  text: <jats:p>The crystal family of potassium titanyl phosphate (KTiOPO4) is a promising
    material group for applications in quantum and nonlinear optics. The fabrication
    of low-loss optical waveguides, as well as high-grade periodically poled ferroelectric
    domain structures, requires a profound understanding of the material properties
    and crystal structure. In this regard, Raman spectroscopy offers the possibility
    to study and visualize domain structures, strain, defects, and the local stoichiometry,
    which are all factors impacting device performance. However, the accurate interpretation
    of Raman spectra and their changes with respect to extrinsic and intrinsic defects
    requires a thorough assignment of the Raman modes to their respective crystal
    features, which to date is only partly conducted based on phenomenological modelling.
    To address this issue, we calculated the phonon spectra of potassium titanyl phosphate
    and the related compounds rubidium titanyl phosphate (RbTiOPO4) and potassium
    titanyl arsenate (KTiOAsO4) based on density functional theory and compared them
    with experimental data. Overall, this allows us to assign various spectral features
    to eigenmodes of lattice substructures with improved detail compared to previous
    assignments. Nevertheless, the analysis also shows that not all features of the
    spectra can unambigiously be explained yet. A possible explanation might be that
    defects or long range fields not included in the modeling play a crucial rule
    for the resulting Raman spectrum. In conclusion, this work provides an improved
    foundation into the vibrational properties in the KTiOPO4 material family.</jats:p>

  text: Interference between single photons is key for many quantum optics experiments
    and applications in quantum technologies, such as quantum communication or computation.
    It is advantageous to operate the systems at telecommunication wavelengths and
    to integrate the setups for these applications in order to improve stability,
    compactness and scalability. A new promising material platform for integrated
    quantum optics is lithium niobate on insulator (LNOI). Here, we realise Hong-Ou-Mandel
    (HOM) interference between telecom photons from an engineered parametric down-conversion
    source in an LNOI directional coupler. The coupler has been designed and fabricated
    in house and provides close to perfect balanced beam splitting. We obtain a raw
    HOM visibility of (93.5 ± 0.7) %, limited mainly by the source performance and
    in good agreement with off-chip measurements. This lays the foundation for more
    sophisticated quantum experiments in LNOI.

  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>Lithium niobate
    is a promising platform for integrated quantum optics. In this platform, we aim
    to efficiently manipulate and detect quantum states by combining superconducting
    single photon detectors and modulators. The cryogenic operation of a superconducting
    single photon detector dictates the optimisation of the electro-optic modulators
    under the same operating conditions. To that end, we characterise a phase modulator,
    directional coupler, and polarisation converter at both ambient and cryogenic
    temperatures. The operation voltage <jats:inline-formula>\r\n                     <jats:tex-math><?CDATA

  text: Highly directive antennas with the ability of shaping radiation patterns in
    desired directions are essential for efficient on-chip optical communication with
    reduced cross talk. In this paper, we design and optimize three distinct broadband
    traveling-wave tantalum pentoxide antennas exhibiting highly directional characteristics.
    Our antennas contain a director and reflector deposited on a glass substrate,
    which are excited by a dipole emitter placed in the feed gap between the two elements.
    Full-wave simulations in conjunction with global optimization provide structures
    with an enhanced linear directivity as high as 119 radiating in the substrate.
    The high directivity is a result of the interplay between two dominant TE modes
    and the leaky modes present in the antenna director. Furthermore, these low-loss
    dielectric antennas exhibit a near-unity radiation efficiency at the operational
    wavelength of 780 nm and maintain a broad bandwidth. Our numerical results are
    in good agreement with experimental measurements from the optimized antennas fabricated
    using a two-step electron-beam lithography, revealing the highly directive nature
    of our structures. We envision that our antenna designs can be conveniently adapted
    to other dielectric materials and prove instrumental for inter-chip optical communications
    and other on-chip applications.

  text: We demonstrate theoretically and experimentally complex correlations in the
    photon numbers of two-mode quantum states using measurement-induced nonlinearity.
    For this, we combine the interference of coherent states and single photons with
    photon sub-traction.

  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: We demonstrate the integration of amorphous tungsten silicide superconducting
    nanowire single-photon detectors on titanium in-diffused lithium niobate waveguides.
    We show proof-of-principle detection of evanescently coupled photons of 1550 nm
    wavelength using bidirectional waveguide coupling for two orthogonal polarization
    directions. We investigate the internal detection efficiency as well as detector
    absorption using coupling-independent characterization measurements. Furthermore,
    we describe strategies to improve the yield and efficiency of these devices.

  text: <jats:p>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.</jats:p>
