Helically twisted photonic crystal fibres
Recent theoretical and experimental work on helically twisted photonic crystal fibres (PCFs) is reviewed. Helical Bloch theory is introduced, including a new formalism based on the tight-binding approximation. It is used to explore and explain a variety of unusual effects that appear in a range of different twisted PCFs, including fibres with a single core and fibres with N cores arranged in a ...
متن کاملTensile Behavior of photonic crystal fibres
The mechanical strength and failure behavior of two photonic crystal silica optical fibers with different diameters were investigated using tensile test. The effect of polymer coating on the failure behavior was also studied. The results indicated that all fibers failed in a brittle manner and the failure normally initiated from fiber surfaces. The failure loads observed in the coated fibers ar...
متن کاملAnalysis of planewave methods for photonic crystal fibres
Photonic crystal fibres are novel optical devices that can be designed to guide light of a particular frequency. This requires two phenomena to occur. First, the frequency of light must be in a gap of the spectrum of the fibre’s cladding (usually a periodic arrangement of air holes), so that the cladding acts as a barrier to that frequency of light. Second, the perturbation or defect in the mid...
متن کاملUltimate low loss of hollow-core photonic crystal fibres.
Hollow-core photonic crystal fibres have excited interest as potential ultra-low loss telecommunications fibres because light propagates mainly in air instead of solid glass. We propose that the ultimate limit to the attenuation of such fibres is determined by surface roughness due to frozenin capillary waves. This is confirmed by measurements of the surface roughness in a HC-PCF, the angular d...
متن کاملSelective infiltration of photonic crystal fibres for waveguide arrays
Photonic crystal fibres (PCFs) can be used as a platform for the study of periodic photonic structures as well as the novel linear and nonlinear physical effects associated with them. The cladding holes in these micro-structured fibres can be infiltrated with a liquid utilising capillary action. This can be prevented in selected holes through the prior blocking of one end, producing periodic ph...
