提出了一种新型的用于流体静压传感的双芯双孔光纤（DCDHF）。在DCDHF的横截面中采用两个纤维芯和两个空气孔。DCDHF的两个光纤芯之间的模式耦合对压力引起的折射率变化敏感，这确保了对施加到DCDHF的压力的检测。采用两个大的空气孔来增强DCDHF的压力引起的折射率变化，这基本上提供了一个内置的换能机构来增强基于DCDHF的压力传感器的灵敏度。将一段DCDHF光纤与两段单模光纤简单拼接而成的DCDHF压力传感器，详细介绍了其工作原理。模拟结果表明，当偏振光入射到DCDHF的另一个纤芯中时，在固定长度的DCDHF的一个纤芯处，输出光谱的波长偏移与DCDHF所利用的压力之间存在线性关系。本文还研究了不同结构参数的DCDHF的压力传感特性。
We propose a novel dual-core dual-hole fiber (DCDHF) for hydrostatic pressure sensing. Two fiber cores and two air holes are employed in the cross-section of the DCDHF. The mode coupling between two fiber cores of the DCDHF is sensitive to the pressure-induced index change which ensures the detection of the pressure applied to the DCDHF. Two large air holes are employed to enhance the pressure-induced index change for the DCDHF which essentially provides a built-in transducing mechanism to enhance the sensitivity for the DCDHF-based pressure sensor. The DCDHF-based pressure sensor is simply formed by splicing a segment of DCDHF to two segments of single mode fibers and its operation principle is introduced in details. Simulations show that there is a linear relationship between the pressure untilized on the DCDHF and the wavelength shift of the output spectrum at one fiber core of the DCDHF with a fixed length when the polarized light is injected into another fiber core of the DCDHF. DCDHFs with different structure parameters for pressure sensing are also investigated.
