Lateral trenching for cross coupling suppression in integrated optics chips |
摘要 |
An optical waveguide network is formed in a substrate of an electrooptically active material. The optical waveguide has input and output facets where optical signals may be input to and output from the integrated optics chip. At least one lateral trench is formed in the substrate. The lateral trench is arranged to prevent light rays incident thereon from inside the substrate from propagating to the output facet. The lateral trench may be formed as a slot that extends toward the surface of the substrate where the optical waveguide network is formed, or the trench may be parallel to the plane of the optical waveguides. The trench may be formed in a surface that is either parallel or perpendicular to the plane of he optical waveguide network,
