摘　　要： 光子晶体光纤与普通单模光纤的低损耗熔接是影响光子晶体光纤实用化的重要技术。针对自行设计的光子晶体光纤,对其与普通单模光纤的熔接损耗机制进行了理论和实验研究。首先分析了影响熔接损耗的主要因素,然后理论计算了光子晶体光纤与普通单模光纤之间的耦合损耗,最后采用常规电弧放电熔接技术对光子晶体光纤与单模光纤的熔接损耗进行了实验研究,通过优化放电参数,使熔接损耗可以降到0.7dB以下,满足了实际应用的要求。该方法为其他类型的光子晶体光纤与普通单模光纤的熔接提供了借鉴。 The low-loss splice between photonic crystal fibers （PCFs） and normal single-mode fibers is an important technique that influences the application of PCFs. Based on the self-designed PCF, the splice loss mechanism between PCFs and single-mode fibers was studied theoretically and experimentally. The main factors that affect the splice toss was analyzed, and the splice loss between the two types of fibers was calculated. Using traditional arc-fusion method, the experiment study on splice loss between the PCFs and single-mode fibers was performed. The splice loss can drop to below 0.7 dB by optimizing the discharge parameters, and then satisfy the application request. This method can provide the reference for other similar splicing between PCFs and single-mode fibers.
