空芯光子晶体光纤具有很高的气体传感应用潜力，因为可以有效地获得大的光-气体相互作用长度。然而，为了增强气体到光纤空芯中的有效扩散，需要多耦合间隙，这引起了在开发实际系统之前必须评估的耦合损耗问题。本文研究了单模光纤和两种不同类型的空芯光子晶体光纤的耦合损耗与横向和轴向间隙失调的关系。此外，这些光纤的拼接实验结果也。
Hollow-core photonic crystal fibres have a high potential for gas sensing applications, since large light-gas interaction lengths can be effectively attained. Nevertheless, in order to enhance effective diffusion of gas into the fibre hollow-core, multi-coupling gaps are needed, which raise coupling loss issues that must be evaluated prior to the development of practical systems. In this communication we present a study on the coupling losses dependence on lateral and axial gap misalignment for single-mode fibre and two different types of hollow-core photonic crystal fibres. In addition, experimental results on the splicing of these fibres are also presented.
