text: Coherent nonlinear optical μ-spectroscopy is a frequently used tool in modern
material science as it is sensitive to many different local observables, which
comprise, among others, crystal symmetry and vibrational properties. The richness
in information, however, may come with challenges in data interpretation, as one
has to disentangle the many different effects like multiple reflections, phase
jumps at interfaces, or the influence of the Guoy-phase. In order to facilitate
interpretation, the work presented here proposes an easy-to-use semi-analytical
modeling Ansatz, which bases upon known analytical solutions using Gaussian beams.
Specifically, we apply this Ansatz to compute nonlinear optical responses of (thin
film) optical materials. We try to conserve the meaning of intuitive parameters
like the Gouy-phase and the nonlinear coherent interaction length. In particular,
the concept of coherence length is extended, which is a must when using focal
beams. The model is subsequently applied to exemplary cases of second- and third-harmonic
generation. We observe a very good agreement with experimental data, and furthermore,
despite the constraints and limits of the analytical Ansatz, our model performs
similarly well as when using more rigorous simulations. However, it outperforms
the latter in terms of computational power, requiring more than three orders less
computational time and less performant computer systems.

text: 'An ultra-fast change of the absorption onset for zincblende gallium-nitride
(zb-GaN) (fundamental bandgap: 3.23 eV) is observed by investigating the imaginary
part of the dielectric function using time-dependent femtosecond pump–probe spectroscopic
ellipsometry between 2.9 and 3.7 eV. The 266 nm (4.66 eV) pump pulses induce a
large electron–hole pair concentration up to 4×1020cm−3, which shift the transition
energy between conduction and valence bands due to many-body effects up to ≈500 meV.
Here, the absorption onset increases due to band filling while the bandgap renormalization
at the same time decreases the bandgap. Additionally, the absorption of the pump-beam
creates a free-carrier profile within the 605 nm zb-GaN layer with high free-carrier
concentrations at the surface, and low concentrations at the interface to the
substrate. This leads to varying optical properties from the sample surface (high
transition energy) to substrate (low transition energy), which are taken into
account by grading analysis for an accurate description of the experimental data.
For this, a model describing the time- and position-dependent free-carrier concentration
is formulated by considering the relaxation, recombination, and diffusion of those
carriers. We provide a quantitative analysis of optical experimental data (ellipsometric
angles Ψ and Δ) as well as a plot for the time-dependent change of the imaginary
part of the dielectric function.'

text: ' A process sequence enabling the large-area fabrication of nanopillar-patterned
semiconductor templates for selective-area heteroepitaxy is developed. Herein,
the nanopillar tops surrounded by a SiNx mask film serve
as nanoscale growth areas. The molecular beam epitaxial growth of InAs on such
patterned GaAs[Formula: see text]A templates is investigated by means of electron
microscopy. It is found that defect-free nanoscale InAs islands grow selectively
on the nanopillar tops at a substrate temperature of 425 °C. High-angle annular
dark-field scanning transmission electron microscopy imaging reveals that for
a growth temperature of 400 °C, the InAs islands show a tendency to form wurtzite
phase arms extending along the lateral [Formula: see text] directions from the
central zinc blende region of the islands. This is ascribed to a temporary self-catalyzed
vapor–liquid–solid growth on [Formula: see text] B facets, which leads to a kinetically
induced preference for the nucleation of the wurtzite phase driven by the local,
instantaneous V/III ratio, and to a concomitant reduction of surface energy of
the nanoscale diameter arms. '

text: Recent analyses by polarization resolved second-harmonic (SH) microscopy have
demonstrated that ferroelectric (FE) domain walls (DWs) can possess non-Ising
wall characteristics and topological nature. These analyses rely on locally analyzing
the properties, directionality, and magnitude of the second-order nonlinear tensor.
However, when inspecting FE DWs with SH microscopy, a manifold of different effects
may contribute to the observed signal difference between domains and DWs, i.e.,
far-field interference, Čerenkov-type phase-matching (CSHG), and changes in the
aforementioned local nonlinear optical properties. They all might be present at
the same time and, therefore, require careful interpretation and separation. In
this work, we demonstrate how the particularly strong Čerenkov-type contrast can
selectively be blocked using dark- and bright-field SH microscopy. Based on this
approach, we show that other contrast mechanisms emerge that were previously overlayed
by CSHG but can now be readily selected through the appropriate experimental geometry.
Using the methods presented, we show that the strength of the CSHG contrast compared
to the other mechanisms is approximately 22 times higher. This work lays the foundation
for the in-depth analysis of FE DW topologies by SH microscopy.

