We have successfully established efficient coupling between two individual organic molecules by harnessing their strong coupling to a Fabry-Perot microcavity, thereby realizing the Tavis-Cummings model with dual emitters. This achievement is marked by the collective enhancement of the vacuum Rabi splitting, accompanied by the emergence of a distinctive dark middle peak. Our investigation further unveils the formation of subradiant/superradiant states within the dispersive regime of cavity quantum electrodynamics (QED), accompanied by a collectively enhanced Lamb shift in the superradiant state. Our work demonstrates the potential for achieving a high density of solid-state emitters with high individual cooperativity. This capability opens avenues for detecting rich, long range, coherent multi-photon intermolecular processes.
