text: The behavior of waveguide plasmon polaritons is studied employing ultrafast
coherent control like schemes for a gold lattice coupled to a photonic waveguide
for the structure. Different models to describe the third-harmonic generation
are presented and the resulting equations are solved numerically. The calculations
are compared to recent experimental data and show good agreement for the most
prominent features in the time-integrated third order intensity.

text: We present a joint theoretical study of the optical properties of GaAs and
AlAs bulk and heterostructures. Thereby, we compare the theoretical description
of optical excitation on several levels of theory. Results obtained from kp theory
are discussed along with data from ab initio calculations within the frameworks
of independent-particle (DFT), independent quasiparticle (GW), or Coulomb-correlated
quasiparticle (BSE) approximation.

text: "Excitonic spectra of weakly disordered semiconductor heterostructures are
simulated on the basis of a\r\none-dimensional tight-binding model. The influence
of the length scale of weak disorder in quantum wells on\r\nthe redshift of the
excitonic peak and its linewidth is studied. By calculating two-dimensional Fouriertransform\r\nspectra
we are able to determine the contribution of disorder to inhomogeneous and also
to homogeneous\r\nbroadenings separately. This disorder-induced dephasing is related
to a Fano-type coupling and leads\r\nto contributions to the homogeneous linewidth
that depends on energy within the inhomogeneously broadened\r\nline. The model
includes heavy- and light-hole excitons and yields smaller inhomogeneous broadening
for the\r\nlight-hole exciton if compared to the heavy-hole exciton, which agrees
qualitatively with the experiment."

text: We numerically investigate the behavior of Whispering Gallery Modes (WGMs)
in circularly shaped resonators like microdisks, with diameters in the range of
optical vacuum wavelengths. The microdisk is embedded in an uniaxial anisotropic
dielectric environment. By changing the optical anisotropy, one obtains spectral
tunability of the optical modes. The degree of tunability strongly depends on
the radial (azimuthal) mode order M (N). As the modes approach each other spectrally,
anticrossing is observed, leading to a rearrangement of the optical states.

text: The coherent state manipulation of single quantum systems is a fundamental
requirement for the implementation of quantum information processors. Exciton
qubits are of particular interest for coherent optoelectronic applications, in
particular due to their excellent coupling to photons. Until now, coherent manipulations
of exciton qubits in semiconductor quantum dots have been performed predominantly
by pulsed laser fields. Coherent control of the population of excitonic states
with a single laser pulse, observed by Rabi oscillations, has been demonstrated
by several groups using different techniques1,2,3. By using two laser pulses,
more general state control can be achieved4, and coupling of two excitons has
been reported5,6. Here, we present a conceptually new approach for implementing
the coherent control of an exciton two-level system (qubit) by means of a time-dependent
electric interaction. The new scheme makes use of an optical clock signal and
a synchronous electric gate signal, which controls the coherent manipulation.

text: GaAs-based semiconductor microdisks with high quality whispering gallery modes
(Q44000) have been fabricated.A layer of self-organized InAs quantumdots (QDs)
served as a light source to feed the optical modes at room temperature. In order
to achieve frequency tuning of the optical modes, the microdisk devices have been
immersed in 4 – cyano – 4´-pentylbiphenyl (5CB), a liquid crystal(LC) with a nematic
phase below the clearing temperature of TC≈34°C .We have studied the device performance
in the temperature rangeof T=20-50°C, in order to investigate the influence of
the nematic–isotropic phase transition on the optical modes. Moreover,we havea
pplied an AC electric field to the device,which leads in the nematic phase to
a reorientation of the anisotropic dielectric tensor of the liquid crystal.This
electrical anisotropy can be used to achieve electrical tunability of the optical
modes.Using the finite-difference time domain (FDTD) technique with an anisotropic
material model, we are able to describe the influence of the liquid crystal qualitatively.

text: "It is demonstrated that valence-band mixing in GaAs quantum wells tremendously
modifies electronic\r\ntransport. A coherent control scheme in which ultrafast
currents are optically injected into undoped GaAs\r\nquantum wells upon excitation
with femtosecond laser pulses is employed. An oscillatory dependence of\r\nthe
injection current amplitude and direction on the excitation photon energy is observed.
A microscopic\r\ntheoretical analysis shows that this current reversal is caused
by the coupling of the light- and heavy-hole\r\nbands and that the hole currents
dominate the overall current response. These surprising consequences of\r\nband
mixing illuminate fundamental physics as they are unique for experiments which
are able to monitor\r\nelectronic transport resulting from carriers with relatively
large momenta."

text: "The electromagnetic field in the vicinity of sharp edges needs a special
treatment in numeric calculation whenever accurate, fast converging results are
necessary. One of the fundamental works concerning field singularities has been
proposed in 1972 [1] and states that the electromagnetic energy density must be
integrable over any finite\r\ndomain, even if this domain contains singularities.
It is shown, that the magnetic field \x02H(\x03, ϕ) and electric field \x02E(\x03,
ϕ) are proportional to ∝ \x03(t−1) for \x03 → 0. The variable \x03 is the distance
to the edge and t has to fulfill the integrability condition and thus is restricted
to 0 < t < 1. This result is often used to reduce the error corresponding to the
singularity without increasing the numerical effort [2 - 5]. For this purpose,
a correction factor K is estimated by inserting the proportionality into the wave
equation. It is shown, that this method improves the accuracy of the result significantly,
however the order of convergence is often not studied. In [4] a method to modify
the material parameters in order to use analytic results to improve the numeric
calculation is presented. In this contribution we will - inspired by the scheme
given in [4] - develop a new method to estimate a correction factor for perfect
conducting materials (PEC) and demonstrate the improvement of the results compared
to the standard edge correction. Therefore analytic results (comparable to [1])
are consequently merged with the scheme in [4]. The main goal of this work is
the calculation of the second harmonic generation (SHG) in the wave response of
so-called metamaterials [6]. Frequently these structures\r\ncontain sharp metallic
edges with field singularities at the interfaces which have a strong impact on
the SHG signals. Thus, an accurate simulation of singularities is highly important.
However, the following approach can also be applied to many other setups, and
one of them is shown in the example below."

