Abstract

In this work, single mode fibers with coatings doped with SiO₂ and Al₂O₃ were developed and their radiation induced attenuation (RIA) spectra at 1310 nm were analyzed. These results were compared to undoped fibers and two commercially used single mode fibers, G652, PM1016-C during and after γ-irradiation at different temperatures. Results show that the fibers doped with SiO₂ and Al₂O₃ exhibited significant lower attenuation than other fibers. At a temperature of −45 °C and a gamma irradiation dose of 2 kGy, the doped fibers showed an RIA of only 0.73 dB/Km, while the other fibers experienced losses exceeding 8 dB/km. Even when the irradiation dose was increased to 200 kGy, the prepared fiber exhibited a maximum attenuation of just 4.37 dB/km, which is still lower than the others. Furthermore, the doped fibers demonstrated rapid recovery of attenuation levels after the irradiation was removed. The resulted indicate that the incorporation of Al₂O₃ and SiO₂ significantly enhances radiation resistance. This study provides valuable insights for designing high-performance, radiation-resistant fibers suitable for use in harsh environments, such as deep space, where radiation exposure is intense.

Al2O3和SiO2掺杂对提高不同温度下光纤抗γ辐射性能的影响

本文制备了掺杂SiO2和Al2O3涂层的单模光纤，并对其1310 nm处的辐射诱导衰减（RIA）光谱进行了分析。这些结果与未掺杂光纤和两种商用单模光纤G652、PM1016-C在不同温度下辐照和辐照后的结果进行了比较。结果表明，掺SiO2和Al2O3的光纤衰减明显低于其他光纤。在−45℃和2 kGy的γ辐照剂量下，掺杂光纤的辐射损耗仅为0.73 dB/Km，而其他光纤的辐射损耗超过8 dB/Km。当辐照剂量增加到200 kGy时，所制备的光纤的最大衰减仅为4.37 dB/km，仍低于其他光纤。此外，在去除辐照后，掺杂纤维表现出衰减水平的快速恢复。结果表明，Al2O3和SiO2的掺入显著提高了材料的抗辐射能力。这项研究为设计高性能、抗辐射纤维提供了有价值的见解，这些纤维适合在恶劣环境中使用，例如深空，那里的辐射暴露强烈。

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
