摘要: Novel preforms and methods of making novel preforms are described. The preforms are suitable for being drawn into photonic bandgap optical fibres. In one form, the preform comprises a stack of elongate members having, in transverse cross section, a triangular close-packed arrangement of circular cross section capillaries, which define interstitial regions containing solid rods. The stack is supported around a relatively large capillary, which defines an inner region of the stack. The stack may be adapted by varying the number of rods in any given interstitial region, in order to generate various different configurations of cladding structure, which can be made into optical fibres having surprising operational characteristics, such as a split gap.

摘要: An optical fibre comprises: (i) a plurality of elongate, tubular, higher-refractive-index regions (20,50) of dielectric material, the regions being concentric about a longitudinal axis; (ii) a plurality of elongate, tubular lower-refractive-index regions, arranged between the higher-index regions (20,50), and comprising bridging regions (30), of a solid dielectric material, and a plurality of elongate holes (40); and (iii) a core region (10). The higher-index regions (20,50) and the lower-index regions (40) together define a cladding structure arranged to guide light in the core region (10). The elongate holes (40) are arcuate in cross-section.
