  • Systems and methods for forming topological lattices of plasmonic merons
    Patent number: 12656689
    Abstract: Methods and systems for assembling electron spin and charge to possess one or more properties of a topological plasmonic spin texture array for performing lithography that is not limited by an optical system's diffraction limit are disclosed. According to one embodiment, the method includes defining a polarization of an optical field of light and a corresponding coupling-structure geometry. The method includes providing a coupling structure having the defined coupling-structure geometry in a metallic material, the coupling structure defining a region of the metallic material. The method includes directing light having the defined polarization to a center of the region, forming a lattice of plasmonic merons having a finer contrast resolution than a diffraction or reflection based resolution determined by Abbe limit based on the defined polarization of the optical field.
