“…These results confirm that the proposed plasmonic-photonic system is in the strong coupling regime. Although this splitting energy of 153 meV obtained in the visible regime is smaller than those in the infrared regime [11,19], it is much larger than those of many plasmonic-photonic strong coupling systems operating in the visible [15,[21][22][23]25,38].…”

We report the strong coupling between plasmonic surface lattice resonances (SLRs) and photonic Fabry-Pérot (F-P) resonances in a microcavity embedded with two-dimensional periodic array of metal-insulator-metal nanopillars. For such a plasmonic-photonic system, we show that the SLR can be strongly coupled to the F-P resonances of both the odd- and even orders, and that the splitting energy reaches as high as 153 meV in the visible regime. Taking advantage of the strong coupling, the resulted high-energy upper polariton has similar characteristics as the plasmonic SLR, but the quality factor is almost twice of that of the SLR. We expect that this work will provide a new scheme for strong coupling between plasmonic and photonic modes, and will point to a new direction to improve the quality factor of SLRs.

“…The splitting energy is 280 meV (85 nm linewidth), ( Figure a). In comparison with the passive plasmonic microcavities in which the splitting energy is only 70 meV, using fluorescent material film resulted in a considerable improvement of the coupling quality and strength and created a larger modal splitting on the coupled system.…”

in them are essential to explore the plasmonic behavior at various interfaces. Dielectric can be as inorganic and organic; its selection depends on their attributes. Presently organic materials are particularly attractive due to their long exciton lifetime which makes strong modal coupling in interaction with SPP probable. [4] To achieve strong coupling, organic material ought to possess limited transition linewidth [5] like using J-aggregate molecules at plasmonic interfaces. [6] But J-aggregate molecules require special environmental prerequisites to function properly and maintain stable interaction. In this study, we used small florescent molecule to investigate the strong modal coupling at the organic/ plasmonic interface. We focus on the strong modal coupling of plasmonic microcavity using florescent organic material, EY51 (Rubrene-like), in dielectric medium of plasmonic microcavity. The introduction of an active medium has effectively introduce a loss-compensated channel in the microcavity. We believe the interaction of active medium cavity and plasmonic nanostructure has generated a new plasmonic system that can open up a new degree to control modal coupling, analogous to the modal coupling control in parity-time symmetry system; we observed anticrossing with large Rabi-analog splitting at cavity mode-SPP coupling in large area hybrid plasmonic microcavity. We also investigated the luminescence intensity which acts as loss-compensation impact on the coupling strength of cavity. In addition, the photoluminescence (PL) emission measurement was carried out for plasmonic and photonic microcavity which acquired higher intensity of PL emission in the plasmonic cavity than that of photonic. The device was fabricated with conventional photolithography to provide the required practicality and cost-efficiency of mass production for various applications. [7] TheoryThe light-matter interaction at the plasmonic microcavity can be broadly described by the following Hamiltonian [8] cav c av spp s ppwhere ω cav and ω spp are, respectively, the resonant frequencies of the cavity mode and SPP mode, Γ cav and Γ spp represent the 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 paritytime symmetry characteristics.
