Abstract: In this talk, I will present recent work on metamaterial, we have focused mainly on non-linear optics aspects and recently beginning to work on plasmonic devices with parity time symmetry (PTS) or PTS-like characteristics. We studied how active medium affects the Rabi-analogue 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 resulted in stronger modal coupling. Anti-crossing was observed with a large Rabi-analogue splitting energy of 280 meV in the strong coupling regime. The active medium contributed to the split enhancement through channeling more energy towards the coupling. The variation of photoluminescence emission and exciton-cavity mode coupling from the hybrid plasmonic microcavity were also measured. This work shows that by introducing an active medium in the microcavity, mode coupling between microcavity and surface plasmon polariton (SPP) can be enhanced and the hybrid plasmonic device exhibits parity time symmetry characteristics. Work is still in progress to further elucidate the device physics.

Keywords: Plasmonics, parity time symmetry, rabi-analogue split.
