Abstract
Chirped fiber Bragg gratings are supposed to be cascaded for multi-channel dispersion compensation in DWDM systems. The interaction between them restricts their employment. Gaussian and Super Gaussian apodization are used to reduce the out-of-band reflection so as to suppress the interaction of the cascaded gratings. The increase of the channel spacing can also diminish the interaction.
