Abstract
Photonic bandgap fibres fabricated by infiltrating the holes of a microstructured optical fibre with high-index material are investigated numerically in the low- and intermediate-frequency regime. Bandgaps, transmission windows and the distribution of field energy between high- and low-index regions are investigated. It is shown that the numerical results found can be rationalized in a simple way by considering the properties of guided modes in a conventional step-index fibre.
