摘要

A dual-channel sensor was proposed by further processing a gap on the D-shaped surface of a photonic crystal fiber (PCF). The simultaneous and independent measurement for refractive index (RI) and temperature was theoretically demonstrated. On the dual-channel surfaces, the Ag films were elaborated to improve the sensing performance for RI based on surface plasmon resonance (SPR) effect. The sensing performance of the temperature channel was improved by further-overlaying the polydimethylsiloxane (PDMS) film. Furthermore, the TiO2 film was introduced to protect the silver away from oxidation and optimized the sensing performance. When the thickness of Ag film is 45 nm and the thickness of TiO2 film is 13 nm, the highest sensitivities of RI and temperature were respectively obtained as 6700 nm/RIU and - 21 nm/degrees C.
