提出并实现了一种基于飞秒激光脉冲在偏置多模光纤（MMF）干涉仪中写入光纤布拉格光栅（FBG）的应变和温度同时测量的混合传感结构。在两个单模光纤（SMF）之间拼接一段磁动势（MMF）形成马赫-曾德尔干涉仪，获得了高达15 dB的高干涉条纹。传感实验结果表明，应变灵敏度为-1.17 pm/με和0.6498 pm/με的MZI和布拉格峰的倾角，而温度灵敏度为42.84 pm/°C和19.96 pm/°C的测量。矩阵分析表明，该传感器的应变和温度分辨率分别高达±12.36 με和±0.35 °C。此外，该传感器具有制作简单、光谱质量好、分辨率高等优点，在双参数传感方面具有潜在的应用前景。
A hybrid sensing configuration for simultaneous measurement of strain and temperature based on fiber Bragg grating (FBG) written in an offset multimode fiber (MMF) interferometer using femtosecond laser pulse is proposed and demonstrated. A Mach–Zehnder interferometer is formed by splicing a section of MMF between two single-mode fibers (SMFs) and a high interference fringe of up to 15 dB is achieved. The sensing experimental results show a strain sensitivity of −1.17 pm/με and 0.6498 pm/με for the dip of MZI and Bragg peak, while a temperature sensitivity of 42.84 pm/°C and 19.96 pm/°C is measured. Furthermore, the matrix analysis has found that the strain and temperature resolution of the sensor are as high as ±12.36 με and ±0.35 °C, respectively. In addition, the sensor has merits of simple fabrication, good spectral quality, and high resolution, which shows attractive potential applications in dual-parameter sensing.
