We report an investigation of conditions for the initiation of fiber fuse (IFF), a kind of catastrophic damage that troubles all kinds of optical fibers, in silica-based optical fibers. The fibers of different chemical compositions were processed and tested in controlled conditions without mechanical damages before the IFF. For all the fibers of IFF, the same correlation between the critical temperatures and the optical powers transmitted therein was revealed for the first time. The fibers of different chemical compositions exhibited different resistances to the IFF under the threshold powers for propagation of fiber fuses. The results offered promise for predicting fiber fuses in optical fiber systems, which could facilitate avoiding catastrophic losses. They could direct the optimization of fiber production technologies for suppressing the damages, as well as open a new path towards controlled utilization of fiber fuse in in-fiber microstructure fabrication.
我们报告了一项关于引发光纤熔丝（IFF）条件的研究，IFF是困扰各类石英基光纤的一种灾难性损伤。在引发IFF之前，对不同化学成分的光纤进行了加工，并在无机械损伤的受控条件下进行了测试。对于所有出现IFF的光纤，首次揭示了临界温度与其中传输的光功率之间存在相同的相关性。在低于光纤熔丝传播阈值功率的情况下，不同化学成分的光纤对IFF表现出不同的抗性。这些结果为预测光纤系统中的光纤熔丝带来了希望，这有助于避免灾难性损失。它们可以指导优化光纤生产技术以抑制损伤，同时为在光纤微结构制造中可控利用光纤熔丝开辟一条新途径。
