  text: The evolution of the quantum mechanical phase of electronic wave packets on
    seattering-with phonons is an issue of great relevance in solid-state physics.
    In semiconductor superlattices, evidence for phase conservation on scattering
    was obtained when time-resolved THz-emission experiments indicated that the dephasing
    of the probed intraband coherence may proceed slower than the relaxation of carriers
    via emission of LO-phonons estimated to occur on a 200-fs time scale as in bulk
    GaAs.1 To corroborate this interpretation, the unknown LO-phonon emission times
    in the superlattices must be measured for the experimental conditions of the THz-emission
    experiments. In this paper, a combined investigation of the coherent and incoherent
    dynamics of optically excited charge carriers in a superlattice structure is presented.
    A comparison of the characteristic time constants provides clear evidence for
    the conservation of the phase of the intraband coherence on LO-phonon relaxation.

  text: In recent years the linear emission dynamics of microcavities containing an
    optical absorber has been a subject of intense research. For strong coupling between
    the cavity and the absorber, the spectrum of the coupled system shows two peaks
    and the linear dynamics of the coupled system is dominated by pronounced oscillations
    at the normal mode frequency.1 Yet, the uniqueness of the coupled absorber-cavity
    system cannot be concluded from its linear dynamics.
