实验研究了椭圆芯、D形、蝴蝶结型高双折射光纤的静压、温度和应变灵敏度。研究了偏振和偏振敏感LP（01）-LP（11）模式间干涉响应。灵敏度用描述余弦响应中的2 pi相移的实验参数T（x，j）表示。结果发现，蝴蝶结光纤表现出线性响应的所有研究的外部扰动，除了偏振响应的基模温度，而椭圆芯和D形光纤的特点是由一个非线性的敏感性，温度和静水压力。讨论了各种光纤在光纤传感器中的应用。
The sensitivity to hydrostatic pressure, temperature, and strain of elliptical-core, D-shaped, bow-tie highly birefringent fibers is experimentally investigated. Both polarimetric and polarization sensitive LP(01)-LP(11) intermodal interferometric responses are studied. The sensitivities are expressed in terms of the experimental parameters T(x,j) describing a 2pi phase shift in the cosine response. It is found that bow-tie fibers exhibit a linear response to all the studied external perturbations except for the polarimetric response of the fundamental mode to temperature, while elliptical-core and D-shaped fibers are characterized by a nonlinear sensitivity to both temperature and hydrostatic pressure. The application to fiber-optic sensors of each type of fiber is discussed.
