“…first observation of surface polariton splitting appears to be that due to Yakovlev et al [141], who looked at how the lattice vibrations (TO phonon mode) of a thin overlayer of LiF modified the surface phonon-polariton mode supported by an underlying rutile (T iO 2 ) substrate. Although the work of Yakovlev et al concerned phonon-polaritons rather than plasmon-polaritons, the similarity of the resulting dispersion curves, and of much of the underlying physics, makes this an important historical reference point.…”

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.

“…For thicker AlN films on sapphire such a splitting was observed in [13,14]. Note an interesting feature of the splitting under discussion: it is proportional to the square root of the film thickness [11,12] if the film dielectric function does not depend on the thickness. The angular dependencies of ATR minima show the dispersion curves for these samples (Fig.…”

“…One more minimum near 630 cm -1 in this figure belongs to the sapphire substrate. SP splitting due to the resonance with the transition layer vibrations was first predicted in [11] and experimen-tally demonstrated in [12] for LiF films on sapphire. For thicker AlN films on sapphire such a splitting was observed in [13,14].…”

The effect of annealing temperature on nitridation process of (0001) Al2O3 surface under ammonia flux was investigated by high‐energy electron diffraction and surface polaritons spectroscopy. High temperature annealing (≥1150 °C) of the surface results in the surface reconstruction √31×√31R±9° that inhibits the nitridation process. The external reflectivity infrared spectroscopy at near normal incidence angle is not sensitive to the annealing and nitridation. On the other hand, the high‐frequency minimum in the attenuated total reflection spectra splits near 700 cm–1 due to the surface reconstruction and/or the presence of aluminum nitride on the substrate surface, the splitting is sensitive to the surface treatment.

“…Vinogradov and Leskova [20] first reported observation of thermally excited radiation from such surface polaritons with negative group velocity in systems of ZnSe films on Al and Cr. Using a sapphire substrate covered by a thin film of LiF, Yakovlev et al [21] first observed the squire root dependence of the frequency gap on the film thickness L in the surface-polariton dispersion curve predicted by theory. The gap is expected to increase substantially as the resonant plasma frequency (and hence, o) moves up.…”
