少模光子晶体光纤的模间干涉及传感研究

Research on modular interference and sensing properties of few-mode photonic crystal fiber

以折射率引导的光子晶体光纤模间干涉效应为基础,针对光子晶体光纤中多模干涉效应进行了实验研究,完成了不填充与完全填充时的仿真分析与测试,实验得到了模间干涉图样的漂移情况对比。以完全填充及选择性填充匹配液为研究方式,探讨了其在温度传感领域的应用。

Based on photonic crystal fiber（PCF） inter-modal interference effects of the refractive index guided, this paper studied PCF multimode interference effects, simulations was analyzed and tested with incompletely filled with completely filled, experiments got the contrast drift of the modular interference pattern. The paper discussed the application in the temperature sensing field by completely filled and filled with matching fluid.
