Coherent excitations of intricate assemblies of molecules play an
important role in natural photosynthesis. Microcavities are
wavelength-dimension artificial structures in which excitations can be
made to couple through their mutual interactions with confined photon
modes. Results for microcavities containing two spatially separated
cyanine dyes are presented here, where simultaneous strong coupling of
the excitations of the individual dyes to a single cavity mode leads to
new eigenmodes, described as admixtures of all three states. These
"hybrid" exciton-photon structures are of potential interest as
model systems in which to study energy capture, storage, and transfer
among coherently coupled molecular excitations.
