The strong coupling regime is observed in a system of two-dimensional electrons whose cyclotron motion is coupled to an electromagnetic mode in a Fabry-Perot cavity resonator. Rabi splitting of eigenfrequencies of the coupled motion is observed both in the cavity reflection spectrum and ac current of the electrons, the latter probed by measuring their bolometric photoresponse. Despite the fact ...

Circuit QED1 is an approach for studying quantum optics in a superconducting integrated circuit. By combining a one-dimensional transmission-line cavity that stores microwave photons and a superconducting qubit that plays the role of an artificial atom, one can easily enter the strong coupling limit of cavity QED. In recent experiments, we attain couplings that are several percent of the qubit ...

Hybrid materials formed by plasmonic nanostructures and J-aggregates provide a unique combination of highly localized and enhanced electromagnetic field in metal constituent with large oscillator strength and extremely narrow exciton band of the organic component. The coherent coupling of localized plasmons of the multispiked gold nanoparticles (nanostars) and excitons of JC1 dye J-aggregates r...

We report the experimental observation of strong exciton–photon coupling in a planar microcavity composed of an organic semiconductor positioned between two metallic ~silver! mirrors. Via transmission and reflectivity measurements, we observe a very large, room temperature Rabi splitting in excess of 300 meV. We show that the Rabi-splitting is enhanced in all-metal microcavities by a factor of ...

The strong interaction of individual quantum emitters with resonant cavities is of fundamental interest for understanding light-matter interactions. Plasmonic cavities hold the promise of attaining the strong coupling regime even under ambient conditions and within subdiffraction volumes. Recent experiments revealed strong coupling between individual plasmonic structures and multiple organic mo...

Optical radiation properties of a single atom have been among the most popular research problems in quantum optics since the early years. In contrast to classical intuition, the quantum theory asserts that the optical radiation properties are not wholly determined by the intrinsic characteristics of the atom but also depend on the electromagnetic mode structure seen by the atom even when these ...

A single quantum emitter can possess a very strong intrinsic nonlinearity, but its overall promise for nonlinear effects is hampered by the challenge of efficient coupling to incident photons. Common optical materials, on other hand, are easy couple bulky, imposing severe limitation miniaturization photonic systems. In this work, we show that organic molecule acts as an extremely element in reg...
