The paper reviews architectures, phenomena, and applications of strong light-matter coupling in hybrid polaritonic systems across inorganic, organic, and combined materials.
A machine-rendered reading of the paper's core claim, the
machinery that carries it, and where it could break.
This paper is a survey of polaritonics, the study of hybrid particles formed when light and matter interact very strongly. These polaritons combine properties of photons and material excitations, letting researchers influence how light behaves in materials, how electrons move, and even how chemical reactions proceed. The authors outline several physical setups that enable this strong coupling, such as tiny mirrored cavities for light, nanostructures that use surface plasmons, open cavities without full mirrors, and specially designed surfaces called metasurfaces. They cover materials ranging from inorganic semiconductors to organic molecular aggregates and hybrid combinations that reach strong or ultrastrong coupling regimes. Key ideas discussed include coherent time evolution of the hybrid states, interactions with molecular vibrations, dark states that store energy without emitting light, and how polaritons can shuttle energy or electrons across distances. The survey also touches on experimental and theoretical methods used to probe these systems and gives examples where strong coupling alters charge transport, energy transfer, and chemical reactivity. It closes by noting emerging regimes such as intermediate coupling and dark-strong coupling that expand the range of possible behaviors.
Core claim
Strong light-matter coupling gives rise to polaritons - hybrid excitations whose mixed photonic and matter character enables control over optical, electronic and chemical properties.
Load-bearing premise
That the selected architectures, phenomena, and examples comprehensively and accurately represent the current state of hybrid polaritonic systems without major omissions or biases in coverage.

Strong light-matter coupling gives rise to polaritons - hybrid excitations whose mixed photonic and matter character enables control over optical, electronic and chemical properties. This Feature Article surveys the main architectures supporting polariton formation, including photonic microcavities, plasmonic nanostructures, open cavities and metasurfaces, and outlines how inorganic semiconductors, organic aggregates and hybrid systems access strong and ultrastrong coupling. Key phenomena such as coherent dynamics, vibronic interactions, dark-state reservoirs and polariton-mediated energy and electron transport are discussed, together with the experimental and theoretical tools used to study them. We highlight examples where strong coupling modifies charge transport, energy flow and chemical reactivity, and we summarize emerging regimes, including intermediate and dark-strong coupling, that broaden the landscape of hybrid light-matter physics.
