Far-field radiation of bulk, edge and corner eigenmodes from a finite 2D Su-Schrieffer-Heeger plasmonic lattice

\'Alvaro Buend\'ia, Jos\'e Antonio S\'anchez Gil, Jos\'e Luis Pura, Vincenzo Giannini

Antisymmetric modes in finite 2D SSH plasmonic lattices radiate less and achieve higher Q-factors than symmetric modes because out-of-plane dipoles cancel their far-field contributions.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We prove that the antisymmetric modes are darker and have higher Q-factors than their symmetric counterparts. Also, the out-of-plane nature of the dipolar resonances imposes that all bulk Γ-modes are dark, while corner and edge states need extra in-plane symmetries to cancel the far-field radiation.

C2weakest assumption

The coupled electromagnetic dipole formalism accurately captures the far-field radiation and Q-factors of the collective modes without needing higher-order multipoles or retardation effects beyond the model (implicit in the eigenmode analysis section of the abstract).

C3one line summary

Eigenmode analysis of a finite 2D Su-Schrieffer-Heeger plasmonic nanoparticle array shows that antisymmetric out-of-plane modes are darker with higher Q-factors, all bulk Gamma modes are dark, and radiation from edge/corner states becomes more in-plane concentrated as array size grows.
