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。
From the characteristics of Gires-Tournois (G-T) interferometer, a multi-channel dispersion compensation method based on G-T interferometer is analyzed. The method takes advantage of the periodicity of the dispersion curve of the G-T interferometer and simultaneously performs dispersion compensation on a plurality of communication wavelengths in a 1.55 μm window and achieves a dynamically tunable dispersion compensation amount.
