摘要

We demonstrate a fiber refractive index (RI) sensor based on excessively tilted fiber grating (ExTFG) immobilized by large-size plasmonic gold nanosells(GNSs). The GNSs are covalently linked on ExTFG surface. Experimental results demonstrate that both the intensity of transverse magnetic (TM) and transverse electric (TE) mode of ExTFG are significantly modulated by the localized surface Plasmon resonance (LSPR) of GNSs due to the wide-range absorption band. The wavelength RI sensitivities of TM and TE mode in the low RI range of 1.333~1.379 are improved by ~25% and ~14% after GNSs immobilization, respectively, and the intensity RI sensitivities are ~599%/RIU and ~486%/RIU, respectively.
