    摘要: A method is used to fabricate a wide-angle Y-branch polarization splitters on lithium niobate crystal substrate. The Y-branch polarization splitter combines a straight waveguide with a substrate prism type wide-angle waveguide branch. The straight waveguide is a random polarization nickel diffusion waveguide. The branching waveguide is a proton exchanged waveguide. The fabrication technology needs only once of nickel diffusion and once of proton exchange. Due to the inherent property of single polarization for the proton exchanged waveguide, only the extraordinary polarization wave is bent and the ordinary wave remains in the straight waveguide. This results in a polarization splitter with high extinction ratio.

    摘要: We disclose a new optical TE-TM mode splitter on lithium niobate. The splitter is fabricated by using an asymmetric Y-junction structure which is composed of a straight waveguide, and two branch waveguides. The straight waveguide is the input one that can guide randomly-polarized light (i.e. both TE and TM modes). The two branch waveguides are the output ones, and one of them can guide only the TE mode, the other can guide only the TM mode. Because the output waveguides can individually guide the TE and TM modes, the input modes are then split by the branch waveguides. The input waveguide is fabricated by diffusing titanium into lithium niobate. The two output waveguides are made by nickel indiffusion and magnesium-oxide induced lithium outdiffusion or proton exchanged techniques.
