“…However, to give a full picture of light-matter interactions in strong coupling regime, particularly for the description of ultrafast coupling dynamics of a strongly coupled system, a quantum description is essentially required. For example, a strongly coupled system containing a quantum emitter, regarded as a two-level system resonant at ℏω 0 , embedded in an optical cavity with resonance energy of ℏω c can be described in a framework of Janeys-Cummings model with a Hamiltonian expressed as [84][85][86][87]:…”

Research efforts of light-matter in the nanoscale have focused on the manipulation of matter hybridized with photons under the strong coupling regime. Transition metal dichalcogenides (TMDs) have became ideal candidates for the study of strong light-matter interactions due to the formation of in-plane excitons exhibiting giant oscillator strength with narrow-band, well-pronounced optical transitions, which can be readily coupled to various optical excitations. The study of TMD-based strong coupling are leading to striking discoveries in many applications such as polariton condensation, lasing, all-optical switches and quantum information processing. This review summarizes the recent advances in strong coupling of TMD excitons with different types of nanostructures including traditional optical cavities, plasmonic nanocavities and all-dielectric nanoresonators. We finally discuss the future perspectives and possible directions on the TMD-based strong exciton-photon interactions in strong coupling regime.

“…The optical bistability in coupled optomechanical cavities in the presence of the Kerr effect has been studied, and it was found that the atomic medium has a profound effect on the bistable behavior of intracavity intensity for the optomechanical cavity. Meanwhile, a critical value for the Kerr coefficient to observe bistability in intracavity intensity of the optomechanical cavity is determined [20].…”

Optical bistability has been studied theoretically in a multi-mode optomechanical system with two mechanical oscillators independently coupled to two cavities in addition to direct tunnel coupling between cavities. It is shown that the bistable behavior of the mean intracavity photon number in the right cavity can be tuned by adjusting the strength of the pump laser beam driving the left cavity. In addition, the mean intracavity photon number is relatively larger in the red sideband regime than that in the blue sideband regime. Moreover, we show that the double optical bistability of the intracavity photon in the right cavity and the two steady-state positions of the mechanical resonators can be observed when the control field power is increased to a critical value. In addition, the critical values for the observation of bistability and double bistability can be tuned by adjusting the coupling coefficient between the two cavities and the coupling rates between cavity mode and mechanical mode.

“…Recently, researchers have extended single-cavity optomechanical systems to hybrid cavity optomechanical systems [11][12][13][14][15][16][17][18] by coupling more optical or mechanical modes, such as an atomic ensemble, a quantum well, a Kerr medium or other media with optomechanical cavities. More optical effects, such as electromagnetically induced transparency, [19][20][21][22][23][24][25][26] optical bistability, [27][28][29][30][31] slow light effects [32][33][34][35][36][37] and so on, have been extensively explored in these hybrid systems.…”

Controllable four-wave mixing response in a dual-cavity hybrid optomechanical system*

We systematically investigate the four-wave mixing (FWM) spectrum in a dual-cavity hybrid optomechanical system, which is made up of one optical cavity with an ensemble of two-level atoms and another with a mechanical oscillator. In this work, we propose that the hybrid dual-cavity optomechanical system can be employed as a highly sensitive mass sensor due to the fact that the FWM spectrum generated in this system has a narrow spectral width and the intensity of the FWM can be easily tuned by controlling the coupling strength (cavity–cavity, atom–cavity). More fascinatingly, the dual-cavity hybrid optomechanical system can also be used as an all-optical switch in view of the easy on/off control of FWM signals by adjusting the atom-pump detuning to be positive or negative. The proposed schemes have great potential applications in quantum information processing and highly sensitive detection.
