摘要
多芯光子晶体光纤(MCPCF)是实现高功率超连续谱输出的一个重要研究方向，而如何解决多芯光子晶体光纤的低损耗熔接问题是实现全光纤化的关键。介绍了一种通过选择性空气孔塌缩技术实现七芯光子晶体光纤低损耗熔接的方法。数值模拟了处理前后七芯光子晶体光纤的模场特性以及对熔接损耗的影响。实验上对七芯光子晶体光纤进行了选择性空气孔塌缩处理，实现了和纤芯直径为15 μm的双包层光纤的低损耗熔接，损耗值为0.22 dB。
Abstract
The muti-core photonic crystal fibers (MCPCF) is one major research direction to realize high power supercontinuum, and a key problem to realize all-fiber is how to solve the low loss fusion splicing for MCPCF. One method to realize low loss fusion splicing for seven-core PCF by selected air hole collapse technique is introduced. Mode field property and its effect on splicing loss both before and after process are numerically simulated. Selected air hole collapse is achieved for a seven-core PCF experimentally and a low loss (0.22 dB) is realized for splicing to a double cladding fiber with core diameter of 15 μm.
