-based photonic crystal fiber for mid-infrared applications

摘要

Abstract Triangular lattice-based hexagonal photonic crystal fiber (PCF) has been introduced with high negative dispersion and nonlinearity. Dispersion and nonlinearity are numerically examined by using the finite element method. A maximum negative dispersion of ??1054.73?ps/(nm?km) with a high nonlinearity of 136.44?W?1?m?1 is accomplished at 5.6?μm. The negative dispersion curve covers a broad mid-infrared range from 3.2 to 10?μm. The simulated results reveal that the reported PCF is appropriate for dispersion compensation and nonlinear optics applications such as supercontinuum spectrum, wavelength conversion, etc.
