Latest Patents
One of Ruei-Chang Lu's latest patents is titled "Structure and method for fabricating a wide-angle TE-TM mode splitter." This invention describes a method for fabricating a wide-angle Y-branch polarization splitter on a lithium niobate crystal substrate. The Y-branch polarization splitter integrates a straight waveguide with a substrate prism type wide-angle waveguide branch. The straight waveguide is a random polarization nickel diffusion waveguide, while the branching waveguide is a proton exchanged waveguide. The fabrication process requires only one instance of nickel diffusion and one of proton exchange. Due to the unique properties of the proton exchanged waveguide, only the extraordinary polarization wave is bent, while the ordinary wave remains in the straight waveguide. This results in a polarization splitter with a high extinction ratio.
Another significant patent by Lu is the "Fabrication process of lithium niobate TE/TM polarization splitters." This process outlines the fabrication of Y-branch nickel/zinc-indiffused polarization splitters on lithium niobate. The technology involves two nickel/zinc indiffusions, one at a high temperature and the other at a lower temperature. The nickel/zinc-indiffused waveguides can support single-ordinary, single-extraordinary, and random polarization waves, depending on the fabrication parameters. High extinction ratios are achievable due to the inherent single-polarization characteristics of the waveguides, making them suitable for practical applications.
