text: We perform a comprehensive theoretical study of the structural and electronic
properties of potassium niobate (KNbO3) in the cubic, tetragonal, orthorhombic,
monoclinic, and rhombohedral phase, based on density-functional theory. The influence
of different parametrizations of the exchange-correlation functional on the investigated
properties is analyzed in detail, and the results are compared to available experimental
data. We argue that the PBEsol and AM05 generalized gradient approximations as
well as the RTPSS meta-generalized gradient approximation yield consistently accurate
structural data for both the external and internal degrees of freedom and are
overall superior to the local-density approximation or other conventional generalized
gradient approximations for the structural characterization of KNbO3. Band-structure
calculations using a HSE-type hybrid functional further indicate significant near
degeneracies of band-edge states in all phases which are expected to be relevant
for the optical response of the material.

text: The optical properties of pristine and titanium-doped LiNbO3 are modeled from
first principles. The dielectric functions are calculated within time-dependent
density-functional theory, and a model long-range contribution is employed for
the exchange-correlation kernel in order to account for the electron-hole binding.
Our study focuses on the influence of substitutional titanium atoms on lithium
sites. We show that an increasing titanium concentration enhances the values of
the refractive indices and the reflectivity.

text: 'The optical properties of congruent lithium niobate are analyzed from first
principles. The dielectric function of the material is calculated within time-dependent
density-functional theory. The effects of isolated intrinsic defects and defect
pairs, including the NbLi4+ antisite and the NbLi4+−NbNb4+ pair, commonly addressed
as a bound polaron and bipolaron, respectively, are discussed in detail. In addition,
we present further possible realizations of polaronic and bipolaronic systems.
The absorption feature around 1.64 eV, ascribed to small bound polarons [O. F.
Schirmer et al., J. Phys.: Condens. Matter 21, 123201 (2009)], is nicely reproduced
within these models. Among the investigated defects, we find that the presence
of bipolarons at bound interstitial-vacancy pairs NbV−VLi can best explain the
experimentally observed broad absorption band at 2.5 eV. Our results provide a
microscopic model for the observed optical spectra and suggest that, besides NbLi
antisites and Nb and Li vacancies, Nb interstitials are also formed in congruent
lithium-niobate samples.'

text: "Semiconductor quantum dots are promising sources for polarization-entangled
photons. As an alternative\r\nto the usual cascaded biexciton-exciton emission,
direct two-photon emission from the biexciton can be used.\r\nWith a high-quality
optical resonator tuned to half the biexciton energy, a large proportion of the
photons\r\ncan be steered into the two-photon emission channel. In this case the
degree of polarization entanglement is\r\ninherently insensitive to the exciton
fine-structure splitting. In the present work we analyze the biexciton emission\r\nwith
particular emphasis on the influence of coupling of the quantum-dot cavity system
to its environment.\r\nEspecially for a high-quality cavity, the coupling to the
surrounding semiconductormaterial can open up additional\r\nphonon-assisted decay
channels. Our analysis demonstrates that with the cavity tuned to half the biexciton
energy,\r\nthe potentially detrimental influence of the phonons on the polarization
entanglement is strongly suppressed—high\r\ndegrees of entanglement can still
be achieved. We further discuss spectral properties and statistics of the emitted\r\ntwin
photons."

text: The electronic band structures of hexagonal ZnO and cubic ZnS, ZnSe, and ZnTe
compounds are determined within hybrid-density-functional theory and quasiparticle
calculations. It is found that the band-edge energies calculated on the G0W0 (Zn
chalcogenides) or GW (ZnO) level of theory agree well with experiment, while fully
self-consistent QSGW calculations are required for the correct description of
the Zn 3d bands. The quasiparticle band structures are used to calculate the linear
response and second-harmonic-generation (SHG) spectra of the Zn–VI compounds.
Excitonic effects in the optical absorption are accounted for within the Bethe–Salpeter
approach. The calculated spectra are discussed in the context of previous experimental
data and present SHG measurements for ZnO.

text: We propose and implement a new concept for thermochromic plasmonic elements.
It is based on vanadium dioxide (VO2) nanocrystals located in the near field of
surface plasmon polaritons supported by an otherwise unstructured gold thin film.
When the VO2 undergoes the metal-insulator phase transition, the coupling conditions
for conversion of light into propagating surface plasmon polaritons change markedly.
In particular, we realize thermochromic plasmonic grating couplers with substantial
switching contrast as well as tunable plasmonic couplers in a Kretschmann configuration.
The use of VO2 nanocrystals permits highly repetitive switching and room temperature
operation. Simulations based on the actual dielectric function of our VO2 nanocrystals
agree well with the experiment.

