【摘要】 A multi-functional optical fiber sensor based on surface plasmon resonance(SPR) is designed to simultaneously detect temperature(T), magnetic field(H), relative humidity(RH), and voltage(U). In the device, an eight-hole photonic crystal fiber(8-hole PCF) forms the substrate, and gold(Au) films are plated on the alternately distributed air holes, which are subsequently filled with polydimethylsiloxane(PDMS), magnetic fluid(MF), polyvinyl alcohol(PVA), and E7 nematic liquid crystal(E7 NLC) for sensing the four different physical entities. This sensor has a simple structure and significantly improves the integration level and accuracy. Owing to these merits, the design has large application potential.更多还原
