    Notes: Summary Our interest is centred on the very thin layers consisting of only one or a few monolayers of InAs. The optical transition energies, measured by photoluminescence spectroscopy, are compared with theoretical calculations obtained in envelope function approximation and through an empirical tight-binding method. This comparison yields values for the not well-known valence band offset at the InAs/InP interface, and the luminescence lines observed at different energies could be assigned to layers between one and 13 monolayers thick.

    Notes: Summary A description of polariton effects on excitons in multiple quantum wells (MQWs), superlattices (SLs), and semiconductor microvavities is presented. The non-local semi-classical theory in a transfer matrix formulation is adopted. The radiative width in MQWs atk=0 increases first with the number of wellsN, then goes to zero asN→∞, where stationary SL polaritons are recovered. The crossover from weak- to strong-coupling regimes for QW excitons in microcavities is described. The complex energies of the mixed exciton-radiation modes are shown to be measurable by time-resolved transmission experiments.

    Notes: Summary We study excitons in double quantum wells (DQWs) embedded in a semiconductor microcavity (MC) by means of semi-classical theory, which yields analytic results in weak- and strong-coupling regimes. We show how to obtain subpicosecond radiative lifetime for the excitons. A model for disorder is investigated.

    Notes: Summary A quantum-mechanical model for quantum well polaritons in semiconductor microcavities is presented. The real and imaginary parts of the polariton dispersion are obtained. They represent, respectively, the position and the linewidth of the luminescence peaks observed in typical experiments. The model includes the features of the distributed Bragg reflectors which constitute the cavity mirrors, and has the advantage of describing the weak-coupling as well as the strong-coupling regimes characteristic of this kind of systems. Furthermore, in the limit where no cavity is present, the well-known result for quantum well polaritons is recovered.

    Description / Table of Contents: Riassunto Si presentano le soluzioni esatte del problema quantistico del polaritone con dispersione spaziale. Gli autostati polaritonici esatti sono ottenuti come combinazioni di stati fotonici e di stati di polarizzazione. Contributi non lineari di fotoni e di quanti di polarizzazione sono presenti a tutti i valori dik. Componenti a due fotoni e a tre fotoni sono date in forma esplicita.
    Notes: Summary We give the exact solution of the quantum polariton problem with spatial dispersion. The exact polariton eigenstates are obtained in terms of photon and polariton states. For all values ofk a nonlinear contribution of the photon and polarization states is present in the polariton wave function. Two- and three-photon components are explicitly singled out.
