提出了一种基于双核光子晶体光纤（DC-PCF）的新型静液压力传感器。两个实心光纤芯被横截面上的一个空气孔隔开，在DC-PCF内部形成两个独立的波导，并伴有模式耦合。数值研究了不同静水压力下直流- pcf两芯实心光纤的模态耦合。提出了一种压力传感系统，并对其性能进行了数值研究。计算表明，基于10cm DC-PCF的静液压力传感器的传感范围为0 ~ 1000mpa，灵敏度为3.47 pm/MPa。
We propose a novel hydrostatic pressure sensor based on a dual-core photonic crystal fiber (DC-PCF). Two solid fiber cores separated by an air hole in the cross-section lead to two independent waveguides inside the DC-PCF which accompany with mode coupling. The mode coupling of two solid fiber cores of the DC-PCF under different hydrostatic pressure is numerically investigated. A pressure sensing system is proposed and performances of the pressure sensor have been numerically investigated. Our calculations show a hydrostatic pressure sensor based on a 10-cm DC-PCF has a sensing range from 0 to 1000 MPa and a sensitivity of 3.47 pm/MPa.
