text: Potassium titanyl phosphate (KTP) is a nonlinear optical material
with applications in high-power frequency conversion or quasi-phase matching in
submicron period domain grids. A prerequisite for these applications is a precise
control and understanding of the poling mechanisms to enable the fabrication of
high-grade domain grids. In contrast to the widely used material lithium niobate,
the domain growth in KTP is less studied, because many standard methods, such
as selective etching or polarization microscopy, provides less insight or are
not applicable on non-polar surfaces, respectively. In this work, we present results
of confocal Raman-spectroscopy of the ferroelectric domain structure in KTP. This
analytical method allows for the visualization of domain grids of the non-polar
KTP y-face and therefore more insight into the domain-growth and -structure in
KTP, which can be used for improved domain fabrication.

text: Nonlinear and quantum optical devices based on periodically-poled thin film
lithium niobate (PP-TFLN) have gained considerable interest lately, due to their
significantly improved performance as compared to their bulk counterparts. Nevertheless,
performance parameters such as conversion efficiency, minimum pump power, and
spectral bandwidth strongly depend on the quality of the domain structure in these
PP-TFLN samples, e.g., their homogeneity and duty cycle, as well as on the overlap
and penetration depth of domains with the waveguide mode. Hence, in order to propose
improved fabrication protocols, a profound quality control of domain structures
is needed that allows quantifying and thoroughly analyzing these parameters. In
this paper, we propose to combine a set of nanometer-to-micrometer-scale imaging
techniques, i.e., piezoresponse force microscopy (PFM), second-harmonic generation
(SHG), and Raman spectroscopy (RS), to access the relevant and crucial sample
properties through cross-correlating these methods. Based on our findings, we
designate SHG to be the best-suited standard imaging technique for this purpose,
in particular when investigating the domain poling process in x-cut TFLNs. While
PFM is excellently recommended for near-surface high-resolution imaging, RS provides
thorough insights into stress and/or defect distributions, as associated with
these domain structures. In this context, our work here indicates unexpectedly
large signs for internal fields occurring in x-cut PP-TFLNs that are substantially
larger as compared to previous observations in bulk LN.

text: In the last two decades, variably doped strontium barium niobate (SBN) has
attracted a lot of scientific interest mainly due to its specific non-linear optical
response. Comparably, the parental compound, i.e., undoped SBN, appears to be
less studied so far. Here, two different cuts of single-crystalline nominally
pure strontium barium niobate in the composition Sr0.61Ba0.39Nb2O6 (SBN61) are
comprehensively studied and analyzed with regard to their photoconductive responses.
We present conductance measurements under systematically varied illumination conditions
along either the polar z-axis or perpendicular to it (x-cut). Apart from a pronounced
photoconductance (PC) already under daylight and a large effect upon super-bandgap
illumination in general, we observe (i) distinct spectral features when sweeping
the excitation wavelength over the sub-bandgap region as then discussed in the
context of deep and shallow trap states, (ii) extremely slow long-term relaxation
for both light-on and light-off transients in the range of hours and days, (iii)
a critical dependence of the photoresponse on the pre-illumination history of
the sample, and (iv) a current–voltage hysteresis depending on both the illumination
and the electrical-measurement conditions in a complex manner.

text: Exceptionally electron-rich, nearly trigonal-planar tricyanidometalate anions
[Fe(CN)3]7− and [Ru(CN)3]7− were stabilized in LiSr3[Fe(CN)3] and AE3.5[M(CN)3]
(AE=Sr, Ba; M=Fe, Ru). They are the first examples of group 8 elements with the
oxidation state of −IV. Microcrystalline powders were obtained by a solid-state
route, single crystals from alkali metal flux. While LiSr3[Fe(CN)3] crystallizes
in P63/m, the polar space group P63 with three-fold cell volume for AE3.5[M(CN)3]
is confirmed by second harmonic generation. X-ray diffraction, IR and Raman spectroscopy
reveal longer C−N distances (124–128 pm) and much lower stretching frequencies
(1484–1634 cm−1) than in classical cyanidometalates. Weak C−N bonds in combination
with strong M−C π-bonding is a scheme also known for carbonylmetalates. Instead
of the formal notation [Fe−IV(CN−)3]7−, quantum chemical calculations reveal non-innocent
intermediate-valent CN1.67− ligands and a closed-shell d10 configuration for Fe,
that is, Fe2−.

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: Orange-colored crystals of the oxoferrate tellurate K12+6xFe6Te4−xO27 [x=0.222(4)]
were synthesized in a potassium hydroxide hydroflux with a molar water–base ratio
n(H2O)/n(KOH) of 1.5 starting from Fe(NO3)3 ⋅ 9H2O, TeO2 and H2O2 at about 200 °C.
By using (NH4)2TeO4 instead of TeO2, a fine powder consisting of microcrystalline
spheres of K12+6xFe6Te4−xO27 was obtained. K12+6xFe6Te4−xO27 crystallizes in the
acentric cubic space group Iurn:x-wiley:09476539:media:chem202102464:chem202102464-math-0001
3d. [FeIIIO5] pyramids share their apical atoms in [Fe2O9] groups and two of their
edges with [TeVIO6] octahedra to form an open framework that consists of two loosely
connected, but not interpenetrating, chiral networks. The flexibility of the hinged
oxometalate network manifests in a piezoelectric response similar to that of LiNbO3.The
potassium cations are mobile in channels that run along the <111> directions and
cross in cavities acting as nodes. The ion conductivity of cold-pressed pellets
of ball-milled K12+6xFe6Te4−xO27 is 2.3×10^(−4) S ⋅ cm^(−1) at room temperature.
Magnetization measurements and neutron diffraction indicate antiferromagnetic
coupling in the [Fe2O9] groups.

