摘要
保偏光纤(PMF)在相干光通信、光纤激光器、光纤传感、光纤陀螺中应用广泛,温度稳定性是其在实际应用中的一个十分关键的问题。理论和实验分析了保偏光纤上写入光栅的特性,特别是全面分析了其温度特性。结果表明,随温度升高,偏振反射峰的间隔缩小。利用保偏光纤光栅的这一特性研究了可以高精度、方便地获得保偏光纤温度特性的新方法。测试了保偏光纤-40~130 ℃的温度特性,实验结果与理论分析的结果一致。
Abstract
Polarization-maintaining fibers (PMF) are widely used in coherent optical communication systems, optical fiber sensors, optical fiber lasers, optical fiber gyros, and so on. The temperature stability is one of the key factors for the application of such fiber. In this paper, the characteristics of the fiber Bragg grating(FBG) fabricated in the PMF are analyzed by both of the theory and experiments. The results show that the higher of the temperature, the narrower of the polarization peak space. This is the theory basis of the high resolution new method to get the temperature characteristic of PMF. The experiments for the PMF at temperature range from -40 ℃ to 130 ℃ are measured, and the results agree well with the theory analysis.
