摘　　要：当代的航空航天与核能技术飞速发展,迫切需要具有抗辐照性能的光纤。特种光纤在空间通信与传感、太空测量与采集、卫星地面共联等领域已扮演重要角色。然而,这些极端环境下的辐射可能造成光纤损伤,降低其传输能力,影响使用的稳定性和安全性。回顾了过去关于提升光纤抗辐照性能的研究,并介绍了当前提高传输光纤抗辐照性能的研究现状,现有方法包括改变纤芯或包层组分以及预处理等,通过对比各种方法对光纤的作用机理和影响程度,发现结合多种方法应用于传输光纤能够显著提升其抗辐照性能,尤其是结合预辐照、载H2、载D2、退火、光漂白以及适当掺杂元素,能够显著提升光纤的抗辐照性能。这些发现为光纤在极端环境中的可靠应用提供了有效途径,其成功应用为未来的光纤研究和应用开辟了新的方向,未来的研究可以进一步探索更加创新和高效的方法,以不断提升光纤在极端条件下的可靠性和稳定性。With the rapid development of aerospace and nuclear energy technologies,there is an urgent need for optical fibers with excellent anti-radiation properties.Specialized optical fibers are crucial for applications in space communication and sensing,space measurement and acquisition,and satellite-to-ground communication However,radiation in extreme environments can damage fibers,reduce their transmission capacity,and compromise their stability and safety.This paper reviews the relevant literature on improving the anti-radiation performance of optical fibers and presents the current status of efforts to improve the anti-radiation performance of these fibers.Existing methods include altering the core or cladding materials and implementing various pre-treatments.By comparing the mechanisms and influence of these approaches,it is evident that combining multiple methods can remarkably improve the anti-radiation performance of transmission optical fibers.Specifically,combining pre-irradiation,H2 and D2 loading,annealing,photobleaching,and appropriate doping elements substantially improves the fiber anti-radiation performance.These findings offer a reliable approach for deploying optical fibers in extreme environments,and their successful implementation paves the way for future optical fiber research and applications,where more innovative and efficient methods can be explored to continually enhance optical fiber reliability and stability under extreme conditions.
