摘要
提出并分析了一种新型的布喇格光栅滤波器,用模式耦合方程分析了滤波器的传输特性,计算了通带宽度、自由谱宽和精细度。并把它用在以频移键控(FSK)方式调制的频分复用系统中,得到了比较理想的结果。
Abstract
The optical filter is a key device used to select frequency in the FDM and high density WDM optical fiber communication systems. In this peper, a novel Bragg grating fiber filter is reported. Its transmission characteristics, width of passband, free spectral rang and fineness are analysed by a coupled-mode theory. Also, We applied the filter to the FDM-FSK system and achieved good results.
