The results show that it is suitable to write azopolymer long-period optical fiber gratings using the polarization direct writing method and amplitude mask method.

结果表明：目前比较适合用于偶氮苯聚合物长周期光纤光栅刻写的方法有偏振直写法和振幅掩模法两种。

We inscribed surface relief grating on the thin films using Point-by-Point method and amplitude mask method (the amplitude mask was taken place by grating roll film manufactured by ourselves).

利用逐点写入法和振幅掩模法(振幅掩模板为自制光栅胶片)在这种薄膜上刻写了表面形貌光栅。
