提出了一种基于高双折射光子晶体光纤（PCF）的新型静压压力传感器，该传感器具有高灵敏度和沿着光纤长度的宽检测范围。通过在包层区引入两个长轴受压的椭圆中空通道，该光子晶体光纤呈现出类似于10（-2）的高阶双折射。这两个椭圆形的空气孔的后果进行了研究，以提高压力灵敏度。本文承诺在1cm长的光纤中，在椭圆包层短轴为0.468 μ m、螺距常数为1.5 μ m的情况下，通过其透射光谱产生87.5 μ m/MPa的非常大的压力灵敏度。
This paper presents a novel hydrostatic pressure sensor using high birefringence photonic crystal fibers (PCFs), featuring an enhanced sensitivity with wide range of detection along the length of fiber. The proposed PCFs exhibit higher order of birefringence as similar to 10(-2), which is achieved by the introduction of two elliptical hollow channels stressed at major axis in the cladding region. The consequence of these two elliptical air holes is investigated to enhance the pressure sensitivity. This paper promises to yield very large pressure sensitivity of 87.5 pm/MPa through its transmission spectrum at a pitch constant of 1.5 mu m with 0.468 mu m of minor axis of elliptical cladding in a fiber length of 1 cm.