text: Light is often characterized only by its classical properties, like intensity
or coherence. When looking at its quantum properties, described by photon correlations,
new information about the state of the matter generating the radiation can be
revealed. In particular the difference between independent and entangled emitters,
which is at the heart of quantum mechanics, can be made visible in the photon
statistics of the emitted light. The well-studied phenomenon of superradiance
occurs when quantum–mechanical correlations between the emitters are present.
Notwithstanding, superradiance was previously demonstrated only in terms of classical
light properties. Here, we provide the missing link between quantum correlations
of the active material and photon correlations in the emitted radiation. We use
the superradiance of quantum dots in a cavity-quantum electrodynamics laser to
show a direct connection between superradiant pulse emission and distinctive changes
in the photon correlation function. This directly demonstrates the importance
of quantum–mechanical correlations and their transfer between carriers and photons
in novel optoelectronic devices.

text: "Confocal Raman spectroscopy is applied to identify ferroelectric domain structure
sensitive\r\nphonon modes in potassium titanyl phosphate. Therefore, polarization-dependent
measurements in\r\nvarious scattering configurations have been performed to characterize
the fundamental Raman\r\nspectra of the material. The obtained spectra are discussed
qualitatively based on an internal mode\r\nassignment. In the main part of this
work, we have characterized z-cut periodically poled potassium\r\ntitanyl phosphate
in terms of polarity- and structure-sensitive phonon modes. Here, we find vibrations\r\nwhose
intensities are linked to the ferroelectric domain walls. We interpret this in
terms of\r\nchanges in the polarizability originating from strain induced by domain
boundaries and the inner\r\nfield distribution. Hence, a direct and 3D visualization
of ferroelectric domain structures becomes\r\npossible in potassium titanyl phosphate."

text: "We report the fabrication of periodically poled domain patterns in x-cut
lithium niobate thin-film.\r\nHere, thin films on insulator have drawn particular
attention due to their intrinsic waveguiding\r\nproperties offering high mode
confinement and smaller devices compared to in-diffused waveguides\r\nin bulk
material. In contrast to z-cut thin film lithium niobate, the x-cut geometry does
not\r\nrequire back electrodes for poling. Further, the x-cut geometry grants
direct access to the largest\r\nnonlinear and electro-optical tensor element,
which overall promises smaller devices. The domain\r\ninversion was realized via
electric field poling utilizing deposited aluminum top electrodes on a\r\nstack
of LN thin film/SiO2 layer/Bulk LN, which were patterned by optical lithography.
The periodic\r\ndomain inversion was verified by non-invasive confocal second
harmonic microscopy. Our\r\nresults show domain patterns in accordance to the
electrode mask layout. The second harmonic signatures\r\ncan be interpreted in
terms of spatially, overlapping domain filaments which start their\r\ngrowth on
the þz side."

text: Cubic gallium nitride (GaN) films are analyzed with highresolution X-ray diffraction
(HRXRD) and Raman spectroscopy. Several cubic GaN layers were grown on 3C-SiC
(001) substrate by radio-frequency plasma-assisted molecular beam epitaxy. The
layer thickness of the cubic GaN was varied between 75 and 505 nm. The HRXRD analysis
reveals a reduction of the full-width at half-maximum (FWHM) of omega scans for
growing layer thicknesses, which is caused by a partial compensation of defects.
The Raman characterization confirms well-formed c-GaN layers. A more detailed
examination of the longitudinal optical mode hints at a correlation of the FWHM
of the Raman mode with the dislocation density, which shows the possibility to
determine dislocation densities by Ramanspectroscopy on a micrometer scale, which
is not possible by HRXRD. Furthermore, this Raman analysis shows that normalized
Raman spectra present an alternative way to determine layer thicknesses of thin
GaN films.

text: "Congruent lithium niobate and lithium tantalate mixed crystals have been
grown over the complete\r\ncompositional range with the Czochralski method. The
structural and vibrational properties of the mixed\r\ncrystals are studied extensively
by x-ray diffraction measurements, Raman spectroscopy, and density functional\r\ntheory.
The measured lattice parameters and vibrational frequencies are in good agreement
with our theoretical\r\npredictions. The observed dependence of the Raman frequencies
on the crystal composition is discussed on the\r\nbasis of the calculated phonon
displacement patterns. The phononic contribution to the static dielectric tensor\r\nis
calculated by means of the generalized Lyddane-Sachs-Teller relation. Due to the
pronounced dependence of\r\nthe optical response on the Ta concentration, lithium
niobate tantalate mixed crystals represent a perfect model\r\nsystem to study
the properties of uniaxial mixed ferroelectric materials for application in integrated
optics."

text: We investigate the transient optical response in high-quality Cd0.88Zn0.12Te
crystals in the regime of slow light propagation on the lower exciton-polariton
branch. Femtosecond photoexcitation leads to very substantial transmission changes
in a ∼10-meV broad spectral range within the transparency window of the unexcited
semiconductor. These nonlinear optical signatures decay on picosecond time scales
governed by carrier thermalization and recombination. The temporal and spectral
dependence indicate the dynamical optical response as arising from excitation-induced
dephasing and perturbed free induction decay. Model simulations for the optical
response taking into account the actual exciton-polariton dispersion and excitation-induced
dephasing of a nonlinearly driven two-level system support this interpretation.
