我们使用数值模拟来研究如何弯曲的光纤芯边界的影响的衰减空心反共振光纤。我们展示了“负”曲率纤芯边界在减少限制损耗方面的重要性，以及对于某些曲率，光功率如何共振地耦合到包层模式。我们模拟弯曲损耗，并发现与以前报道的实验结果一致。
We use numerical simulations to investigate how the curvature of the fiber core boundary influences the attenuation of hollow antiresonant fibers. We show the importance of a "negative" curvature core boundary in reducing confinement losses and also how, for certain curvatures, optical power is coupled resonantly to cladding modes. We simulate bending losses and find results in agreement with previously-reported experiments.
