Double-core D-type photonic crystal fiber refractive index sensor based on grid coating

A D-type fiber optic refractive index sensor based on surface plasmon resonance (SPR) principle is proposed in this paper. The sensor is composed of a double core structure and a grid-coated photonic crystal fiber (PCF) on the polishing surface. The resonant wavelength can be adjusted and the refractive index sensitivity can be improved by introducing a gold grating film. Under the anisotropic perfect matching layer boundary condition, the simulation was preformed through the full-vector finite element method (FEM). The results show that the refractive index measurement range of the sensor is 1.30~1.33, the sensitivity can reach 12000 nm• RIU-1, and the resolution can reach 1.01×10-5 RIU.
