摘要：

A novel surface plasmon-polariton (SPP) refractive index sensor based on the coupling of a split waveguide mode with a cavity mode in the metal is proposed and studied in this paper. Both analytic and simulated results show that the resonant wavelength of the sensor has a linear relationship with the refractive index of materials under sensing. Based on the relationship, the refractive index of the material can be obtained from the detection of the resonant wavelength. The resolution of refractive index of the nanometeric sensor can reach as high as 10(-6), given the wavelength resolution of 0.01 nm. It can be applied to high-resolution biosensor.
