WebSuch a grating can recover the 10-Gb/s signal by compensating the GVD acquired over 400 km of the standard fiber. The chirped grating should be apodized in such a way that the coupling coefficient peaks in the middle but vanishes at the grating ends. The apodization is essential to remove the ripples that occur for gratings with a constant κ.
WebChirped gratings can be obtained in different ways, e.g. with point-to-point laser inscribing, with chirped phase masks or by tapering the fiber after writing the grating.
