text: The authors present a detailed study of coherent tunneling oscillations of
an optically excited electronic wavepacket in a semiconductor double quantum-well
structure. The oscillation of the wavepacket between the two wells is traced by
time-resolved pump-probe spectroscopy as well as time-resolved degenerate four-wave
mixing. The experimental observations are compared with a simple theoretical model.
The motion of the wave packet is studied as a function of both an external electric
field and the lattice temperature. While the oscillation frequency shows the expected
dependence on electric field, it increases with temperature at fixed electric
field when perfectly delocalized electronic states exist at low temperature.

text: We report the study of optical dephazing of Wannier-Stark ladder excitations
in a semiconductor superlattice by means of transient degenerate four-wave mixing.
We observe pronounced modulations of the signal with a time period varying linearly
with the electric field. The time period is found to equal the temporal periodicity
of Bloch oscillations, in agreement with theory. In addition, we find that the
dephazing time decreases with increasing localization of the Wannier-Stark states,
which is attributed to carrier escape out of the lowest miniband.

text: Femtosecond nonlinear laser spectroscopy is applied to study the dynamics
of coherent optical excitations in semiconductors. In particular, excitonic excitations
in quantum wells and superlattice structures are considered. Two examples demonstrate
that four-wave mixing experiments with time-resolved detection of the nonlinear
signal are able to distinguish between quantum beats and polarization interference.v

text: Summary form only given. The numerical investigations are based on a microscopic
many-body theory which allows one to compute the linear and nonlinear optical
properties of semiconductor superlattices in the presence of homogeneous electric
fields applied in the growth direction. The THz-emission due to the field-driven
dynamics of photoexcited carriers is investigated for the combined action of static
and alternating fields. For a driving field it was shown within a simple model
that the equations governing the intraband dynamics in the field-driven superlattice
should be analogous to the ones describing the superconducting Josephson junction.
The transport properties in this regime can be described by the picture of multi-photon-assisted
tunneling between Wannier-Stark states.

text: Summary form only given. Partly non-degenerate four-wave mixing is able to
detect coherent coupling between excitonic resonances like e.g. light-hole and
heavy-hole excitons or between an exciton and its continuum states. We apply an
extension of this method, which we call selective coherent spectroscopy (SCS),
to symmetrically strained (GaIn)As/Ga(PAs) multiple quantum-wells. The samples
are excited simultaneously by a picosecond pulse with wavevector k/sub 1/ and
a 100 fs pulse with wavevector k/sub 2/. The central wavelength of the picosecond
pulse is scanned over the entire spectrum of the 100 fs pulse and the four-wave
mixing signal in the direction 2k/sub 2/-k/sub 1/ is detected at a fixed energy.
This scan provides an SCS spectrum.

text: Summary form only given. For a proper understanding of nonlinear optical experiments
in semiconductors even the low-density limit Coulomb-induced many body correlations
beyond the Hartree-Fock decoupling scheme need to be considered. In the coherent
X(3) limit these correlations manifest themselves in the contributions of bound
and unbound two-exciton states to the optical response. The understanding of nonlinear
excitonic effects in the Stark effect of semiconductors including carrier-correlations
is still of fundamental interest.

text: 'Recent experiments by Roskos et al. in ultrashort optical pulse excitation
of biased coupled quantum wells have shown remarkable generation of terahertz
electromagnetic radiation. Two different effects were identified: (i) an oscillatory
field of frequency corresponding to the separation between the coupled levels
in the quantum-well pair (~ 1.5 THz); and (ii) an “instantaneous” electromagnetic
field pulse that appears to follow the time evolution of the exciting laser pulse.
The oscillatory field is understood to be caused by the coherent oscillation of
optically created electrons from one well to the other.[1] The “instantaneous”
part we believe is caused by a new mechanism proposed in Ref. 2. The essence of
this “instantaneous” mechanism is that electron-hole pairs are created in a biased
semiconductor with a net polarization. The density of these pairs follows the
light field, as does the induced polarization, hence, generating an electromagnetic
source that follows the light pulse. Such mechanisms have been discussed before
for photon energies below the optical bandgap energy,[3] although they have so
far been difficult to observe. In our work, we have generalized and extended such
effects to photon energies above the handgap energy. In this paper we will discuss
both of these mechanisms as well as the fourwave-mixing (FWM) signal,[4] and show
how they can be understood within one unified formalism. We will also show that
the calculations agree well with the experimental results.'
