为了实现一次性在八芯带纤上不同波长阵列光纤光栅刻写，采用专门设计的带纤夹具夹持光纤，使用电控位移平台对带状光纤整体施加拉力，利用相位掩膜工艺对光纤逐根曝光，采用扫描写入的方法进行汉明切趾，仅用单一相位模板就实现了八芯带纤上不同波长阵列布喇格光纤光栅刻写。刻栅过程由电脑编程控制，中心波长、波长间隔以及切趾方式可以灵活调整。结果表明，获得的光栅其3dB带宽为0．2nm、波长间隔为0．5nm、波长偏差小于±50 pm、反射率达到80％～85％。此种带状光纤多波长阵列光栅刻写工艺是完全可行的。

In order to inscribe multi-wavelength array fiber gratings in ribbon fiber including 8 fibers at the same time, ribbon fiber was fixed by a specifically designed fixture and tension was added to the whole ribbon fiber by a programmed control displacement platform .8 fibers in the ribbon fiber were exposed with phase mask technique one by one and Hamming apodization was realized simultaneously by using scan inscription method .Only with one phase mask , multi-wavelength array fiber gratings in the ribbon fiber including 8 fibers was achieved .The inscription process was controlled by the computer program .The central wavelength , the interval of wavelength and the style of apodization were adjusted freely . The test results of array Bragg fiber grating show that 3dB bandwidth is 0.2nm, wavelength interval is about 0.5nm, deviation is within ±50pm, and reflectivity can reach 80%~85%.Inscription technique for ribbon multi-wavelength array fiber gratings is entirely feasible .
