We examined the fiber-fuse propagation characteristics in hole-assisted fibers (HAFs) when the diameter of an inscribed circle linking the air holes was almost the same as the diameter of the melted area caused by the fiber fuse. We observed a new propagation mode for the fiber fuse in HAF with a damage track whose period was approximately 30 times longer than that in conventional single-mode fiber. We also made the first observation of a new threshold power (upper threshold) for the fiber fuse.
我们研究了光纤熔接在光纤中传播的特性，此时连接空气孔的内切圆直径与光纤熔接产生的熔融区域直径几乎相同。我们观察到在带有损伤轨迹的孔辅助光纤中，光纤熔接出现了一种新的传播模式，其周期大约是传统单模光纤的 30 倍。我们还首次观察到了光纤熔接的一个新的阈值功率（上阈值）。