text: Domain walls (DWs) in ferroelectric (FE) and multiferroic materials possess
an ever-growing potential as integrated functional elements, for instance in optoelectronic
nanodevices. Mandatory, however, is the profound knowledge of the local-scale
electronic and optical properties, especially at DWs that are still incompletely
characterized to date. Here, we quantify the refractive index of individual FE
DWs in periodically-poled LiNbO3 (PPLN) single crystals.
When applying polarization-sensitive optical coherence tomography (PS-OCT) at
1300 nm using circular light polarization, we are able to probe the relevant electro-optical
properties close to and at the DWs, including also their ordinary and extraordinary
contributions. When comparing to numerical calculations, we conclude that the
DW signals recorded for ordinary and extraordinary polarization stem from an increased
refractive index of at least Δn > 2·10−3 that originates
from a tiny region of < 30 nm in width. PS-OCT hence provides an extremely
valuable tool to decipher and quantify subtle changes of refractive index profiles
for both inorganic and biomedical nanomaterial systems.

text: Broadband coherent anti-Stokes Raman scattering (B-CARS) has emerged in recent
years as a promising chemosensitive high-speed imaging technique. B-CARS allows
for the detection of vibrational sample properties in analogy to spontaneous Raman
spectroscopy, but also makes electronic sample environments accessible due to
its resonant excitation mechanism. Nevertheless, this technique has only gained
interest in the biomedical field so far, whereas CARS investigations on solid-state
materials are rare and concentrate on layered, two-dimensional materials such
as graphene and hexagonal boron nitride . In this work, we discuss the specific
properties of this technique when applied to single-crystalline samples, with
respect to signal generation, phase matching, and selection rules in the model
systems lithium niobate and lithium tantalate. Via polarized B-CARS measurements
and subsequent phase retrieval, we validate the predicted selection rules, unequivocally
assign the phonons of the A1(TO), E(TO) and A1(LO) branches to the detected CARS
peaks, and address differences in spontaneous Raman spectroscopy concerning peak
frequencies and scattering efficiencies. We thus establish this technique for
future investigations of solid-state materials, specifically in the field of ferroelectric
single crystals.

text: Optically nonlinear Pb2B5O9X (X = Cl, Br) borate halides are an important
group of materials for second harmonic generation (SHG). Additionally, they also
possess excellent photocatalytic activity and stability in the process of dechlorination
of chlorophenols, which are typical persistent organic pollutants. It would be
of great interest to conduct in situ (photo‐) catalysis investigations during
the whole photocatalytic process by SHG when considering them as photocatalytic
materials. In order to get superior photocatalytic efficiency and maximum surface
information, small particles are highly desired. Here, a low‐cost and fast synthesis
route that allows growing microcrystalline optically nonlinear Pb2B5O9X
borate halides at large quantities is introduced. When applying the ionothermal
growth process at temperatures between 130 and 170 °C, microcrystallites with
an average size of about 1 µm precipitate with an orthorhombic hilgardite‐like
borate halide structure. Thorough examinations using powder X‐ray diffraction
and scanning electron microscopy, the Pb2B5O9X microcrystals are indicated to
be chemically pure and single‐phased. Besides, the Pb2B5O9X borate halides' SHG
efficiencies are confirmed using confocal SHG microscopy. The low‐temperature
synthesis route thus makes these borate halides a highly desirable material for
surface studies such as monitoring chemical reactions with picosecond time resolution
and in situ (photo‐) catalysis investigations.

text: High-fidelity periodic poling over long lengths is required for robust, quasi-phase-matched
second-harmonic generation using the fundamental, quasi-TE polarized waveguide
modes in a thin-film lithium niobate (TFLN) waveguide. Here, a shallow-etched
ridge waveguide is fabricated in x-cut magnesium oxide doped TFLN and is poled
accurately over 5 mm. The high fidelity of the poling is demonstrated over long
lengths using a non-destructive technique of confocal scanning second-harmonic
microscopy. We report a second-harmonic conversion efficiency of up to 939 %/W
(length-normalized conversion efficiency 3757 %/Wcm²), measured at telecommunications
wavelengths. The device demonstrates a narrow spectral linewidth (1 nm) and can
be tuned precisely with a tuning characteristic of 0.1 nm/°C, over at least 40
°C without measurable loss of efficiency.

text: Quasi-phase-matched grating structures in lithium niobate waveguides with
sub-micrometer periodicities will benefit the development of short-wavelength
nonlinear optical devices. Here, we report on the reproducible formation of periodically
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.

- lang: eng
text: Mach-Zehnder electro-optic modulators (EOM) based on thin-film lithium niobate
bonded to a silicon photonic waveguide circuit have been shown to achieve very
high modulation bandwidths. Open eye-diagram measurements made in the time domain
of beyond-small-signal modulation are used to support the modulation-sideband
measurements in showing that such EOM’s can support high-frequency modulations
well beyond 100 GHz.
