Latest Patents

Rei-Shin Cheng holds a patent for the "Fabrication process of lithium niobate TE/TM polarization splitters." This patent describes a fabrication process for Y-branch nickel/zinc-indiffused polarization splitters on lithium niobate. The technology requires only two nickel/zinc indiffusions, one at a high temperature and the other at a lower temperature. The resulting nickel/zinc-indiffused waveguides can support single-ordinary, single-extraordinary, and random polarization waves, depending on the fabrication process parameters. High extinction ratios can be achieved due to the inherent single-polarization of the waveguides. The splitting ratios of the TE and TM modes are sufficiently high for practical applications. Rei-Shin Cheng has 1 patent to his name.
