| 中文摘要: |
| 倾斜光纤光栅作为一种特殊结构的光纤光栅，近年来受到了研究人员的广泛关注。基于模式耦合理论，仿真研究了光栅周期对倾斜光纤光栅透射谱的影响规律。研究结果表明，纤芯导模与包层模的波长差和光栅周期之间存在良好的线性关系。利用这一结论可提高倾斜光纤光栅在应变测量中的灵敏度和检测精度，且能够实现单光纤多测量的目的。 |

| In recent years, tilted fiber Bragg gratings have attracted much attention as a kind of particular structure fiber Bragg gratings. Based on mode coupling theory, the effect of grating period on transmission spectrum of tilted fiber Bragg grating (TFBG) were investigated by means of simulation method. The results show that the shift of wavelength displays a good linear relationship with period. The conclusion is very useful in improving the sensitivity and measurement accuracy in strain measurement. In addition, a single fiber could be used to measure multiple sets of data. |
