基于全矢量有限元法研究了金属纳米薄膜对大孔径光子晶体光纤(PCF)传感特性的影响.针对所设计的大孔径PCF传感模型,数值模拟了PCF材料中金属纳米薄膜厚度不同以及不均匀时所表现的吸收特性:当金属纳米薄膜的厚度为均匀的30 nm和40nm时,分别在0.535 μm和0.565 μm处出现非常明显的吸收峰,且HEX11和HEy11两个模式完美简并;当有一个空气孔中的金属纳米薄膜厚度为30 nm,其他空气孔中的金属纳米薄膜厚度为40nm时,HEx11和HEy11模式的损耗曲线明显不简并,能够表现出两种金属纳米薄膜厚度的吸收特性;模拟计算了所设计传感器不同测量方法所表达的灵敏度与分辨率.研究结果为PCF传感器中金属纳米镀膜的实际操作和使用提供了理论依据.
