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。
Theoretical analysis of the WDM / Demultiplexer based on chirped Moire fiber Bragg grating is carried out. The transmission matrix was used to calculate the transmission spectrum of the Moire grating. The transmission spectrum showed multiple pass bands and good channel isolation. Moire gratings with channel spacing meeting the International Telecommunication Union standards can be obtained by adjusting the raster parameters.
