Abstract
The dispersive properties of the single and cascaded fiber gratings have been discussed and analyze.A transmission-based dispersion compensator employing cascaded fiber gratings for dispersion compensation of multiple channels WDM lightwave systems has been proposed correspondingly in the paper.The results show that the effective compensation can be achieved if the parameters of cascade fiber gratings are chosen carefully.
