The Dispersive and Nonlinear Properties of Photonic Crystal Fibers with Modified Honeycomb Lattice Structure
Photonic crystal fibers with modified honeycomb lattice structure were proposed by combining the advantages of honeycomb lattice and lattice with different air-hole diameters. The dispersive and nonlinear properties of the proposed fibers
which formed by different structural parameters
are numerically simulated by using the vectorial beam propagation method
and the relationship of dispersion
nonlinear coefficient with the lattice structure was investigated. The results indicate that the distinct dispersive properties
which contain large negative dispersion
flattened dispersion
positive dispersion
and so on are achieved in the wavelength range of 1.2~1.6 m. Furthermore
the decrease of the diameters of air-holes in the lattice structure leads to an increase of effective area in fundamental mode which make the nonlinear coefficient lower. Thus the dispersive and nonlinear properties of the proposed fiber can be flexibly tailored by adjusting its structural parameters. This provides a reference for designing novel photonic crystal fibers.
