“…On top of this approximation a so-called common-mode approximation is proposed [86] where only waveguide modes with the same mode numbers are coupled across interfaces. For the case of large diameters ( 2λ ≥ ), the results with and without the common-mode approximation are almost identical [55,[83][84][85].…”

“…However, the peak reflectivity was limited to values below 99% in these cases. The achievement of fully monolithic ZnSebased MCs is presented in [53][54][55] for the first time. Other reports treat ZnSe-based micro-disk resonators with quantum wells [56] and CdSe QDs embedded [57,58].…”

“…A good method to fabricate high quality cylindrically shaped pillar MCs with diameters down to 500 nm was developed using focused-ionbeam (FIB) etching [54,55]. Scanning electron microscope (SEM) images of the resulting structures with 3.5 µm and 500 nm diameter (measured by SEM in the height of the cavity) are shown in Fig.…”

“…Available methods are mode expansion techniques [67][68][69][70][71], boundary element methods [72][73][74] and volume element methods [75][76][77][78]. For micropillar cavities, the FDTD method [79,80] and mode expansion techniques [55,[81][82][83][84][85] are commonly used. The latter kind of method naturally leads to a vectorial transfermatrix approach.…”

1 Introduction In the last years new ways to manipulate the light-matter interaction were found by modifying photonic components which confine light on the wavelength scale by means of semiconductor microcavities (MCs) [1]. The modified optical density of states produced by photonic structuring allows emission and absorption rates to be enhanced or suppressed. This is known as the Purcell effect which can be used to control the spontaneous emission [2]. Semiconductor MCs appear to a be highly attractive systems for the realization of a new generation of optoelectronic devices, polariton devices, optical switches and spin-memory elements. Several types of solid state MCs [1], including micropillars [3,4], microdisks [5,6] and photonic crystals [7,8], offer very small mode volumes V in combination with high quality factors Q. These factors describe the ability of the cavity to confine the light.

“…The strong coupling being clearly demonstrated, we got interested into characterizing the 0D polaritons in real and reciprocal space. Figure 2(b) is a spatially resolved spectrum [19] of a 15 µm stripe of the sample surface (horizontal axis) containing a 3 µm diameter mesa, non-resonantly excited by a 2 µm diameter laser spot. The stripe axis was chosen perpendicular to the wedge in order to prevent non-intrinsic …”

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
