Submitted for the MAR14 Meeting of The American Physical Society Large vacuum Rabi splitting for a semiconductor nanogap cavity MITSUHARU UEMOTO, HIROSHI AJIKI, Osaka University — A metallic nanogap utilizing surface plasmon excitation is one of the most popular designs of an optical antenna converting propagating radiation into enhanced fields at a nanoscale area (hotspot). Similarly, a nanoga...

In this Comment, we challenge the main claims made by Toida et al. [1] and demonstrate that their results do not provide direct evidence of vacuum Rabi splitting or vacuum Rabi oscillations. In contrast to statements made by Toida et al., the two sharp parallel structures in Fig. 3(b) of [1] are not indicative of a coherent quantum mechanical interaction. Instead, as shown in previous work [2,3...

We demonstrate coherent tunable coupling between a superconducting phase qubit and a lumped-element resonator. The coupling strength is mediated by a flux-biased rf SQUID operated in the nonhysteretic regime. By tuning the applied flux bias to the rf SQUID we change the effective mutual inductance, and thus the coupling energy, between the phase qubit and resonator. We verify the modulation of ...

We report on strong coupling between surface-plasmon polaritons (SPP) and Rhodamine 6G (R6G) molecules, with double vacuum Rabi splitting energies up to 230 and 110 meV. In addition, we demonstrate the emission of all three energy branches of the strongly coupled SPP-exciton hybrid system, revealing features of system dynamics that are not visible in conventional reflectometry. Finally, in anal...

All-solid-state strong light-matter coupling systems with large vacuum Rabi splitting are great important for quantum information application, such as quantum manipulation, quantum information storage and processing. The monolayer transition metal dichalcogenides (TMDs) have been explored as excellent candidates for the strong light-matter interaction, due to their extraordinary exciton binding...

Wide bandgap semiconductors are promising materials for the development of polariton-based optoelectronic devices operating at room temperature (RT). We report the characteristics of ZnO-based microcavities (MCs) in the strong coupling regime at RT with a vacuum Rabi splitting of 72 meV. The impact of scattering states of excitons on polariton dispersion is investigated. Only the lower polarito...

We discuss the vacuum Rabi splitting (VRS) from multilevel atoms under electromagnetically induced transparency condition within the framework of linear absorption-dispersion theory. Sharp resonance features superimposed on usually occurring VRS doublet to three-peaked structure spectra are obtained here which can be engineered to have absorptive, dispersive, or dip like profiles according to t...
