This paper describes a new method for designing flat-top cosine time windows. New perfectly flat-top windows, i.e., having monotonically decaying main lobe, and new equiripple flat-top windows, i.e., ...

An integrated-optics, flat-top drop-filter with low excess loss, and high sidelobe suppression ratio (SLSR), is demonstrated. The filter is based on apodized multimode waveguide Bragg grating (AMWBG) ...
