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 dB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 multiwavelength 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 technoloty is easy to adjust the parameters of the optical fiber gratings and has more automation.
