“…An interesting feature of R6G is that it has strongly overlapping monomer and dimer (aggregate) absorption and emission bands [163,164]. Moreover, the monomer absorption and emission spectra have a double-peaked structure (i.e.…”

Abstract. In this review we look at the concepts and state-of-the-art concerning the strong coupling of surface plasmon-polariton modes to states associated with quantum emitters such as excitons in J-aggregates, dye molecules and quantum dots. We explore the phenomenon of strong coupling with reference to a number of examples involving electromagnetic fields and matter. We then provide a concise description of the relevant background physics of surface plasmon polaritons. An extensive overview of the historical background and a detailed discussion of more recent relevant experimental advances concerning strong coupling between surface plasmon polaritons and quantum emitters is then presented. Three conceptual frameworks are then discussed and compared in depth: classical, semi-classical and fully quantum mechanical; these theoretical frameworks will have relevance to strong coupling beyond that involving surface plasmon polaritons. We conclude our review with a perspective on the future of this rapidly emerging field, one we are sure will grow to encompass more intriguing physics and will develop in scope to be of relevance to other areas of science.

“…k (10 m ) It should be noted that the high molecular concentration of our samples together with the tendency of R6G to form aggregates, particularly dimers [30,31], implies that the possible dimer contribution to the energy splits cannot be neglected. The R6G dimer absorption in solid matrices forms two bands, H and J: the absorbance maximum of the H band overlaps with the monomer shoul-der, whereas the absorbance of the J band is strongly redshifted with respect to monomer maximum [31].…”

We report on strong coupling between surface-plasmon polaritons (SPP) and Rhodamine 6G (R6G) molecules, with double vacuum Rabi splitting energies up to 230 and 110 meV. In addition, we demonstrate the emission of all three energy branches of the strongly coupled SPP-exciton hybrid system, revealing features of system dynamics that are not visible in conventional reflectometry. Finally, in analogy to tunable-Q microcavities, we show that the Rabi splitting can be controlled by adjusting the interaction time between waveguided SPPs and R6G deposited on top of the waveguide. The interaction time can be controlled with sub-fs precision by adjusting the length of the R6G area with standard lithography methods.

“…The location of the lower energy split coincides with the R6G absorption maximum, and the higher energy one is close to a shoulder in the R6G absorption spectrum. 19 The double split does not show in the result of our calculation, as shown in Fig. 4, since the calculated effective refractive index for the PMMA+R6G layer is based on an absorption measurement of R6G in solution.…”

“…However, R6G is known to form aggregates easily, of mostly dimers, which results in an additional absorption maximum that strongly overlaps with the absorption shoulder of the monomer. 10,19 The samples in Figs. 5 and 6 may contain a considerable amount of dimers in addition to monomers, contributing to the strong splitting observed around 4·10 15 rad/s.…”

We report on strong coupling between surface-plasmon polaritons and Rhodamine 6G molecules at room temperature. As a reference to compare with, we first determine the dispersion curve of (uncoupled) surface plasmon polaritons on a 50 nm thick film of silver. Consequently, we determine the dispersion curve of surface plasmon polaritons strongly coupled to Rhodamine 6G molecules, which exhibits vacuum Rabi splitting. Depending on the Rhodamine 6G concentration, we find splitting energies between 0.05 eV and 0.13 eV.
