综述了近年来基于光纤端面集成金属光子结构传感器的发展状况。按照等离激元共振方式和传感器探测原理的不同, 将其分为基于表面等离激元共振(SPR)的光纤传感器、基于局域化表面等离激元共振(LSPR)的光纤传感器、基于杂化型等离激元的光纤传感器以及基于表面增强拉曼散射(SERS)效应的光纤传感器。对各类传感器的制备方法、光物理学原理及探测性能进行了概括、对比和总结。

The recent development status of the sensors based on metallic photonic structures integrated onto end facets of fibers is reviewed. On the basis of the differences in schemes of plasmon resonances and detection principles of sensors, the above sensors are usually categorized into fiber sensors based on surface plasmon resonance (SPR), fiber sensors based on localized surface plasmon resonance (LSPR), fiber sensors based on hybrid plasmons, and fiber sensors based on surface-enhanced Raman scattering (SERS) effect. In addition, the fabrication techniques, photophysical principles, and detection performances of these kinds of sensors are summarized, compared, and concluded.
