在这篇综述论文中，我们提出了硅基光纤的辐射效应。我们首先描述了在辐照下引起微观和宏观变化的机制：辐射诱导衰减，辐射诱导发射和压实。然后，我们讨论了与光纤相关的各种参数的影响，恶劣的环境和基于光纤的应用程序的振幅和动力学的这些变化。然后，我们重点介绍了过去几年取得的进展。我们总结的主要结果，光纤的脆弱性和硬化与几个设施，如兆焦耳级激光器，ITER，大型强子对撞机，核电站或空间应用的辐射约束。根据在这些项目中获得的经验，我们提出了在不久的将来必须克服的一些挑战，以允许在辐射环境中更深入地集成光纤和基于光纤的传感器。
In this review paper, we present radiation effects on silica-based optical fibers. We first describe the mechanisms inducing microscopic and macroscopic changes under irradiation: radiation-induced attenuation, radiation-induced emission and compaction. We then discuss the influence of various parameters related to the optical fiber, to the harsh environments and to the fiber-based applications on the amplitudes and kinetics of these changes. Then, we focus on advances obtained over the last years. We summarize the main results regarding the fiber vulnerability and hardening to radiative constraints associated with several facilities such as Megajoule class lasers, ITER, LHC, nuclear power plants or with space applications. Based on the experience gained during these projects, we suggest some of the challenges that will have to be overcome in the near future to allow a deeper integration of fibers and fiber-based sensors in radiative environments.
