A wavelength mutiplexing/demultiplexing device based on chirped Moire fiber Bragg grating was analyzed theoretically. Using transfer matrix we get transmission spectrum and know that the CMGs have multiple flat passbands and show good channel spacings. By adjusting grating parameters, suitable channel spacings meeting the ITU's standard are obtained.%对基于啁啾Moire光纤布拉格光栅的波分复用/解复用器件进行了理论分析.用传输矩阵法计算了Moire光栅的透射谱特性,可知其透射谱具有多个通带及好的通道隔离度.通过调整光栅参数可获得通道间隔满足国际电信联盟标准的Moire光栅.
