摘要

为改变光纤光栅的写入Bragg波长

研制了包括一块相位模板和两块紫外反射平面镜的楔块调整式Talbot干涉仪。在写入光纤Bragg光栅的过程中

通过调整两平面镜的反射角度可改变由±1级衍射光束经两平面镜反射后形成的干涉条纹的周期。最后

放置在可调谐干涉区的光纤就可刻写成具有不同写入Bragg波长的光纤光栅。值得注意的是通过选择不同倾斜角α的楔形块

决定了光纤光栅的写入Bragg波长的改变率和干涉条纹棱脊位置的位移率。

Abstract

A wedge-adjusted Talbot interferometer

which includes one phase mask and two UV-reflected mirrors

has been developed to change the process of writing fiber Bragg grating. The interference fringe period formed by the ?1 order diffractive beams is changed by adjusting the reflected angles of two mirrors

and the fiber placed in the tuned interference fringe can then be fabricated to the fiber Bragg grating with various inscribed Bragg wavelengths. The changing ratio of the inscribed Bragg wavelengths and the displacement ratio of the diamond bridge of interfering fringe can be defined by selecting the wedges with different tilt angles.
