摘要
从Gires-Tournois(G-T)干涉仪的特性着手,分析一种基于G-T干涉仪的多信道色散补偿方法。该方法利用G-T干涉仪色散曲线的周期特性,同时对1.55μm窗口内的多个通信波长进行色散补偿,并实现色散补偿量的动态可调谐。
Based on theoretical analysis of the properties of Gires-Tournois (G - T) interferometer, a multi-channel chromatic dispersion compensation method using this interferometer is analyzed. This method takes advantage of periodic-like function of dispersion to produce large amount of negative dispersion to simultaneously compensate several channels' positive dispersion in 1.55 ?m window. And it can execute tunable chromatic dispersion compensation by slightly varying incident angle of the light or changing the length of G- T resonant.
