“…This regime has been studied previously to prepare, e.g., non-classical states in the micromaser. In the visible frequency band, the regime is accessible for microlasers with high-Q cavities [20,21].…”

Abstract. We discuss the laser theory for a single-mode laser with nonlinear gain. We focus in particular on a micromaser which is pumped with a dilute beam of excited atoms crossing the laser cavity. In the weak-coupling regime, an expansion in the coupling strength is developed that preserves the Lindblad form of the master equation, securing the positivity of the density matrix. This expansion breaks rapidly down above threshold. This can be improved with an alternative approach, not restricted to weak coupling: the Lindblad operators are expanded in orthogonal polynomials adapted to the probability distribution for the atom-laser interaction time. Results for the photon statistics and the laser linewidth illustrate the theory.

“…Moreover, the EM environment of fluorophore can be changed by strong coupling [77], so it can be used to change the threshold of the chemical reaction and control the rate of chemical reactions. The strong coupling of superconducting quantum bits and microwave can be applied to routers [78], photon detectors [79], and single-photon switches [80].…”

Abstract:The interaction of exciton-plasmon coupling and the conversion of exciton-plasmon-photon have been widely investigated experimentally and theoretically. In this review, we introduce the exciton-plasmon interaction from basic principle to applications. There are two kinds of exciton-plasmon coupling, which demonstrate different optical properties. The strong exciton-plasmon coupling results in two new mixed states of light and matter separated energetically by a Rabi splitting that exhibits a characteristic anticrossing behavior of the exciton-LSP energy tuning. Compared to strong coupling, such as surface-enhanced Raman scattering, surface plasmon (SP)-enhanced absorption, enhanced fluorescence, or fluorescence quenching, there is no perturbation between wave functions; the interaction here is called the weak coupling. SP resonance (SPR) arises from the collective oscillation induced by the electromagnetic field of light and can be used for investigating the interaction between light and matter beyond the diffraction limit. The study on the interaction between SPR and exaction has drawn wide attention since its discovery not only due to its contribution in deepening and broadening the understanding of SPR but also its contribution to its application in light-emitting diodes, solar cells, low threshold laser, biomedical detection, quantum information processing, and so on.

“…Of particular interest is the strong coupling regime, where the dressed states basis becomes the relevant one to describe and understand the coupled system. Historic experiments of quantum electrodynamics have been realized using a few atoms in the strong coupling regime with a few cavity photons [1,2]. In strong analogy, three groups have recently reported the successful achievement of strong coupling regime for one single Quantum Dot (QD) with a high-quality factor (Q) cavity mode [3][4][5].…”

We present a novel semiconductor structure in which 0D polaritons coexist with 2D microcavity polaritons. Spatial trapping of the 2D microcavity polaritons results from the confinement of their photonic part in a potential well, consisting of an adjustable thickness variation of the spacer layer. This original technique allows to create polaritonic boxes of any size and shape. Strong coupling regime is evidenced by the typical energy level anticrossing, in real space and in momentum space, and supported by a theoretical model.Semiconductor heterostructures allow the analysis of light-matter interaction in nanoscopic or mesoscopic systems, in which properties of both uncoupled light and matter oscillators can be strongly engineered. Beyond the motivation of the realization of optoelectronic devices, monitoring of light by matter and vice versa has already led to a wide range of new fascinating physics. Of particular interest is the strong coupling regime, where the dressed states basis becomes the relevant one to describe and understand the coupled system. Historic experiments of quantum electrodynamics have been realized using a few atoms in the strong coupling regime with a few cavity photons [1,2]. In strong analogy, three groups have recently reported the successful achievement of strong coupling regime for one single Quantum Dot (QD) with a high-quality factor (Q) cavity mode [3][4][5]. In these systems the small number of electronic excitations opens the way to the realization of solid state devices for quantum information operation.Research on solid state systems has also been motivated, during the last 50 years, by the possibility to achieve Bose-Einstein condensation (BEC) at high temperature. This effect involves a huge number of particles, that massively accumulate into a single quantum state below a critical temperature, thus displaying macroscopical quantum properties. To reach this goal, the most promising candidates are microcavity polaritons, eigenstates of semiconductor microcavities in strong coupling regime [6]. These quasiparticles have the great advantage over excitons to exhibit a very light effective mass. Their bosonic behavior at low density has been demonstrated already by final state stimulation in parametric scattering process [7], and by direct evidence of quantum degeneracy [8]. Rather high temperatures have been reached for such effects [9]. However, polariton BEC has not been demonstrated yet. A more favorable situation for BEC should be obtained by confining the polaritons within a small volume, as suggested by
