Opis:: In this work, we discuss theoretically the formation of the Tamm plasmon/exciton-polariton hybrid states in an (Al,Ga)As microcavity and their modulation by surface acoustic waves. The modulation of the Tamm plasmon/exciton-polariton states origins in the change of the excitonic band gap energy and the thickness change of the sample structure layers due to the induced strain fields by surface acoustic waves. The frequency f_{SAW} of the acoustic modulation of the Tamm plasmon/exciton-polariton states is limited by the thickness of the upper distributed Bragg reflector. For the Tamm plasmon/exciton-polariton states in Al_xGa_{1-x}As/GaAs structures f_{SAW} is in the range of 370 MHz while f_{SAW} in GHz range is possible for the parametric Tamm plasmon/exciton-polariton states. In both cases, the acoustic modulation is several meV for typical acoustic power levels.

Opis:: Semiconductor microcavities are monolithic multilayer heterostructures grown by molecular beam epitaxy. They allow the confinement along the growth axis of both photons between the Bragg reflectors and excitons in quantum wells. If the exciton-photon coupling matrix element is large enough compared to the line width, the system is said to be in the strong coupling regime. In that case a quantum well exciton couples to another discrete state: the photon mode of a planar microcavity with the same in-plane wave vector, to give rise to quasi-stationary states named cavity polaritons. In this regime, the Fermi golden rule does not hold any more and the optical properties, linear or nonlinear, are strongly related to polariton features. A review of the optical properties of CdTe-based microcavities operating in the strong coupling regime is given in this paper. The strength of the exciton-photon coupling, dynamic optical properties, and relaxation processes along polariton dispersion curves will be discussed, as well as stimulated emission of cavity polariton luminescence.

Opis:: We report on cw optical experiments performed in a semiconductor microcavity containing a single quantum well in the strong coupling regime. Angularly resolved photoluminescence measurements under non-resonant excitation show the collapse of a relaxation bottleneck as the excitation power is increased. As a result, the emission close to k$\text{}_{∥}$=0 presents a non-linear behavior. In a two-beam experiment we resonantly inject polaritons at k$\text{}_{∥}$=0 and show that relaxation from states with large in-plane wave vector toward k$\text{}_{∥}$=0 is stimulated by the polariton final state population.

Opis:: The influence of magnetic field on confined exciton-polariton modes inside a semiconductor microcavity is discussed. The three-dimensional confinement for exciton-polaritons is achieved by the mesa structures confining the photonic part of polaritons. We observe a strong increase of the polariton emission intensity and we argue that this effect is due to the change of the oscillator strength of the excitonic component of polaritons and the change of the excitonic content in polariton state as the magnetic field increases.
