摘　　要：分析了光纤光栅(FBG)调谐的基本原理,进而采用新颖的调谐结构,设计并实现了一种宽带可调谐的FBG滤波器。该滤波器仅用1支FBG制做而成,其波长调谐范围最高可达40 nm。实验结果表明,该FBG滤波器的调谐波长与调谐步进位移量之间具有良好的二次曲线关系。A novel fiber Bragg grating（FBG） filter was designed and realized based on analyzing basic principle of fiber grating tuning. In the filter,a single FBG is mounted between a fixed clamp and a movable one. The Bragg wavelength of the FBG is tuned by accurately monitoring the displacement of the movable clamp towards the fixed clamp. It is demonstrated that the tunable range of the filter reaches as much as 40 nm. The experimental results indicate that the tuning wavelength has a strictly conic relationship with the displacement of the movable clamp.
