描述了一种基于单模光纤尖端表面等离子体激元的光学激发和询问的传感器。新的询问技术基于对存在激发等离子体时反射的光束的偏振态的分析。初步实验证实了理论分析，并指出了基于新技术的化学传感器的可行性。
A sensor based on the optical excitation and interrogation of a surface plasmon on the tip of a single-mode optical fiber is described. The new interrogation technique is based on the analysis of the state of polarization of the beam reflected in the presence of an excited plasmon. Preliminary experiments confirm the theoretical analysis and point out the feasibility of a chemical sensor based on the new technique.
