Strong coupling and the resultant mixing of light and matter states is an important asset for future quantum technologies. We demonstrate deterministic room temperature strong coupling of a mesoscopic colloidal quantum dot to a plasmonic nanoresonator at the apex of a scanning probe. Enormous Rabi splittings of up to 110 meV are accomplished by nanometer-precise positioning of the quantum dot with respect to the nanoresonator probe. We find that, in addition to a small mode volume of the nanoresonator, collective coherent coupling of quantum dot band-edge states and near-field proximity interaction are vital ingredients for the realization of near-field strong coupling of mesoscopic quantum dots. The broadband nature of the interaction paves the road toward ultrafast coherent manipulation of the coupled quantum dot-plasmon system under ambient conditions.

Gric, Hess O, 2017, Surface waves supported by the nanostructured semiconductor metamaterials, Journal of Electromagnetic Waves and Applications, ISSN: 0920-5071
We discover a new kind of surface wave on semiconductor nanostructured metamaterial, which crosses the light line with a substantial portion at lower frequencies lying above the free space light line. Interestingly, the propagation of such surface wave is found to be sensitive to the parameters of the semiconductor. Furthermore, the Ferrel-Berreman modes are observed under the certain conditions, opening a gateway toward device fabrications.

Kim T-T, Oh SS, Kim H-D, et al., 2017, Electrical access to critical coupling of circularly polarized waves in graphene chiral metamaterials., Sci Adv, Vol: 3
Active control of polarization states of electromagnetic waves is highly desirable because of its diverse applications in information processing, telecommunications, and spectroscopy. However, despite the recent advances using artificial materials, most active polarization control schemes require optical stimuli necessitating complex optical setups. We experimentally demonstrate an alternative-direct electrical tuning of the polarization state of terahertz waves. Combining a chiral metamaterial with a gated single-layer sheet of graphene, we show that transmission of a terahertz wave with one circular polarization can be electrically controlled without affecting that of the other circular polarization, leading to large-intensity modulation depths (>99%) with a low gate voltage. This effective control of polarization is made possible by the full accessibility of three coupling regimes, that is, underdamped, critically damped, and overdamped regimes by electrical control of the graphene properties.
