Abstract

A photonic crystal fiber-based localized surface Plasmon resonance sensor with supermodes is analyzed. In the boundary condition of anisotropic perfectly matched layer (PML), a full-vector finite element method (FEM)is used to calculate the fiber model. Numerical results indicate that the excitation of the plasmon mode is sensitive to the change of the refractive index of adjacent analyte. The maximum amplitude sensitivity of the fiber sensor is 1124dB/RIU. Its resolution can reach 4×10^-5RIU. The maximum spectral sensitivity of the sensor can be about 2000nm/RIU. Its resolution can reach 5×10^-6 RIU.
