text: "Broadband quantum light is a vital resource for quantum metrology
and spectroscopy applications such as quantum optical coherence tomography or
entangled two photon absorption. For entangled two photon absorption in particular,
very high photon flux combined with high time-frequency entanglement is crucial
for observing a signal. So far these conditions could be met by using high power
lasers driving degenerate, type 0 bulk-crystal spontaneous parametric down conversion
(SPDC) sources. This naturally limits the available wavelength ranges and precludes
deterministic splitting of the generated output photons. In this work we demonstrate
an integrated two-colour SPDC source utilising a group-velocity matched lithium
niobate waveguide, reaching both exceptional brightness 1.52⋅106pairssmWGHz
and large bandwidth (7.8 THz FWHM) while pumped with a few mW of continuous wave
(CW) laser light. By converting a narrow band pump to broadband pulses the created
photon pairs show correlation times of Δτ ≈ 120 fs
while maintaining the narrow bandwidth Δω\r\n
\ p\r\n ≪ 1 MHz of the CW pump light,
yielding strong time-frequency entanglement. Furthermore our process can be adapted
to a wide range of central wavelengths."

text: The latest applications in ultrafast quantum metrology require bright, broadband
bi-photon sources with one of the photons in the mid-infrared and the other in
the visible to near infrared. However, existing sources based on bulk crystals
are limited in brightness due to the short interaction length and only allow for
limited dispersion engineering. Here, we present an integrated PDC source based
on a Ti:LiNbO3 waveguide that generates broadband bi-photons with central wavelengths
at 860 nm and 2800 nm. Their spectral bandwidth exceeds 25 THz and is achieved
by simultaneous matching of the group velocities (GVs) and cancellation of GV
dispersion for the signal and idler field. We provide an intuitive understanding
of the process by studying our source’s behavior at different temperatures and
pump wavelengths, which agrees well with simulations.

text: Lightweight design by using low-density and load-adapted materials
can reduce the weight of vehicles and the emissions generated during operation.
However, the usage of different materials requires innovative joining technologies
with increased versatility. In this investigation, the focus is on describing
and characterising the failure behaviour of connections manufactured by an innovative
thermomechanical joining process with adaptable auxiliary joining elements in
single-lap tensile-shear tests. In order to analyse the failure development in
detail, the specimens are investigated using in-situ computed tomography (in-situ
CT). Here, the tensile-shear test is interrupted at points of interest and CT
scans are conducted under load. In addition, the interrupted in-situ testing procedure
is validated by comparing the loading behaviour with conventional continuous tensile-shear
tests. The results of the in-situ investigations of joints with varying material
combinations clearly describe the cause of failure, allowing conclusions towards
an improved joint design.

text: "Piezoelektrische Keramiken finden sowohl in Sensoren als auch in Aktoren
Anwendung. Bei Hochleistungs-Ultraschallanwendungen sind diese Komponenten erheblichen
elektrischen und mechanischen Belastungen ausgesetzt, was zum Auftreten nichtlinearer
Effekte führt. Um das nichtlineare Materialverhalten piezoelektrischer Keramiken
zu charakterisieren, kann eine statische mechanische Last aufgebracht werden,
die den mechanischen Arbeitspunkt verschiebt. Durch Variation dieser statischen
mechanischen Belastung kann das lineare Verhalten in jedem Betriebspunkt charakterisiert
werden, woraufhin die nichtlinearen Eigenschaften des Materials angenähert werden
können. Allerdings ist die Sicherstellung einer homogenen mechanischen Last anspruchsvoll.
Alternativ kann eine hydrostatische Belastung realisiert werden, indem die Probe
in einen Behälter gegeben wird, der mit unter Druck stehendem Fluid gefüllt ist.
Dadurch wird eine gleichmäßige Lastverteilung über die Oberfläche der Probe erreicht.\r\n\r\nIn
diesem Beitrag wird ein Versuchsaufbau zur Durchführung elektrischer Impedanzmessungen
an piezoelektrischen Keramiken in einem Druckbehälter vorgestellt. Die Probe wird
im Inneren des Druckbehälters elektrisch kontaktiert. Unter Verwendung von unter
Druck stehendem Argon wird auf diese Weise die Messung der elektrischen Impedanz
unter hydrostatischer Last von bis zu 200 bar ermöglicht. Anschließend wird ein
inverses Verfahren angewendet, um die Materialparameter in Abhängigkeit von der
aufgebrachten Last zu ermitteln."

text: The estimation of accurate piezoelectric material parameters is a fundamental
prerequisite for simulation-driven design of piezoelectric actuators and sensors.
Previous studies show that a full set of material parameters can be determined
in an inverse procedure using a single disc-shaped specimen with an electrode
structured for increased sensitivity with respect to all material parameters.
However, in the case of high-power actuator applications, ring-shaped piezoelectric
components are often employed, necessitating an adaptation of the previously developed
method. The alteration in geometry introduces some advantages. Accordingly, there
is no longer any requirement to modify the electrode structure in order to enhance
sensitivity. The method to estimate the material parameters presented here consists
of a total of three stages. An initial, approximate estimation of the material
parameters is determined using analytical approximations for the resonance frequencies
from the IEEE standard. These values are optimised in an inverse procedure that
employs analytic expressions for the electrical impedance of piezoelectric rings
as the forward model. Further refinement is achieved by using Finite Element (FE)
simulations as the forward model again in an inverse procedure. The method is
applied to electrical impedance measurement data, yielding material parameters
for hard piezoelectric rings. The result shows a good agreement between the simulation
and measurement results, indicating realistic material parameter values.
