  text: <jats:p>Exciton polariton condensates are macroscopic coherent states in which
    topological excitations can be observed. In this work, we observe the excitation
    of the vortices and realize tuning the topological charge by manipulating the
    pumping configurations. Using a digital micromirror device, we constructed an
    annular pumping pattern where the inner and outer rings can be easily tuned. Both
    the number and the topological charge of the vortices can be changed by slightly
    tuning the inner ring position against the outer ring. The experimental results
    can be reproduced in theory by the Gross–Pitaevskii equation. Our work offers
    to generate and manipulate vortices in exciton polariton condensates using a straightforward
    optical method.</jats:p>

  text: <jats:p>Lithium niobate and lithium tantalate are among the most widespread
    materials for nonlinear, integrated photonics. Mixed crystals with arbitrary Nb–Ta
    ratios provide an additional degree of freedom to not only tune materials properties,
    such as the birefringence but also leverage the advantages of the singular compounds,
    for example, by combining the thermal stability of lithium tantalate with the
    larger nonlinear or piezoelectric constants of lithium niobate. Periodic poling
    allows to achieve phase-matching independent of waveguide geometry and is, therefore,
    one of the commonly used methods in integrated nonlinear optics. For mixed crystals,
    periodic poling has been challenging so far due to the lack of homogeneous, mono-domain
    crystals, which severely inhibit domain growth and nucleation. In this work, we
    investigate surface-near (&amp;lt;1μm depth) domain inversion on x-cut lithium
    niobate tantalate mixed crystals via electric field poling and lithographically
    structured electrodes. We find that naturally occurring head-to-head or tail-to-tail
    domain walls in the as-grown crystal inhibit domain inversion at a larger scale.
    However, periodic poling is possible if the gap size between the poling electrodes
    is of the same order of magnitude or smaller than the average size of naturally
    occurring domains. This work provides the basis for the nonlinear optical application
    of lithium niobate tantalate mixed crystals.</jats:p>

  text: '<jats:p>Ferroelectric domain wall conductivity (DWC) is an intriguing and
    promising functional property that can be elegantly controlled and steered through
    a variety of external stimuli such as electric and mechanical fields. Optical-field
    control, as a noninvasive and flexible tool, has rarely been applied so far, but
    it significantly expands the possibility for both tuning and probing DWC. On the
    one hand, as known from second-harmonic or Raman micro-spectroscopy, the optical
    approach provides information on DW distribution and inclination, while simultaneously
    probing the DW vibrational modes; on the other hand, photons might be applied
    to directly generate charge carriers, thereby acting as a functional and spectrally
    tunable probe to deduce the local absorption properties and bandgaps of conductive
    DWs. Here, we report on investigating the photo-induced DWC (PI-DWC) of three
    lithium niobate crystals, containing a very different number of DWs, namely: (A)
    none, (B) one, and (C) many conductive DWs. All three samples are inspected for
    their current–voltage behavior in darkness and for different illumination wavelengths
    swept from 500 nm down to 310 nm. All samples show their maximum PI-DWC at 310 nm;
    moreover, sample (C) reaches PI-DWCs of several microampere. Interestingly, a
    noticeable PI-DWC is also observed for sub-bandgap illumination, hinting toward
    the existence and decisive role of electronic in-gap states that contribute to
    the electronic charge transport along DWs. Finally, complementary conductive atomic
    force microscopy investigations under illumination proved that the PI-DWC indeed
    is confined to the DW area and does not originate from photo-induced bulk conductivity.</jats:p>'

  text: The achievement of a flat metasurface has realized extraordinary control over
    light–matter interaction at the nanoscale, enabling widespread use in imaging,
    holography, and biophotonics. However, three-dimensional metasurfaces with the
    potential to provide additional light–matter manipulation flexibility attract
    only little interest. Here, we demonstrate a three-dimensional metasurface scheme
    capable of providing dual phase control through out-of-plane plasmonic resonance
    of L-shape antennas. Under circularly polarized excitation at a specific wavelength,
    the L-shape antennas with rotating orientation angle act as spatially variant
    three-dimensional tilted dipoles and are able to generate desire phase delay for
    different polarization components. Generalized Snell's law is achieved for both
    in-plane and out-of-plane dipole components through arranging such L-shape antennas
    into arrays. These three-dimensional metasurfaces suggest a route for wavefront
    modulation and a variety of nanophotonic applications.

  text: Optical geometric phase encoded by in-plane spatial orientation of microstructures
    has promoted the rapid development of numerous functional meta-devices. However,
    pushing the concept of the geometric phase toward the acoustic community still
    faces challenges. In this work, we utilize two acoustic nonlocal metagratings
    that could support a direct conversion between an acoustic plane wave and a designated
    vortex mode to obtain the acoustic geometric phase, in which an orbital angular
    momentum conversion process plays a vital role. In addition, we realize the acoustic
    geometric phases of different orders by merely varying the orientation angle of
    the acoustic nonlocal metagratings. Intriguingly, according to our developed theory,
    we reveal that the reflective acoustic geometric phase, which is twice the transmissive
    one, can be readily realized by transferring the transmitted configuration to
    a reflected one. Both the theoretical study and experimental measurements verify
    the announced transmissive and reflective acoustic geometric phases. Moreover,
    the reconfigurability and continuous phase modulation that covers the 2π range
    shown by the acoustic geometric phases provide us with the alternatives in advanced
    acoustic wavefront control.

