Abstract :
Results for a new dielectric-waveguide (DW) channel dropping filter are presented. The DW channel dropping filter is composed of 3 dB directional couplers and bandstop gratings. This class of channel dropping filters yields much wider bandwidth than ring resonator type channel dropping filters
