Abstract
This paper presents new results on dispersion in photonic crystal fibers (PCF) based on a circular lattice, with benzene infiltration into the hollow-core. We achieved near-zero, ultra-flat dispersion through the appropriate adjustment of air hole diameters and pitch of cladding. The result gives a dispersion of ±0.484 ps/nm-1.km over a wavelength range of 450 nm. Besides, we also obtained very high nonlinear coefficients, up to several thousand W–1.km–1, and a very low attenuation, about 10–21 dB/m for optimal structures suitable for supercontinuum generation application.
