| Abstract: | Two kinds of fabricated hollow-core photonic crystal fibres(HC-PCFs) are studied using finite element method (FEM) because thestructures of the fibres are special. Normalized transmissionspectra and transverse intensity distribution of the modes arecalculated and measured. And the dispersion characteristics of thesetwo kinds of HC-PCFs were analysed from 400,nm to 800,nm.Simulated and measured results show that the special structure couldaffect the properties of HC-PCFs. By comparing the simulated valueswith the measured results, it can be clarified that FEM is feasibleand accurate for analysing photonic crystal fibres whose structuresare irregular and complex. |