text: "Microdisks made from GaAs with embedded InAs quantum dots are immersed in
the liquid crystal 4-cyano-4’-pentylbiphenyl (5CB). The quantum dots serve as
emitters feeding the optical modes of the photonic cavity. By changing temperature,
the liquid crystal undergoes a phase transition from the isotropic to the nematic
state, which can be used\r\nas an effective tuning mechanism of the photonic modes
of the cavity. In the nematic state, the uniaxial electrical anisotropy of the
liquid crystal molecules can be exploited for orienting the material in an electric
field,\r\nthus externally controlling the birefringence of the material. Using
this effect, an electric field induced tuning of the modes is achieved. Numerical
simulations using the finite-differences time-domain (FDTD) technique\r\nemploying
an anisotropic dielectric medium allow to understand the alignment of the liquid
crystal molecules on the surface of the microdisk resonator."

text: We demonstrate a technique for the generation and detection of electron currents
at surfaces on a femtosecond time scale with a contact-free experimental setup
based on a combination of coherent control and photoemission spectroscopy. We
have applied this technique for electrons excited into image-potential states
on a Cu(100) surface that form a free-electron-like band in the direction parallel
to the surface. The photogeneration of currents is described by optical Bloch
equations for a multiband model. By incorporating field-induced interband and
intersubband transitions together with intraband accelerations into the model,
the observed phase dependence of the population and of the current can be reproduced.

text: Recently it has been shown experimentally that it is possible to coherently
control nano-optical excitations by using sophisticated shaped laser pulses. In
this work a similar technique is used to theoretically investigate a hybrid nanostructure
which consists of a metal aperture and a quantum wire. It is shown that one can
concentrate the optically excited electron density at an arbitrary position due
to wave packet dynamics by chosing particular frequency components and phases
of the chirped laser pulse. The optimization process is performed with a genetic
algorithm which is linked to a 3D-FDTD solver.

text: A one-dimensional semiconductor nanostructure is locally excited through a
metal aperture. It is shown that the electron density can be coherently localized
at desired spatial and temporal positions by using nontrivially shaped laser pulses.
To obtain the optimized laser field, Bloch equations for a tight-binding model
system are solved together with a genetic pulse-shaping algorithm. Full three-dimensional
finite-difference time-domain (FDTD) simulations of the Maxwell–Bloch equations
confirm the predicted coherent spatiotemporal control.

text: We have experimentally investigated injection currents generated by all-optical
excitation of GaAs/AlGaAs quantum wells excited with 130 fs optical pulses. The
currents have been detected via free-space THz experiments at room temperature.
Our experiments prove that Coulomb effects strongly influence injection currents.
This becomes most prominently visible when exciting light-hole exciton transitions.
At this photon energy we observe a pronounced phase shift of the current transients
which is due to oppositely oriented heavy-hole and light-hole type contributions.
We are currently developing a microscopic theory based on a 14×14 k.p model in
combination with the semiconductor Bloch equations to describe the observed features
quantitatively. The combined theoretical and experimental approach will allow
us to analyze the influence of the bandstructure and interaction effects on the
injection current amplitude and current dynamics.

microscopic THz theory. Moreover, the response of unexcited semiconductors to
extremely intense THz fields is investigated .The intersubband transitions of
optically excited quantum wells using linear THz spectroscopy is also studied.
The computed differential transmission shows a characteristic Fano-like line shape
of the intersubband resonance. The pure intersubband contribution is given by
a simple Lorentzian. Applying the microscopic theory, the Fano features of the
total response can be attributed to the phase-sensitive superposition of the intersubband
transitions and the ponderomotive contribution. These results are in excellent
agreement with recent experiments.

text: 'The recently developed two-dimensional Fourier-Transform-Spectroscopy (2DFTS)
in the optical regime has been established as an elegant experiment, which has
manifold of applications in the investigation of semiconductor nanostructures.
Here we focus on the real and imaginary part 2DFT spectra. As predicted recently,
using rephasing and non-rephasing modes, we are able to determine the homogeneous
and inhomogeneous broadenings of coupled excitonic resonances even for weak disorder
where photon-echo data are not useful. Computed real and imaginary parts of the
2DFTS for rephasing and non-rephasing modes are compared with experimental data
of a GaAs quantum well. It is demonstrated, that phase sensitive data for the
rephasing and non-rephasing modes are able to accurately provide the disorder
induced broadening in a complex coupled system for each transition separately. '

text: "A microscopic analysis of the emitted radiation of a semiconductor nanostructure
after excitation with an extremely intense ultrashort laser pulse is presented.
It is shown that the extreme nonlinear optical response is not sufficiently described
by pure interband transitions but one has to include intraband effects as well.\r\nNumerical
solutions of extended Bloch equations that include the coupled inter- and intraband
dynamics are presented. For large excitation intensities, the intraband effects
strongly modify the polarization dynamics and lead to a strong enhancement of
high-harmonic generation compared to pure interband dynamics."
