摘　　要：设计了一种新型阵列光纤光栅的刻写系统,实现了8芯带状光纤上不同波长阵列光纤光栅的刻写。其基本原理如下：利用专门设计的带纤夹具夹持带纤,采用电控位移平台对带纤整体施加拉力来调节波长,逐根曝光,并采用扫描写入的方法进行汉明切趾。利用以上系统,实现了3 d B带宽为0.2 nm、波长间隔为0.5 nm、波长偏差小于±0.05 nm、反射率为80%~85%的阵列布拉格光纤光栅刻写。此工艺自动化程度高,光栅参数灵活可调。A kind of novel fabrication system of array optical fiber gratings is designed, which can make multi- wavelength array optical fiber gratings on 8-core ribbon optical fiber. The principle of this system is as follows： the ribbon optical fiber is clamped by the specially-designed fixture; tension is applied on ribbon optical fiber to control and change the resonant wavelength by electrically controlled displacement platform; optical fibers are exposed under ultraviolet （UV） laser one by one; Hamming apodization is employed at the same time. Array optical fiber Bragg gratings with 0.2 nm bandwidth, wavelength interval less than 0.5 nm, wavelength deviation less than ＋0.05 nm and reflectivigy from 80% to 85% on ribbon optical fiber are successfully obtained by the above system. This kind of technology is easy to adjust the parameters of the optical fiber gratings and has more automation.