text: Thin-film materials from μm thickness down to single-atomic-layered 2D materials
play a central role in many novel electronic and optical applications. Coherent,
nonlinear optical (NLO) μ-spectroscopy offers insight into the local thickness,
stacking order, symmetry, or electronic and vibrational properties. Thin films
and 2D materials are usually supported on multi-layered substrates leading to
(multi-)reflections, interference, or phase jumps at interfaces during μ-spectroscopy,
which all can make the interpretation of experiments particularly challenging.
The disentanglement of the influence parameters can be achieved via rigorous theoretical
analysis. In this work, we compare two self-developed modeling approaches, a semi-analytical
and a fully vectorial model, to experiments carried out in thin-film geometry
for two archetypal NLO processes, second-harmonic and third-harmonic generation.
In particular, we demonstrate that thin-film interference and phase matching do
heavily influence the signal strength. Furthermore, we work out key differences
between three and four photon processes, such as the role of the Gouy-phase shift
and the focal position. Last, we can show that a relatively simple semi-analytical
model, despite its limitations, is able to accurately describe experiments at
a significantly lower computational cost as compared to a full vectorial modeling.
This study lays the groundwork for performing quantitative NLO μ-spectroscopy
on thin films and 2D materials, as it identifies and quantifies the impact of
the corresponding sample and setup parameters on the NLO signal, in order to distinguish
them from genuine material properties.<

text: Second harmonic (SH) microscopy represents a powerful tool for the investigation
of crystalline systems, such as ferroelectrics and their domain walls (DWs). Under
the condition of normal dispersion, i.e., the refractive index at the SH wavelength
is larger as compared to the refractive index at the fundamental wavelength, n(2ω)>n(ω),
bulk crystals will generate no SH signal. Should the bulk, however, contain DWs,
an appreciable SH signal will still be detectable at the location of DWs stemming
from the Čerenkov mechanism. In this work, we demonstrate both how SH signals
are generated in bulk media and how the Čerenkov mechanism can be inhibited by
using anomalous dispersion, i.e., n(ω)Journal of Applied

text: Thin-film lithium niobate (TFLN) in the form of x- or z-cut lithium-niobate-on-insulator
has attracted considerable interest as a very promising and novel platform for
developing integrated optoelectronic (nano)devices and exploring fundamental research.
Here, we investigate the coherent interaction length lc of optical second-harmonic
generation (SHG) microscopy in such samples, that are purposely prepared into
a wedge shape, in order to elegantly tune the geometrical confinement from bulk
thicknesses down to approximately 50 nm. SHG microscopy is a very powerful and
non-invasive tool for the investigation of structural properties in the biological
and solid-state sciences, especially for visualizing and analyzing ferroelectric
domains and domain walls. However, unlike in bulk lithium niobate (LN), SHG microscopy
in TFLN is impacted by interfacial reflections and resonant enhancement, both
of which rely on film thickness and substrate material. In this paper, we show
that the dominant SHG contribution measured on TFLN in backreflection is the co-propagating
phase-matched SHG signal and not the counter-propagating SHG portion as is the
case for bulk LN samples. Moreover, lc depends on the incident pump laser wavelength
(sample dispersion) but also on the numerical aperture of the focussing objective
in use. These experimental findings on x- and z-cut TFLN are excellently backed
up by our advanced numerical simulations.

text: Plasmonic nanoantennas for visible and infrared radiation strongly improve
the interaction of light with the matter on the nanoscale due to their strong
near-field enhancement. In this study, we investigate a double-resonant plasmonic
nanoantenna, which makes use of plasmonic field enhancement, enhanced outcoupling
of second harmonic light, and resonant lattice effects. Using this design, we
demonstrate how the efficiency of second harmonic generation can be increased
significantly by fully embedding the nanoantennas into nonlinear dielectric material
ZnO, instead of placing them on the surface. Investigating two different processes,
we found that the best fabrication route is embedding the gold nanoantennas in
ZnO using an MBE overgrowth process where a thin ZnO layer was deposited on nanoantennas
fabricated on a ZnO substrate. In addition, second harmonic generation measurements
show that the embedding leads to an enhancement compared to the emission of nanoantennas
placed on the ZnO substrate surface. These promising results facilitate further
research to determine the influence of the periodicity of the nanoantenna arrangement
of the resulting SHG signal.

poled domains in x-cut single-crystalline thin-film lithium niobate with periodicities
as short as 600 nm. Shaped single-voltage poling pulses were applied to electrode
structures that were fabricated by a combination of electron-beam and direct-writing
laser lithography. Evidence of successful poling with good quality was obtained
through second-harmonic microscopy and piezoresponse force microscopy imaging.
For the sub-micrometer period structures, we observed patterns with a double periodicity
formed by domain interactions and features with sizes <200 nm.

text: Thin film lithium niobate has been of great interest recently, and an understanding
of periodically poled thin films is crucial for both fundamental physics and device
developments. Second-harmonic (SH) microscopy allows for the noninvasive visualization
and analysis of ferroelectric domain structures and walls. While the technique
is well understood in bulk lithium niobate, SH microscopy in thin films is largely
influenced by interfacial reflections and resonant enhancements, which depend
on film thicknesses and substrate materials. We present a comprehensive analysis
of SH microscopy in x-cut lithium niobate thin films, based on a full three-dimensional
focus calculation and accounting for interface reflections. We show that the dominant
signal in backreflection originates from a copropagating phase-matched process
observed through reflections, rather than direct detection of the counterpropagating
signal as in bulk samples. We simulate the SH signatures of domain structures
by a simple model of the domain wall as an extensionless transition from a −χ(2)
to a +χ(2) region. This allows us to explain the main observation of domain structures
in the thin-film geometry, and, in particular, we show that the SH signal from
thin poled films allows to unambiguously distinguish areas, which are completely
or only partly inverted in depth.
