本文提出了一种新的光纤光栅制作方法——莫尔条纹振幅模板写入法。这种方法是采用莫尔条纹构成模板实现对写入光强的振幅调制，在硫化物光纤中写入周期为365nm的长周期光栅。这一方法可大大简化模板的制作工艺和降低成本，是一种使用方便、性能价格比优的方法。

A novel way to fabricate fiber grating using Moire pattern amplitude mask (MPAM)is described in this paper.The light beam intensity modulation for writing the grating on a fiber is performed by the amplitude mask with Moire pattern.And the LPG(Long Period Grating)is fabricated in chalcogenide fiber with period of 365nm.The technology is easy for making the mask and the cost can be reduced by this method.It is a good method of easy use and high performance with low price.
