Abstract :
Apodisation-generated in-band dispersion can limit the useful bandwidth of gratings. We discuss how a trade-off in reflection squareness may be necessary in order to increase the useful bandwidth. We show that apodisation-induced in-band dispersion can limit the useful bandwidth of gratings considered for current transmission systems. We discuss design rules depending on apodisation and length for an optimisation of the useful bandwidth
