摘要
The dynamic characteristics of high sensitivity temperature sensor are studied by using siphon method to fill the air hole near the core of the hollow photonic crystal fiber with Cargille matching liquid,and the two ends are fused with single-mode fiber in this work.We analyzed the working principle of filled photonic crystal fiber sensor by using the standard coupling mode theory of directional coupler.The coupling process was simulated by COMSOL software.When the photonic crystal fiber filled with 10 mm liquid was scanned by tunable laser,the temperature sensitivity was 7.50 nm /℃,the average temperature response time was 0.317 s,the average release time was 3.732 s,and the temperature variation linearity was 100%.The experimental results show that the liquid filled photonic crystal fiber has the advantages of high temperature sensitivity,fast response time and good linearity.
