text: "The strong influence of exciton/exciton interaction on the nonlinear optical
response of the 2D exciton in GaAs quantum wells has been demonstrated in several
recent experimental studies. The theoretical model for the microscopic coupling
mechanism is still the subject of controversy, however. In ref. [1], we have presented
a model including a density dependent coupling between opposite spin excitons
which assumes that the interaction results in a renormalization of the matrix
elements, dephasing rates and energies of the transition from the single-exciton
state to the two-exciton state with respect to the corresponding quantities for
the single exciton transitions. In contrast, Wang et al. claim that all experimental
observations are explained by a density induced dephasing rate and that biexciton
states play no role [2]. Here we present a new 3-pulse degenerate-four-wave-mixing
(DFWM) configuration which is able to differentiate between pure local field effects
and biexcitonic contributions to the time-integrated signal. Experiments were
performed on an almost homogeneously broadened GaAs/Al0.3Ga0.7As single QW (well
width 20 nm, photoluminescence line 0.3 meV, homogenous linewidth 0.15 meV) in
the backward reflection geometry. The sample was cooled to 10 K and excited by
a sequence of three pulses (1.1 ps duration) with equal intensity, wave vectors
\U0001D458→1,\U0001D458→2,\U0001D458→3\r\n and delays τ12 and τ13 between the
second and first and the third and first pulse, respectively. The signal was monitored
in the direction \U0001D458→\U0001D460=\U0001D458→1+\U0001D458→2−\U0001D458→3\r\n
which provides no signal for the chosen pulse length if local field and renormalization
effects are negligible. The peak intensity of the time-integrated DFWM signal
has been calculated by solving the optical Bloch for a system of two non-interacting
two-level systems (2LS) with opposite circular polarization selection rules (local
field effect) and for the renormalized four-level system (4LS) depicted in Fig.
1 which assumes the formation of biexcitons between excitons with opposite spins.
The signal strength is proportional to the strength of the local field in the
case of the 2LS and to the renormalization for the 4LS. The peak signal intensities
expected for pure local field and pure biexction contributions are summarized
in the second and third column of Table 1 for eight experimental configurations
applying different linear and circularly polarized pulses. The values are normalized
to the signal strength predicted for three parallel linearly polarized pulses.
Close inspection of the data reveals remarkable differences of the peak amplitude
with polarization geometry for the two coupling models."

text: Several recent experimental and theoretical studies have demonstrated the
importance of exciton/exciton coupling due to Coulomb interactions for the nonlinear
optical response of the 2D exciton in GaAs quantum wells (QWs).1,2 These results
imply that multilevel models are required in order to provide a theoretically
appropriate description of the nonlinear behavior. Previous application of a renormalized
9-level system has proven successful in describing the third-order response of
hh-excitons in GaAs quantum wells.2 We present a comprehensive experimental and
theoretical investigation of the polarization selection rules for degenerate-
four-wave-mixing (DFWM) and quantum beating of hh and lh transitions in a GaAs
QW. Depending on the polarization and temporal sequence of the three pulses simultaneous
excitation of the hh and lh transitions generates either quantum beats (QB), no
modulation of the signal, or a superposition of QB and polarization interference
(PI) effects as proved by spectrally resolved (SR)-DFWM.

text: Although the importance of exciton/exciton interactions for the nonlinear
optical response of GaAs quantum wells (QW) is well established by many experimental
observations, the role of biexciton states in these processes is still an open
question, even at low excitation densities. Evidence for the formation of biexcitons
has been independently derived from pump-probe studies [1], from the density dependence
of the photoluminescence (PL) line shape [2] and from signal modulations observed
in degenerate-four-wave-mixing (DFWM) with incoherent light pulses [3]. Here,
we report on time-resolved DFWM with parallel (PP) and cross-polarized (CP) pulses.
Depending on the polarization geometry, the signals reveal strong quantum beats
which correspond to the splitting between either the heavy hole (hh) and light
hole (lh) exciton or the hh exciton and the biexciton.

