利用均质、等厚及等腰梯形的悬臂梁，对刚性粘贴其表面的光纤光栅的布喇格反射中心波长在1557．68～1564．2nm范围内进行了线性调谐，同时带宽为外0.52nm的均匀周期的光纤光栅被调谐成带宽为2．52nm的啁啾光栅，且啁啾量可调。随着带宽的增加，反射谱的峰值功率呈减弱的趋势。
The Bragg reflection central wavelength of the fiber grating rigidly pasted on the surface is linearly tuned in the range of 1557.68 ~ 1564.2nm with the bandwidth of 0.52nm The uniform periodic fiber grating is tuned to a chirped grating with a bandwidth of 2.52 nm, and the amount of chirp is adjustable. As the bandwidth increases, the peak power of the reflection spectrum tends to weaken.
