Add-drop filters in silicon grating-assisted asymmetrie couplers

We demonstrate narrow-bandwidth (<; 1 nm) contradirectional couplers in silicon sidewall-modulated strip waveguides and slab-modulated rib waveguides, using a CMOS-compatible technology. They have box-like responses, low insertion losses, and no need of a circulator or isolator.
