Comparative Study On Solid Core Photonic Crystals Fibers: Dispersion For Fixed Hole Diameter And Fixed Pitch Length

摘要

In this study, the dispersion properties of the PCFs with triangular lattice for both the udstructures with a fixed hole-diameter (d) and with a fixed pitch length (Λ) are investigated udcomparatively. The PCFs studied in this work have a core formed a missing air-hole at the udcenter in a silica background and a photonic crystal cladding with a regular triangular udlattice having 4-rings of air-holes around the core. Simulations are executed for both fixed uddiameter (d=0.84 μm) and for the fixed pitch length (Λ=4.2 μm) separately for the same udd/Λ interval from 0.1 to 0.7. It is found from the simulations that a change in Λ affects the uddispersion behavior of the PCF more dramatically relative to a change in d.
