Strong coupling between chlorosomes of photosynthetic bacteria and a confined optical cavity mode

Strong exciton-photon coupling is the result of a reversible exchange of energy between an excited state and a confined optical field. This results in the formation of polariton states that have energies different from the exciton and photon. We demonstrate strong exciton-photon coupling between light-harvesting complexes and a confined optical mode within a metallic optical microcavity. The energetic anti-crossing between the exciton and photon dispersions characteristic of strong coupling is observed in reflectivity and transmission with a Rabi splitting energy on the order of 150 meV, which corresponds to about 1,000 chlorosomes coherently coupled to the cavity mode. We believe that the strong coupling regime presents an opportunity to modify the energy transfer pathways within photosynthetic organisms without modification of the molecular structure.

Higher radial modes of azimuthal surface waves in magnetoactive cylindrical plasma waveguides

2018

Azimuthal surface waves are eigenmodes of cylindrical plasma–dielectric–metal structures both in the presence of and without an axial static magnetic field. They are actively studied due to possible applications in plasma electronics, nanotechnologies and biomedical diagnostics. Higher radial modes are known to propagate at higher frequencies and shorter wavelengths compared to those of the zeroth mode, a feature which is of interest for practical applications. To gain the advantage of the excitation of higher radial modes of azimuthal surface waves one has first to know their dispersion properties. This paper generalizes the results of earlier papers by including a static axial magnetic field and considering the higher radial modes. The presence of the constant axial magnetic field removes the degeneracy in the wave spectrum with respect to the sign of the azimuthal wavenumber.

to hybridize excitonic resonances associated with two different species. [17,18,15] Hybridization of different vibrational overtones of an excitonic resonance of a single molecular species has also been achieved. [19,20] Meanwhile, in the infrared regime, hybridization of vibrational resonances associated with two distinct molecular species has also been reported recently. [21,22] While hybridization of two different vibrational resonances of a single molecular species to a cavity mode were reported by George et al. [23] Here we present results of experiments that show hybridization of three vibrational resonances of a single mode species to first a cavity mode and second a surface plasmon mode, thereby adding a potentially important component in the strong coupling toolbox, one that may further the degree of control possible over molecular vibrational states in any future polaritonic chemistry.Strong coupling of vibrational modes was first explored using a planar cavity filled with the polymer polymethyl-methacrylate (PMMA) where the cavity mode was strongly coupled to the CO vibrational resonance in the polymeric material. [24,25] Several further investigations have since been reported, [26][27][28][29][30][31][32][33] involving vibrational resonances in liquids, [34] transition metal complexes, [33] and liquid crystals. [35] Strong coupling of vibrational resonances has also been reported to help catalyze and inhibit chemical reactions [36] and to control the nonlinear optical response in the infrared. [37] 2D spectroscopy of molecular vibrations in an optical microcavity has also been explored. [38,39] In the present work, we make use of two different types of confined light field. First we use the well-established planar optical microcavity, second we make use of the surface plasmon mode associated with a single metal surface. Surface plasmons on planar metal films have momenta that cannot be accessed easily by incident light; therefore, we employ grating coupling to overcome this problem, an approach previously explored for strong coupling of excitonic resonances. [40,41] In what follows, we briefly describe the sample structure and material properties. The main probe we use to explore the coupling between vibrational resonances and the optical modes of our confined light fields is to determine the dispersion of the polaritons involved. We describe how these data are acquired and present results from both types of cavity. We then discuss the modeling we have undertaken, both numerical and analytical, before summarizing our findings. Results and DiscussionSchematics of the structures we used are shown in Figure 1. The optical microcavity was based on two gold mirrors 12 nm Strong coupling of molecules placed in an optical microcavity may lead to the formation of hybrid states called polaritons, states that inherit characteristics of both the optical cavity modes and the molecular resonance. This is possible for both excitonic and vibrational molecular resonances. Previous work has shown that strong coupling...
