摘　　要：提出了一种高折射率液体选择性填充PCF,通过在PCF空气孔填入温敏液体材料,使光纤具有良好的温度传感特性。运用平面波展开法进行仿真研究,优化了PCF结构参数,使其导光性能更佳。同时,设计了三种不同选择性填充方式的PCF进行比较,分析选择性填充方式对带隙特性和温度传感特性的影响,最终选用带隙最宽的PCF进行仿真研究。A high refractive index liquid selective filled PCF is proposed in this paper. By filling temperature sensitive liquid materials in the air holes, the better temperature sensing characteristics can be obtained. The structure parameters is optimized to make the fiber transmission performance well by the plane wave expansion method. Meanwhile, three different selective filled PCFs are designed to compare and analyze the influence of the selective filled methods on the bandgap characteristics and temperature sensing characteristics. And the widest bandgap PCF is selected to simulation study.
