METHOD AND APPARATUS FOR INTERCONNECTION OF OPTICAL WAVEGUIDE LAYERS

摘要

A method and apparatus for interconnection of optical waveguide layers. The apparatus for interconnection of optical waveguide layers comprises a source optical waveguide layer (11), a target optical waveguide layer (13), and a photonic crystal waveguide (12). One surface of the photonic crystal waveguide (12) is attached to one surface of the source optical waveguide layer (11), and the other surface of the photonic crystal waveguide (12) is attached to one surface of the target optical waveguide layer (13). The source optical waveguide layer (11) comprises a first vertical grating coupler (1101). The target optical waveguide layer (13) comprises a second vertical grating coupler (1301). The position of the first vertical grating coupler (1101) in the source optical waveguide layer (11) is the same as the position of the second vertical grating coupler (1301) in the target optical waveguide layer (13).
