| Abstract: | Chirped fibre Bragg gratings (CFBGs) are required to be concatenated to compensatethe fibre dispersion in the dense wavelength-division multiplexing (DWDM) systems.When the channel spacing is small, the performance of CFBGs is degraded, whichrestricts the usage of fibre gratings. The origin of the interactions between thegratings is analysed and methods of suppressing the interactions are also proposed. |
