  • Publication number: 20250020596
    Abstract: In certain examples, methods and semiconductor structures, aspects of the disclosure are directed to a guided-mode resonance metasurface pixel (“GMR pixel”) having a cavity section to support GMR at a certain Q and having optics at each end of the GMR pixel, to contain light and mitigate energy losses due to scattering of light, in response to light being directed towards the GMR pixel of the metasurface sensor. In certain more-specific examples, exemplary aspects of the disclosure are directed to a functionalized metasurface sensor including an array of guided-mode resonance metasurface biosensor pixels, each of which is functionalized for attachment of a distinct receptor or probe molecules.

  • Patent number: 12146826
    Abstract: A device for detecting optical chirality includes a metasurface composed of a biperiodic array of nanodisks in the form of a checkerboard array [300], where the nanodisks have diameters d±?/2 such that adjacent nanodisks [302, 304] have diameters that differ by an offset ?. The nanodisks are composed of a dielectric material that is transparent and has a refractive index greater than 2 at a predetermined operational ultraviolet wavelength. The nanodisks have a width-to-height aspect ratio d/h tuned to produce spectral overlap of electric dipole and magnetic dipole modes of incident circularly polarized ultraviolet light.

  • Publication number: 20230341384
    Abstract: Optical sensing of biological targets is provided using a metasurface having guided mode resonances with electric field profiles that extend out from the metasurface. Surface functionalization of such metasurfaces can be used to provide sensing for biological targets, such as nucleic acids, proteins, small molecules, extracellular vesicles, and whole cells. Binding of the target to the surface functionalization can affect the resonance wavelength of the guided mode resonances, thereby providing a sensitive assay for the biological targets.
