text: The biphoton correlation time, a measure for the conditional uncertainty in
the temporal arrival of two photons from a photon pair source, is a key performance
identifier for many quantum spectroscopy applications, with shorter correlation
times typically yielding better performance. Furthermore, it provides fundamental
insight into the effects of dispersion on the biphoton state. Here, we show that
a characteristic dependence of the width of the temporal interferogram can be
exploited to obtain insights into the amount of second-order dispersion inside
the interferometer and to retrieve actual and Fourier-limited ultrashort biphoton
correlation times of around 100 fs. In the presented scheme, we simultaneously
measure spectral and temporal interferograms at the output of an SU(1,1) interferometer
based on an integrated broadband parametric down conversion source in a Ti:LiNbO3
waveguide.

text: We study the DC conductivity in potassium titanyl phosphate (KTiOPO4, KTP)
and its isomorphs KTiOAsO4 (KTA) and Rb1%K99%TiOPO4 (RKTP) and introduce a method
by which to reduce the overall ionic conductivity in KTP by a potassium nitrate
treatment. Furthermore, we create so-called gray tracking in KTP and investigate
the ionic conductivity in theses areas. A local unintended reduction of the ionic
conductivity is observed in the gray-tracked regions, which also induce additional
optical absorption in the material. We show that a thermal treatment in an oxygen-rich
atmosphere removes the gray tracking and brings the ionic conductivity as well
as the optical transmission back to the original level. These studies can help
to choose the best material and treatment for specific applications.

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 SU(1,1) interferometers are fruitful and promising tools
for spectral engineering and precise measurements with phase sensitivity below
the classical bound. Such interferometers have been successfully realized in bulk
and fiber-based configurations. However, rapidly developing integrated technologies
provide higher efficiencies, smaller footprints, and pave the way to quantum-enhanced
on-chip interferometry. In this work, we theoretically realised an integrated
architecture of the multimode SU(1,1) interferometer which can be applied to various
integrated platforms. The presented interferometer includes a polarization converter
between two photon sources and utilizes a continuous-wave (CW) pump. Based on
the potassium titanyl phosphate (KTP) platform, we show that this configuration
results in almost perfect destructive interference at the output and supersensitivity
regions below the classical limit. In addition, we discuss the fundamental difference
between single-mode and highly multimode SU(1,1) interferometers in the properties
of phase sensitivity and its limits. Finally, we explore how to improve the phase
sensitivity by filtering the output radiation and using different seeding states
in different modes with various detection strategies.

text: The characterisation of loss in optical waveguides is essential in
understanding the performance of these devices and their limitations. Whilst interferometric-based
methods generally provide the best results for low-loss waveguides, they are almost
exclusively used to provide characterization in cases where the waveguide is spatially
single-mode. Here, we introduce a Fabry-Pérot-based scheme to estimate the losses
of a nonlinear (birefringent or quasi-phase matched) waveguide at a wavelength
where it is multi-mode. The method involves measuring the generated second harmonic
power as the pump wavelength is scanned over the phase matching region. Furthermore,
it is shown that this method allows one to infer the losses of different second
harmonic spatial modes by scanning the pump field over the separated phase matching
spectra. By fitting the measured phase matching spectra from different titanium
indiffused lithium niobate waveguides to the model presented in this paper, it
is shown that one can estimate the second harmonic losses of a single spatial-mode,
at wavelengths where the waveguides are spatially multi-mode.