text: We have performed sub-picosecond four-wave mixing experiments on a series
of symmetrically strained (GaIn)As/Ga(AsP) multiple quantum wells. We show that
these measurements allow a precise determination of exciton binding energies.
One of the advantages of this quantum beat method as compared to linear optical
methods is that a determination of the exciton binding energy is possible even
in the presence of considerable inhomogeneous broadening. In addition, the dependence
of the exciton binding energy on the strain in the (GaIn)As quantum well layers
suggests that the reduced electron-hole effective mass is not influenced by the
increase in strain.

text: In the absence of scattering mechanisms, a crystal electron subjected to a
homogeneous electric field undergoes a periodic motion in both momentum and real
space. This oscillatory motion is known as Bloch oscillations (BOs) and has recently
been detected in transient four-wave mixing (FWM) and Tera-Hertz emission experiments
on semiconductor superlattices. It is generally assumed that the minimum field
required for the observation of BOs is controlled by the rate of scattering in
the material. However, an experimental verification of this point is still lacking.

text: The strong nonlinear optical response of the 2D exciton in GaAs quantum wells
at relatively low excitation densities has been observed in many experimental
studies in accordance with theoretical predictions. In principle, exciton/exciton
interaction results in a renormalization of the transition matrix elements, dephasing
rates and frequencies of the excitonic states. Wang et al.1 claimed that all experimental
results can be explained by a density- induced enhanced dephasing rate. In a previous
paper,2 we have suggested a density dependent coupling between opposite spin excitons,
which involves all three renormalization phenomena.

text: A proper description of subpicosecond four-wave-mixing (FWM) experiments for
excitonic transitions in semiconductor heterostructures must consider the fact
that the spectrally broad laser pulses excite not only the 1s bound exciton state
but also energetically higher bound exciton states and the lower-lying part of
the unbound continuum states. In this paper, we report results of transient and
time-resolved FWM-experiments in which such ’excitonic wave packets’ play a crucial
role. In addition, a theoretical treatment of the problem based on the solution
of the semiconductor Bloch is presented. We show that the time-dependent nonlinear
response is determined by an interplay between inhomogeneous broadening and Coulomb
interaction.

text: We present subpicosecond time-resolved four-wave-mixing studies on GaAs/AlAs
short-period superlattices having different miniband widths. Photon echoes are
observed as a consequence of the inhomogeneous broadening of the excitonic resonance.
In addition, the photon-echo signal exhibits periodic modulations as a function
of the time delay between the excitation laser pulses. Free excitons and excitons
bound to neutral acceptors are identified as the underlying three-level system
leading to the observed photon-echo quantum beats. From the beat period we can
directly infer the dissociation energy of the bound exciton. In accordance with
theory, we find that the dissociation energy decreases with increasing miniband
width, i.e., when the excitons become less confined. In addition, we find that
the dephasing rate of bound excitons is about one order of magnitude less than
that of free excitons and is mainly determined by energy relaxation.

text: Femtosecond nonlinear laser spectroscopy is applied to study the dynamics
of coherent optical excitations in semiconductors. In particular, beat phenomena
of excitonic excitations in quantum wells and superlattice structures will be
considered. We will demonstrate that four wave mixing experiments with time resolved
detection of the nonlinear signal are able to distinguish between quantum beats
and polarization interference. In addition, we report for a GaAs/AlAs superlattice
the observation of quantum beats in the photon echo signal. The occurence of these
beats is attributed to the simultaneous excitation of bound and localized excitons.

text: We report on the coherent dynamics of excitonic wave packets observed in transient
four-wave mixing experiments on strained InGaAs/GaAs quantum-well structures.
The excitonic noneigenstates are created by using laser pulses shorter than the
electron round trip time within the exciton orbital. A characteristic temporal
modulation of the diffracted signal is observed, which resembles the coherent
dynamics of an electron wave packet in a hydrogen atom expected for the case of
a simultaneous excitation of all bound and the lowest continuum states.

text: In degenerate four-wave-mixing (DFWM) experiments the polarization of the
incident laser pulses can have a strong influence on the measured signal. For
GaAs quantum wells a number of DFWM experiments were performed by using either
parallel or perpendicular polarization of the incident laser pulses. Experimentally,
it turned out that some characteristic features of the signal differ appreciably
for the two configurations. In particular, different dephasing times, phase shifts
of the quantum beats, different time-resolved behavior (echoes versus free-induction
decay), and intensity dependence of the measured signal have been reported

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.

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

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.'
