Latest Patents
Yu-Pin Liao's latest patents include a "Structure and method for fabricating a wide-angle TE-TM mode splitter." This invention utilizes a method to create a wide-angle Y-branch polarization splitter on a lithium niobate crystal substrate. The design integrates a straight waveguide with a substrate prism type wide-angle waveguide branch. The straight waveguide employs a random polarization nickel diffusion waveguide, while the branching waveguide is a proton exchanged waveguide. This innovative fabrication process requires only one instance of nickel diffusion and one of proton exchange. The unique properties of the proton exchanged waveguide allow for the bending of only the extraordinary polarization wave, resulting in a high extinction ratio for the polarization splitter.
Another significant patent is the "Fabrication process of lithium niobate TE/TM polarization splitters." This process details the creation 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 resulting nickel/zinc-indiffused waveguides can support various polarization waves, achieving high extinction ratios due to their inherent single-polarization characteristics. The splitting ratios of the TE and TM modes are sufficiently high for practical applications.
