Abstract
We have proposed a novel photonic crystal fibre (PCF), with three rings of air holes, that exhibit nearly zero ultra-flatted and negative chromatic dispersion, and low confinement loss at a wide telecommunication window. Key PCF fabrication parameters, such as the effects of air holes and their arrangements on the effective index, chromatic dispersion, effective mode area, non-linear coefficient and confinement losses have been analysed by use of full vectorial finite element method. Significant improvements of the PCF chromatic dispersion and confinement losses have been achieved when supplementary air holes have been incorporated.
