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 (1000) comprises a stack of elongate members comprising, in transverse cross section, a triangular close-packed arrangement of circular cross section capillaries (1020), which define interstitial regions containing solid rods (1040). The stack is supported around a relatively large capillary (1030), 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 bandgap.

摘要： The present invention is in the field of optical fibres. In particular, the present inventors describe hollow core optical fibres, for example hollow core photonic band-gap optical fibres. The present inventors describe examples of such fibres that guide light by virtue of a true photonic band-gap in a hollow core region having a boundary at the interface between the hollow core and a photonic band-gap cladding. In some examples, the boundary is tuned by addition of solid material during formation of a respective fibre preform (1800) to improve the performance of the resulting fibre, for example by mitigating deleterious effects such as mode coupling of light from core-guided modes to so-called boundary or `surface' modes.

摘要： Fluid analysis may be achieved according to embodiments of the present invention by introducing a water-based analyte into a hollow core region (1000) of a photonic crystal waveguide, for example a photonic crystal fibre, acting as a liquid core waveguide. The waveguide has, around the core region, a microstructured cladding region (1020), which comprises a silica matrix (1060) filled with a periodic array of air holes (1040). The waveguide is able to guide a wide range of wavelengths of light, including excitation and sensing wavelengths of light, through the analyte by total internal reflection in the core region. This is possible because the cladding region of a photonic crystal waveguide can be arranged to have an effective refractive index lower than water, even though silica has a refractive index higher than water. Many other analytes, with even lower refractive indices than water, may be tested according to other embodiments of the present invention.
摘要翻译：通过将水基分析物引入光子晶体波导（例如用作液芯波导的光子晶体光纤）的中空芯区域（1000）中，可以实现根据本发明实施例的流体分析。波导具有围绕芯区域的微结构化包层区域（1020），其包括填充有周期性阵列的空气孔（1040）的二氧化硅基质（1060）。波导能够通过核心区域中的全内反射来引导宽范围的光的波长，包括激发和感测波长的光，通过分析物。这是可能的，因为即使二氧化硅的折射率高于水，光子晶体波导的包层区域可以布置成具有比水低的有效折射率。可以根据本发明的其它实施方案来测试具有比水更低的折射率的许多其它分析物。
