摘要：
A dual-channel photonic crystal fiber sensor based on the surface plasmon resonance effect is proposed and numerically investigated. The proposed design consists of two concentric channels, with an external coating of gold (Au) on solid silica. Multiple analytes are analyzed based on two different modes operating in the first and second channel, and wavelength sensitivity of 1000 nm/RIU and 3750 nm/RIU respectively. The proposed sensor design could be used in various sensing applications, e.g., for chemicals, biochemicals, organics, and other lower-index liquids having refractive index in the range of 1.30-1.40.
