Fresnel Fibres with Omnidirectional Zone Cross-sections
Abstract:
Fresnel fibres with silica zones resembling omnidirectional structures with self-imaging properties are proposed. Numerical simulation is carried out on a large air hole Fresnel fibre with a triadic Cantor fractal zone cross-section (FZC). The results show the transmission bandgap of these fibres widens and the practical confinement loss decreases with increasing orders of self-imaging. For an order of S = 4 a bandwidth Deltalambda= 0.69 mum and a confinement loss of 0.11 dB/km @ 1.1 mum is calculated.