  text: <jats:p> Recently, microcavities with anisotropic materials were shown to
    be able to create bands with non-zero local Berry curvature. The anisotropic refractive
    index of the cavity layer is believed to be critical in opening an energy gap
    at the tilted Dirac points. In this work, we show that the anticrossing between
    a cavity mode and a Bragg mode can also be realized within an empty microcavity
    without any birefringent materials in the cavity layer. Nondispersive bands are
    observed within the energy gap due to the particular refractive index distribution
    of the sample. The intrinsic TE-TM splitting and XY splitting of DBR mirrors induce
    the squeezing of the cavity modes in momentum space, so that the nondispersive
    bands are tilted and spin-dependent. Our results pave the way to investigate interesting
    physical phenomena of photonic modes close to or in the nondispersive bands without
    anisotropic cavity layers. </jats:p>

  text: Spontaneous Raman spectroscopy (SR) is a versatile method for analysis and
    visualization of ferroelectric crystal structures, including domain walls. Nevertheless,
    the necessary acquisition time makes SR impractical for in situ analysis and large
    scale imaging. In this work, we introduce broadband coherent anti-Stokes Raman
    spectroscopy (B-CARS) as a high-speed alternative to conventional Raman techniques
    and demonstrate its benefits for ferroelectric domain wall analysis. Using the
    example of poled lithium niobate, we compare the spectral output of both techniques
    in terms of domain wall signatures and imaging capabilities. We extract the Raman-like
    resonant part of the coherent anti-Stokes signal via a Kramers–Kronig-based phase
    retrieval algorithm and compare the raw and phase-retrieved signals to SR characteristics.
    Finally, we propose a mechanism for the observed domain wall signal strength that
    resembles a Čerenkov-like behavior, in close analogy to domain wall signatures
    obtained by second-harmonic generation imaging. We, thus, lay here the foundations
    for future investigations on other poled ferroelectric crystals using B-CARS.

  text: In our work, we have engineered low capacitance single quantum dot photodiodes
    as sensor devices for the optoelectronic sampling of ultrafast electric signals.
    By the Stark effect, a time-dependent electric signal is converted into a time-dependent
    shift of the transition energy. This shift is measured accurately by resonant
    ps laser spectroscopy with photocurrent detection. In our experiments, we sample
    the laser synchronous output pulse of an ultrafast CMOS circuit with high resolution.
    With our quantum dot sensor device, we were able to sample transients below 20
    ps with a voltage resolution in the mV-range.

  text: <jats:p>GaAs quantum dots (QDs) have recently emerged as state-of-the-art
    semiconductor sources of polarization-entangled photon pairs, however, without
    site-control capability. In this work, we present a systematic study of epitaxially
    grown GaAs/AlxGa1-xAs site-controlled pyramidal QDs possessing unrivaled excitonic
    uniformity in comparison to their InGaAs counterparts or GaAs QDs fabricated by
    other techniques. We have experimentally and systematically investigated the binding
    energy of biexcitons, highlighting the importance of the uniformity of all excitonic
    lines, rather than concentrating solely on the uniformity of the neutral exciton
    as a typical figure of merit, as it is normally done in the literature. We present
    optical signatures of GaAs QDs within a range of ∼250 meV with a remarkable uniformity
    within each individual sample, the ability to excite the biexciton state resonantly,
    and a systematic study of the fine-structure splitting (FSS) values—features important
    for polarization entangled photon emission. While, in general, we observe relatively
    large FSS distribution and associated non-uniformities, we discuss several strategies
    to suppress the average FSS values to &amp;lt;15 μeV.</jats:p>

  text: <jats:p>Planar nanostructures allow near-ideal extraction of emission from
    a quantum emitter embedded within, thereby realizing deterministic single-photon
    sources. Such a source can be transformed into M single-photon sources by implementing
    active temporal-to-spatial mode demultiplexing. We report on the realization of
    such a demultiplexed source based on a quantum dot embedded in a nanophotonic
    waveguide. Efficient outcoupling (&amp;gt;60%) from the waveguide into a single
    mode optical fiber is obtained with high-efficiency grating couplers. As a proof-of-concept,
    active demultiplexing into M = 4 spatial channels is demonstrated by the use of
    electro-optic modulators with an end-to-end efficiency of &amp;gt;81% into single-mode
    fibers. Overall, we demonstrate four-photon coincidence rates of &amp;gt;1 Hz
    even under nonresonant excitation of the quantum dot. The main limitation of the
    current source is the residual population of other exciton transitions, which
    corresponds to a finite preparation efficiency of the desired transition. We quantitatively
    extract a preparation efficiency of 15% using the second-order correlation function
    measurements. The experiment highlights the applicability of planar nanostructures
    as efficient multiphoton sources through temporal-to-spatial demultiplexing and
    lays out a clear path way of how to scale up toward demonstrating quantum advantages
    with the quantum dot sources.</jats:p>

  text: "We report the fabrication of periodically poled domain patterns in x-cut
    lithium niobate thin-film.\r\nHere, thin films on insulator have drawn particular
    attention due to their intrinsic waveguiding\r\nproperties offering high mode
    confinement and smaller devices compared to in-diffused waveguides\r\nin bulk
    material. In contrast to z-cut thin film lithium niobate, the x-cut geometry does
    not\r\nrequire back electrodes for poling. Further, the x-cut geometry grants
    direct access to the largest\r\nnonlinear and electro-optical tensor element,
    which overall promises smaller devices. The domain\r\ninversion was realized via
    electric field poling utilizing deposited aluminum top electrodes on a\r\nstack
    of LN thin film/SiO2 layer/Bulk LN, which were patterned by optical lithography.
    The periodic\r\ndomain inversion was verified by non-invasive confocal second
    harmonic microscopy. Our\r\nresults show domain patterns in accordance to the
    electrode mask layout. The second harmonic signatures\r\ncan be interpreted in
    terms of spatially, overlapping domain filaments which start their\r\ngrowth on
    the þz side."
