Abstract

We investigate a simple structure in which a polarization-maintaining fiber (PMF) is sandwiched between two single-mode fibers (SMFs). By injecting broadband light and observing the modal interference spectrum of the transmitted light in the 870 nm range, we identify a clear shift dependent on the strain applied to the PMF. In addition, we demonstrate that in the same wavelength range, the strain applied to the SMFs before and after the PMF does not influence the interference spectrum. This result confirms that only the PMF segment exhibits strain sensitivity.

基于偏振保持光纤模态干涉频谱的应变传感

我们研究了一种简单的结构，其中在两根单模光纤（SMF）之间夹着一根偏振保持光纤（PMF）。通过注入宽带光并观察 870 nm 波长范围内透射光的模态干涉光谱，我们发现了与施加在 PMF 上的应变有关的明显偏移。此外，我们还证明，在相同的波长范围内，在 PMF 前后对 SMF 施加的应变不会影响干涉频谱。这一结果证实，只有 PMF 段表现出应变敏感性。
