报道了一种基于表面等离子体共振（SPR）现象的平面波导传感器系统的研制及其特性。所设计的平面波导由Cr-、Au-薄膜和熔融石英衬底组成。首先，我们研究了所提出的SPR波导的传感性能，使用解析模拟。并且，我们测量了四种不同蔗糖溶液的SPR曲线，其具有从1.333到1.34的可变折射率，对应于从0到50，000 ppm的浓度。最后，将实验结果与仿真结果进行比较，表明SPR平面传感器系统可以应用于食品、医药、化工等行业的加工过程。(C)2009爱思唯尔有限公司版权所有。
We report on the development and characteristics of a planar waveguide sensor system based on surface plasmon resonance (SPR) phenomenon. The designed planar waveguide consists of Cr-, Au- thin films and fused silica substrate. Firstly, we investigate the sensing performance of the proposed SPR waveguide using analytical simulation. And, we measure SPR curves of four different sucrose solutions, having variable refractive index from 1.333 to 1.34 corresponding from 0 to 50,000 ppm in concentration. Finally, comparing the experimental result to the simulation result, we present the SPR planar sensor system can be applied to fabrication process of food, medicine and chemical industries.
