Add-drop filters based on grating-assisted contra-directional couplers are investigated. It is shown that the implementation of the add-drop filter using strip waveguides with sidewall corrugated Bragg gratings results a stop-band with the central wavelength at 1.69 mm and a drop port wavelength at 1.56 mm. Moreover, the studied add-drop filter with rib waveguides shows the stop-band with the central wavelength at 1.58 mm and a drop port wavelength at 1.53 mm. In this case the gratings are corrugated on the sidewalls of the waveguides and between them. The drop port wavelength can be adjusted by altering the structural parameters.
