摘要: 提出了利用光子晶体光纤空气孔塌缩技术制作光子晶体光纤表面等离子体共振传感器,构建了空气孔完全塌缩的光子晶体光纤表面等离子体共振传感器模型，并模拟计算了其中的表面等离子体共振效应。制作了全光纤化的波长检测型的光子晶体光纤表面等离子体共振传感器,利用超连续谱光源进行了相关实验。实验结果表明:以空气为待测环境介质时，对应的共振波长为465 nm，与理论计算相符合。

Abstract: A method of using the air-hole collapsed technology of photonic crystal fiber(PCF) to make surface plasmon resonance (SPR) sensors has been proposed. The air-hole completely collapsed PCF-SPR sensor model has been established and simulated. All-fibered wavelength-detection PCF-SPR sensors were constructed, and a supercontinuum source was used to do the correlated experiments. When air is the ambient medium to be tested, the measured resonance wavelength is 465 nm, which accords with the simulation. -
