  text: <jats:p>Uniaxial anisotropy in nonlinear birefringent crystals limits the
    efficiency of nonlinear optical interactions and breaks the spatial symmetry of
    light generated in the parametric down-conversion (PDC) process. Therefore, this
    effect is usually undesirable and must be compensated for. However, high gain
    may be used to overcome the destructive role of anisotropy in order to generate
    bright two-mode correlated twin-beams. In this work, we provide a rigorous theoretical
    description of the spatial properties of bright squeezed light in the presence
    of strong anisotropy. We investigate a single crystal and a system of two crystals
    with an air gap (corresponding to a nonlinear SU(1,1) interferometer) and demonstrate
    the generation of bright correlated twin-beams in such configurations at high
    gain due to anisotropy. We explore the mode structure of the generated light and
    show how anisotropy, together with crystal spacing, can be used for radiation
    shaping.</jats:p>

  text: We demonstrate an optical arbitrary waveform measurement (OAWM) system that
    exploits a bank of silicon photonic (SiP) frequency-tunable coupled-resonator
    optical waveguide (CROW) filters for gapless spectral slicing of broadband optical
    signals. The spectral slices are coherently detected using a frequency comb as
    a multi-wavelength local oscillator (LO) and stitched together by digital signal
    processing (DSP). For high-quality signal reconstruction, we have implemented
    a maximum-ratio combining (MRC) technique based on precise calibration of the
    complex-valued opto-electronic transfer functions of all detection paths. In a
    proof-of-concept experiment, we demonstrate the viability of the scheme by implementing
    a four-channel system that offers an overall detection bandwidth of 140 GHz. Exploiting
    a femtosecond laser with precisely known pulse shape for calibration along with
    dynamic amplitude and phase estimation, we reconstruct 100 GBd QPSK, 16QAM and
    64QAM optical data signals. The reconstructed signals show improved quality compared
    to that obtained with a single high-speed intradyne receiver, while the electronic
    bandwidth requirements of the individual coherent receivers are greatly reduced.

  text: <jats:p>The development of renewable energies and smart mobility has profoundly
    impacted the future of the distribution grid. An increasing bidirectional energy
    flow stresses the assets of the distribution grid, especially medium voltage switchgear.
    This calls for improved maintenance strategies to prevent critical failures. Predictive
    maintenance, a maintenance strategy relying on current condition data of assets,
    serves as a guideline. Novel sensors covering thermal, mechanical, and partial
    discharge aspects of switchgear, enable continuous condition monitoring of some
    of the most critical assets of the distribution grid. Combined with machine learning
    algorithms, the demands put on the distribution grid by the energy and mobility
    revolutions can be handled. In this paper, we review the current state-of-the-art
    of all aspects of condition monitoring for medium voltage switchgear. Furthermore,
    we present an approach to develop a predictive maintenance system based on novel
    sensors and machine learning. We show how the existing medium voltage grid infrastructure
    can adapt these new needs on an economic scale.</jats:p>

  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: <jats:p>Hybrid quantum information processing combines the advantages of discrete
    and continues variable protocols by realizing protocols consisting of photon counting
    and homodyne measurements. However, the mode structure of pulsed sources and the
    properties of the detection schemes often require the use of optical filters in
    order to combine both detection methods in a common experiment. This limits the
    efficiency and the overall achievable squeezing of the experiment. In our work,
    we use photon subtraction to implement the distillation of pulsed squeezed states
    originating from a genuinely spatially and temporally single-mode parametric down-conversion
    source in non-linear waveguides. Due to the distillation, we witness an improvement
    of 0.17 dB from an initial squeezing value of −1.648 ± 0.002 dB, while achieving
    a purity of 0.58, and confirm the non-Gaussianity of the distilled state via the
    higher-order cumulants. With this, we demonstrate the source’s suitability for
    scalable hybrid quantum network applications with pulsed quantum light.</jats:p>

  text: <jats:p>Semiconductor microcavities are frequently studied in the context
    of semiconductor lasers and in application-oriented fundamental research on topics
    such as linear and nonlinear polariton systems, polariton lasers, polariton pattern
    formation, and polaritonic Bose–Einstein condensates. A commonly used approach
    to describe theoretical properties includes a phenomenological single-mode equation
    that complements the equation for the nonlinear optical response (interband polarization)
    of the semiconductor. Here, we show how to replace the single-mode equation by
    a fully predictive transfer function method that, in contrast to the single-mode
    equation, accounts for propagation, retardation, and pulse-filtering effects of
    the incident light field traversing the distributed Bragg reflector (DBR) mirrors,
    without substantially increasing the numerical complexity of the solution. As
    examples, we use cavities containing GaAs quantum wells and transition-metal dichalcogenides
    (TMDs).</jats:p>

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

    of entanglement is the basis of quantum information and quantum communication
    processes. Entangled systems with a large number of photons are of great interest
    at present because they provide a platform for streaming technologies based on
    photonics. In this paper we present a device which operates with four-photons
    and based on the Hong–Ou–Mandel interference. The presented device allows to maximize
    the degree of spatial entanglement and generate the highly entangled four-dimensional
    Bell states. Furthermore, the use of the interferometer in different regimes leads
    to fast interference fringes in the coincidence probability with period of oscillations
    twice smaller than the pump wavelength. We have a good agreement between theoretical
    simulations and experimental results.</jats:p>"

  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.
