摘要
提出了一种新型光纤光栅中心波长与带宽独立调谐方法。将光纤光栅沿圆柱形弹性梁的轴向成一定角度粘贴于侧面,通过改变梁的扭转角与侧向位移,实现了光纤布拉格光栅中心波长与带宽的准线性独立调谐。实验上获得了8.28 nm准无啁啾波长调谐和5.32 nm准无中心波长漂移的带宽调谐,实验结果与理论分析一致。
Abstract
A new independent tuning method of the center wavelength and the bandwidth of fiber grating is demonstrated. The fiber grating is bonded to the side surface of elastic beam with a determinate angle along its axis direction. The center wavelength and the bandwidth of the fiber grating can be quasi-linearly tuned respectively through changing the torsional angle and the lateral displacement. In the experiments, it is demonstrated the quasi-chirp-free wavelength tuning of 8.28 nm and the bandwidth tuning of 5.32 nm in which the center wavelength is quasi-shift-free. The experimental results are in good agreement with the theoretical analyses.
