Abstract
In recent years, the D-shaped photonic-crystal-fiber localized surface-plasmon-resonance (LSPR) sensor is a research hot spot, especially for liquid refractive-index sensors. In this paper, we propose a doublemeasurement-accuracy LSPR sensor. In numerical simulations, when the refractive index of the analyte changes from 1.33 to 1.4, we obtain the maximum sensitivity equal to 15,500 nm/RIU. At refractive index values of the analyte equal to 1.38 and 1.39, there are two resonance peaks, and the wavelength sensitivity of the second peak is 25,000 nm/RIU, which has a good prospect in specific liquid detection.
