Realization of superchiral surface lattice resonances in three-dimensional bipartite nanoparticle arrays
Joshua T. Y. Tse, H. C. Ong
Optical chirality (OC) is a fundamental property of electromagnetic waves that plays a key role in governing chiral light-matter interaction. Here, we demonstrate how to obtain sup…
Quality factor of plasmonic monopartite and bipartite surface lattice resonances
Joshua T. Y. Tse, H. C. Ong
Surface lattice resonance (SLR) is the collective excitation of nanoparticle resonances arising from the hybridization between localized surface plasmons (LSPs) and propagating Ray…
Generalization of the circular dichroism from metallic arrays that support Bloch-like surface plasmon polaritons
X. Guo, C. Liu, H. C. Ong
The broken mirror symmetry in subwavelength photonic systems has manifested many interesting chiroptical effects such as optical rotation and circular dichroism. When such systems…
Polarization conversion of non-specular diffraction orders from metallic nanohole arrays studied by Fourier space polarimetry
Z. L. Cao, K. Ding, L. Y. Yiu +3
We use Fourier space polarimetry to study the incident angle- and polarization-dependent rotation angle and ellipticity of different diffraction orders emerging from a two-dimensio…
Structural Symmetry of Two-dimensional Metallic Arrays: Implications for Surface Plasmon Excitations
H. Iu, H. C. ong, Jones T. K. Wan
In recent years, there has been intensive investigation of surface plasmon polaritons (SPPs) in the science and engineering fields. Understanding the physics of surface plasmon exc…
