“…Thus the variation of length of the polymer area had to be less than the propagation length of the SPP which gives the intrinsic damping of the SPP; only lengths shorter than this are able to increase the damping even further. The results of [80] are presented in figure 13; these result have since been reproduced [168,169].…”

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.

“…In addition, the same was observed in our earlier measurements [ 18 ], where an energy transfer was also suggested to be the reason. In addition to the decreased luminescence, these scattering processes would significantly shorten the lifetime of the upper-branch-polaritons leading to the decrease of the Rabi energy of the higher split in D2, especially in the case of SR101, where larger couplings are achieved compared to the earlier measurements by Rhodamine 6 G [ 18 , 19 ]. Further, the strength of these processes is proportional to the coupling strength [ 32 ], which means that by increasing the concentration of SR101, the lifetime of the upper-branch-polaritons gets shorter (visible also as a widening of the linewidth of the upper branches in Figure 3 as the concentration increases).…”

Strong coupling between surface plasmon polaritons and Sulforhodamine 101 dye

We demonstrate a strong coupling between surface plasmon polaritons and Sulforhodamine 101 dye molecules. Dispersion curves for surface plasmon polaritons on samples with a thin layer of silver covered with Sulforhodamine 101 molecules embedded in SU-8 polymer are obtained experimentally by reflectometry measurements and compared to the dispersion of samples without molecules. Clear Rabi splittings, with energies up to 360 and 190 meV, are observed at the positions of the dye absorption maxima. The split energies are dependent on the number of Sulforhodamine 101 molecules involved in the coupling process. Transfer matrix and coupled oscillator methods are used to model the studied multilayer structures with a great agreement with the experiments. Detection of the scattered radiation after the propagation provides another way to obtain the dispersion relation of the surface plasmon polaritons and, thus, provides insight into dynamics of the surface plasmon polariton/dye interaction, beyond the refrectometry measurements.PACS: 42.50.Hz, 33.80.-b, 78.67.-n

“…Moreover, we consider the use of these nanoantenna structures to investigate strong coupling phenomena between surface plasmon polaritons (SPP) and quantum dots, related to our previous work on vacuum Rabi splitting for SPP and dye molecules. [7][8][9] This report consists of three main parts. First, the experimental and simulation methods are discussed, including the fabrication of such nanoantenna structures.…”
