Topological Frenkel exciton polaritons in one-dimensional lattices of strongly coupled cavities

Frenkel polaritons, hybrid light-matter quasiparticles, offer promise for the designing of new optoelectronic devices. However, their technological implementations are hindered by sensitivity to imperfections. Topology has been raised as a way to circumvent defects and fabrication limitations. Here, we propose a lattice of cavities to realize the one-dimensional Su-Schrieffer-Heeger model (SSH) for topological Frenkel polaritons. By engineering the configuration of the cavities we demonstrate that the SSH topological and trivial phases can be accessed, which we unravel by employing a dual approach based on classical and quantum theories. We study the role of inherent vibron modes and fabrication defects in the robustness of the topological phases of polaritons. Our study demonstrates a simple experimentally realistic setup to realize topological polaritons at room temperature.

Automated summary

Frenkel polaritons, hybrid light-matter quasiparticles, hold promise for optoelectronic device design, but their sensitivity to imperfections limits their implementation. Topology has been suggested as a solution to overcome defects and fabrication limitations. In this study, we propose a lattice of cavities to realize topological Frenkel polaritons based on the one-dimensional Su-Schrieffer-Heeger model. By engineering cavity configurations, we demonstrate access to both topological and trivial phases using classical and quantum theories. We analyze the impact of inherent vibron modes and fabrication defects on the robustness of polariton's topological phases. This study presents a simple, experimentally realistic setup for realizing topological polaritons at room temperature.
