In this paper, a number of critical aspects in the design and performance of guided-wave grating-assisted tunable filters for dense telecommunications systems are investigated by using a rigorous numerical approach. It is shown how highly narrow filters, with the potential to be tunable over a large number of channels (> 50), can be accurately designed by using well-selected apodization windows.
