倾斜光纤光栅是一类特殊的布拉格光纤光栅，在光学滤波、光纤传感、光纤通信等方面具有重要的应用价值。简要介绍了倾斜光纤光栅中的模式耦合机理，全面回顾了其理论研究、制作技术以及应用研究的发展历史与现状。基于其滤波特性，指出倾斜光纤光栅是抑制大功率光纤激光系统中受激拉曼散射的一种非常有潜力的技术途径。

As a special kind of fiber Bragg gratings, tilted fiber Bragg gratings (TFBG) have some good features, which are of great application value in optical filtering, fiber sensors, optical fiber communication, etc. In this paper, the mode coupling mechanism of TFBG is briefly introduced. Then a general review on the theories, fabrications and applications of TFBG is presented. The TFBG is a potential technique to suppress stimulated Raman scattering in high power fiber laser systems based on its filtering characteristics.
