摘要：

The contra-directional coupling between two stacked thin film waveguides by grating couplers is studied, In this scheme, a guided mode of the first-story waveguide is coupled by a grating coupler to radiation modes, and the radiation modes are coupled by another grating coupler to a guided mode propagating contra-directionally in the second-story waveguide, A device for demonstration was designed, fabricated and characterized at 800 nm coupling wavelength. A very sharp wavelength selectivity of 0.3 nm FWHM was experimentally confirmed with 1 mm coupling length. (C) 1997 Elsevier Science B.V.
