Abstract

In the present work, the effect of gamma radiation on the performance of different types of erbium-doped fibers (EDFs) when they are used in a fiber ring cavity (FRC) configuration is studied. Several pieces of commercial EDF are gamma-ray irradiated with different doses to evaluate the output power variations over time. The influence of different doses, from 150 Gy to 1000 Gy, over the output power level measurement and their amplified spontaneous emission (ASE) are experimentally evaluated both in the C and L bands. By using an FRC configuration we can detect the presence of gamma radiation. We can also estimate the irradiation doses applied to EDFs by measuring the slope of the short-term emission power.

摘要

在本工作中，研究了伽马辐射对不同类型掺铒光纤（EDF）在光纤环形腔（FRC）配置中使用时性能的影响。对几块商用EDF进行不同剂量的伽马射线辐照，以评估输出功率随时间的变化。在C波段和L波段通过实验评估了从150 Gy到1000 Gy的不同剂量对输出功率水平测量及其放大自发辐射（ASE）的影响。通过使用FRC配置，我们可以检测伽马辐射的存在。我们还可以通过测量短期发射功率的斜率来估计施加到EDF上的辐照剂量。
