Plasmonic elliptical nanoholes for chiroptical analysis and enantioselective optical trapping

no code implementations • 12 Jan 2021 • Zhan-Hong Lin, Jiwei Zhang, Jer-Shing Huang

Under linearly polarized excitation, an elliptical nanohole in a thin gold film can generate a localized chiral optical field for chiroptical analysis and simultaneously serve as a near-field optical trap to capture dielectric and plasmonic nanospheres.
