本文用有限元法研究了边孔光纤的压力双折射与其几何形状的关系。我们证明了这种光纤的压力灵敏度与/spl phi//sup 2/呈线性关系，其中/spl phi/是侧孔中心与芯中心轴之间的角度，芯中心与侧孔切线之间的角度。两个不同的侧孔光纤传感器获得的实验数据显示同意非常好（在10%以内）与理论预测。
The dependency of the pressure-induced birefringence of a side-hole fiber on its geometry has been numerically investigated using the finite element method. We demonstrate that the pressure sensitivity of such a fiber shows a linear dependence on /spl phi//sup 2/, where /spl phi/ is the angle between the side hole center and core center axis and the core center to side-hole tangent. Experimental data obtained with two different side-hole fiber sensors are shown to agree extremely well (to within 10%) with theoretical predictions.
