Photonic crystal fibres
This is a dataset of Finite Difference Time Domain (FDTD) simulation results of 13 defective crystals and one non-defective crystal. There are 4 fields in the dataset, namely: Real, Img, Int, and Attribute. The header real shows a real part of the simulated result, img shows the imaginary part, int gives the intensity all in superimposed form. Attribute denotes the label of a crystal simulated. The label 0 is for the simulated crystal, which is non-defective. Other 13 labels, from crystal 1 to crystal 13 are assigned to the 13 different crystals whose simulations are studied.

The impact of drawing parameters on the structure of solid-core axisymmetric structured optical fibres (SOF) stacked to form four hexagonal rings of air-holes is investigated. The modelling of the internal capillary structure on optical fibre drawing using an unconstrained applied internal pressure in analogous single-capillary is contested. A corrected single-capillary function to cater for multi-capillary structural constraint within a larger single capillary draw, whilst retaining analytical simplicity, is proposed and shown to give reasonable and meaningful fits with experiments.
