... For low power laser excitation, low k polariton states are found to have a very small population relative to those at high k. The bottleneck is found to be strongly suppressed at higher powers in the regime of superlinear emission of the lower polariton states. ... The subE linear behavior of the PL intensity at res 2.5 meV in Fig. 4 a is then explained by enhanced scattering out of these states by interparticle collisions, with some of these excitons scattering to populate the lower k states. ...

... Investigating both the biexciton and the single-exciton transition in the same single QD, we obtain a unified picture of the impact of electron-hole exchange interaction on the fine structure and the polarization properties of optical transitions in QDs. The exchange splitting is demonstrated to have a strong influence on the derivation of the biexciton binding energy, which we determine to be about 17 meV, much less than the separation between exciton and biexciton lines ( 24 meV) in the spectra. ...

... 114, 1329 ґ 1345 October 1998 The structure of the photon states and dispersion of cavity polaritons in semiconductor microcavities with two-dimensional optical confinement photon wires , fabricated from planar Bragg structures with a quantum well in the active layer, are investigated by measuring the angular dependence of the photoluminescence spectra. The size quantization of light due to the wavelength-commensurate lateral dimension of the cavity causes additional photon modes to appear. ...

... The gas-to-2D-liquid transition is evidenced by a strong screening of applied biases and by major changes in the optical spectra. ... Some indications of such an instability can be found in the PL spectra reported in Fig. 1 where, for 3 T 2.5 K, the I band of interwell excitons begins to move toward high energies and to broaden for decreasing T before vanishing below T c . ...

... The crystals have been fabricated out of a semiconductor microcavity by lateral etching of photonic wires with a 1D lattice of small holes in the top mirror stack along the wire axis. The photonic band structure of such photonic crystals has been shown to demonstrate very small photonic gaps and can be regarded as a set of modes with the dispersion curves being replicas of the photonic wire modes periodically shifted with an integer number of the Brillouin zone periods. ...

The observed strong reduction of the radiative decay rate in an in-plane magnetic field by more than 20 times in B 12 T, see Fig. 1 b also reflects the displacement of the interwell exciton dispersion and, correspondingly, the nonradiative character of the ground exciton state in a parallel magnetic field. ...
