【 摘 要 】

This paper presents the fabrication and simulation of tapered optical fiber. To characterize the properties of these tapered optical fiber sensors, sugar solutions ranging from 0 to 20 in weight percent were utilized. The measured reflection spectra obtained from this SPR sensor shows the observation of a dip originated from the light absorption by the generated surface plasmon wave. The dip reflectance shifts with the increase in the refractive index. A simulation of the experiment was made using OptiFDTD. The simulation and the experiment showed a similar result. The result suggests that a compact sensor based on this structure may be useful for refractive index sensors.
