【摘要】 光纤电场传感器具有很大的应用潜力，但是其温度稳定性难以解决。论文针对光纤电场传感器存在温度稳定难以解决的技术瓶颈，提出一种通过调节传感器结构参数便可以消除温度敏感性的三光束干涉(TBI)电场传感器。论文从微纳光纤之间的耦合方程出发，详细论述了温度对TBI电场传感器的影响机制，讨论了TBI电场传感器的结构参数对传感器温度稳定性的影响规律，给出了具有良好温度稳定性的传感器最优结构设计方法。理论上，该电场传感器的温度稳定性可降低至在0 pm/℃。温度实验测试结果表明，通过微调工艺可以将传感器的温度稳定性控制在2.6 pm/℃左右。论文研究工作对提升全光纤电场传感器的技术水平，推广其在工程中的实际应用具有重要意义。更多还原

【Abstract】 Optical fiber E-field sensor has many potential applications, but it is difficult to solve the temperature stability. So, we report a three-beam interference(TBI)E-field sensor that can eliminate the temperature sensitivity by adjusting the parameters of sensor. In accordance with the coupling equation between micro-nano fibers, we discuss the mechanism for influence of temperature on the TBI E-field sensor, and the influence of the sensor’s parameters for temperature stability is analyzed. Finally, we give an optimal design method for low-sensitivity to temperature. Theoretically, temperature stability of the E-field sensor can be reduced to 0 pm/℃. Experiment show that the temperature stability of the sensor can be controlled at about 2.6 pm/℃ through the fine-tuning process. This work is of great significance to improve the technical level of all-fiber electric field sensor and popularize its practical application in engineering.更多还原
