Study of the surface lattice resonance on basis orientation for achieving ultrahigh quality factor > 12000

C. Liu, Joshua T. Y. Tse, H. C. Ong

Periodic nanoparticle arrays can support surface lattice resonances (SLRs), which arise from the hybridization between localized surface plasmons (LSPs) and diffractive Rayleigh an…

Determination of the Zak phase of one-dimensional photonic systems via far-field diffraction

Chao Liu, Haoran Wang, H. C. Ong

Bloch waves in 1D periodic systems carry Zak phase, which plays a key role in determining the band topology. In general, for systems that possess inversion symmetry, the Zak phase…

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…

Realization of topological superlattices and the associated interface states in one-dimensional plasmonic crystals

C. Liu, H. C. Ong

In analogous to the Su-Schrieffer-Heeger (SSH) model, one-dimensional (1D) electromagnetic (EM) crystals can exhibit nontrivial topological properties. In particular, when a nontri…

Small mode volume topological photonic states in one-dimensional lattices with dipole--quadrupole interactions

Raymond P. H. Wu, H. C. Ong

We study the topological photonic states in one-dimensional (1-D) lattices analogue to the Su-Schrieffer-Heeger (SSH) model beyond the dipole approximation. The electromagnetic res…

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…
