摘　　要：利用Corning SMF-28(TM)制作了单模纤锥表面等离子体共振传感器,在1384～1614 nm波长范围内,采用波长调制方式对折射率为1.448 0～1.451 0的甘油水溶液进行了检测,分辨率在3×10-5 RIU,这有利于进一步了解单模光纤表面等离子体共振传感器的性能以及在液体折射率检测方面的应用。The design of single-mode tapered optical fiber sensor based on surface plasmon resonance is completed by using Corning SMF-28（TM）.The experiment of detection is studied in the refractive index of glycerol based on wavelength-modulation.The detection range of refractive index of 1.448 0 to 1.451 0 and the resolution of about 3×10-5 are achieved between 1 384 nm and 1 614 nm.The performance of single-mode optical fiber sensor based on surface plasmon resonance and the application of detecting the refractive index of solution are further understood through this work.
