摘　　要：本文提出了一种引入渐变折射率多模光纤作为过渡光纤的嵌套空芯反谐振光纤与单模光纤的低损耗熔接方法。使用渐变折射率多模光纤作为模场适配光纤,利用其自成像效应扩大单模光纤中的模场,实现了嵌套空芯反谐振光纤与单模光纤的模场匹配。实验中探究了熔接时放电时间和放电功率对熔接损耗的影响。基于优化后的熔接方案,有效保护了嵌套空芯反谐振光纤熔接端面微结构的完整性,平均熔接损耗低至0.60 dB。实验结果对提高嵌套空芯反谐振光纤与现有光纤体系的兼容性提供了参考。This paper presents a low-loss fusion splice method between the nested hollow-core anti-resonant fiber(HC-ARF)and single-mode fiber(SMF)by introducing a graded-index multi-mode fiber(GIMF)as a transition fiber.The mode field matching between the nested HC-ARF and the SMF is achieved by using the GIMF as the mode field adapting fiber and expanding the mode field in the SMF by using its self-imaging effect.The effects of discharge time and discharge power on fusion splice loss during fusion splicing are explored in the experiments.Based on an optimized fusion splicing scheme,the integrity of the microstructure of the nested HC-ARF fusion splicing end face is effectively protected,and the average fusion splicing loss is as low as 0.60 dB.The experimental results provide a reference to improve the compatibility of the nested hollow-core anti-resonant fibers with the existing fiber system.
