This Letter presents simulation and experimental results of orientation-dependent transverse stress fiber sensors using fiber Bragg gratings (FBGs) inscribed in four-hole suspended-core fibers. Resonant peak shifts and splitting of FBGs were studied as functions of the applied transverse load and fiber orientation. Both simulation and experimental results revealed that the response of FBGs in suspended-core fibers is sensitive to both the orientation and magnitude of an applied transverse stress.
这封信提出了使用光纤布拉格光栅（FBG）在四孔悬芯光纤中刻写的定向横向应力纤维传感器的模拟和实验结果。研究了 FBG 的谐振峰位移和分裂作为施加横向载荷和光纤取向的函数。模拟和实验结果均表明，悬芯光纤中 FBG 的响应对施加的横向应力的方向和大小都很敏感。
