Here it is studied how the active medium affects the Rabi-analog splitting when an active plasmonic microcavity mode is coupled to a surface plasmon polariton mode. The incorporation of Rubrene-like molecules in the plasmonic microcavity results in stronger modal coupling. Anticrossing is observed with a large Rabi-analog splitting energy of 280 meV in the strong coupling regime. The active medium contributes to the split enhancement through channeling more energy toward the coupling. The variation of photoluminescence emission and exciton-cavity mode coupling from the hybrid plasmonic microcavity are also measured. This work shows that by introducing an active medium in the microcavity, mode coupling between microcavity and surface plasmon polariton can be enhanced and the hybrid plasmonic device exhibits parity–time symmetry characteristics.
