In this study, the dual-channel photonic crystal fibre (PCF) based surface plasmon resonance (SPR) sensor has been proposed to sense multi-analyte. Gold and silver used as plasmonic layers. Full vectorial Finite Element Method (FV-FEM) have been used to perform numerical analysis. Also, the spectral interrogation method has been used to calculate the sensitivity of the proposed sensor structure. According to numerical results, the highest sensitivity levels are obtained as 6800 nm/RIU with 1.47x10−5 RIU, where the average sensitivities are calculated as 3500 nm/RIU and 3100 nm/RIU for fixed and variable refractive indices, respectively.

Keywords: Photonic crystal fiber (PCF), Surface plasmon resonance (SPR), Multi analyte. Multi-channel, Fiber optic sensor.
