摘要
表面等离子体共振技术的应用日益广泛,但是由于其敏感单元制备复杂,尤其是光纤表面等离子体共振传感系统的传输效率较低,使得此类传感实验很难在本科教学中进行开展。本文提出了一种多模-单模结构光纤 SPR 传感实验,简化了敏感单元的结构,提高了传输效率。通过对水、丙酮、乙醇、异丙醇和正硅酸乙酯进行了实验测量,结果表明,该实验装置的平均灵敏度可以达到2902 nm/RIU,敏感单元制作简单,制作成功率高,非常适合于本科教学中采用。

Abstract:
Surface plasma resonance technology is increasingly widely used,but due to the complex preparation of sensitive units,especially the low transmission efficiency of optical fiber surface plasma resonance sensor system,such sensor experiments are difficult to carry out in undergraduate teaching.It presents a multimode- inglemode structure fiber SPR sensor experiment which simplifies the structure of sensitive units and improves the transmission efficiency.Through experimental measurements of water,acetone,ethanol,isopropyl alcohol and ethyl orthosilicate,the results show that the average sensitivity of the experimental device can reach the 2902 nm/RIU,sensitive unit,which is simple to make and has a high success rate,which is very suitable for use in undergraduate teaching.
