| 摘 要： | 提出了一种新型的光纤光栅的中心波长与带宽独立调谐的方法。将光纤布拉格光栅(FBG)粘贴于圆环形薄壁截面梁的外表面,通过旋转圆环形薄壁截面梁,即相当于改变光纤光栅的位置来实现中心波长与带宽的独立调谐。实验上得到了6.706 nm准无啁啾的中心波长调谐和5.368 nm的准无中心波长漂移的最大带宽调谐,并且此中心波长和带宽调谐均与拉力呈线性关系,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 proposed.The fiber grating is bonded to the outer surface of loop thin-wall section beam.The center wavelength and the bandwidth of the fiber grating can be tuned respectively through rotating the beam,namely,changing the position of the fiber grating.In the experiments,it is demonstrated the quasi-chirp-free wavelength tuning of(6.706 nm) and the broadest bandwidth tuning of(5.368 nm) in which the center wavelength is quasi-shift-free,moreover,the relation of center wavelength and bandwidth tuning with the force is linear,respectively.The experimental results are in good agreement with the theoretical analyses. |
| Keywords: | optoelectronics center wavelength tuning bandwidth tuning fiber Bragg grating loop thin-wall section beam |
