摘要: Two kinds of fabricated hollow-core photonic crystal fibres (HC-PCFs) are studied using finite element method (FEM) because the structures of the fibres are special. Normalized transmission spectra and transverse intensity distribution of the modes are calculated and measured. And the dispersion characteristics of these two kinds of HC-PCFs were analysed from 400\,nm to 800\,nm. Simulated and measured results show that the special structure could affect the properties of HC-PCFs. By comparing the simulated values with the measured results, it can be clarified that FEM is feasible and accurate for analysing photonic crystal fibres whose structures are irregular and complex.
