  text: We present a combined experimental and numerical study of the far-field emission
    properties of optical travelling wave antennas made from low-loss dielectric materials.
    The antennas considered here are composed of two simple building blocks, a director
    and a reflector, deposited on a glass substrate. Colloidal quantum dots placed
    in the feed gap between the two elements serve as internal light source. The emission
    profile of the antenna is mainly formed by the director while the reflector suppresses
    backward emission. Systematic studies of the director dimensions as well as variation
    of antenna material show that the effective refractive index of the director primarily
    governs the far-field emission pattern. Below cut off, i.e., if the director’s
    effective refractive index is smaller than the refractive index of the substrate,
    the main lobe results from leaky wave emission along the director. In contrast,
    if the director supports a guided mode, the emission predominately originates
    from the end facet of the director.

  text: <jats:p>High harmonic generation (HHG) from solids shows great application
    prospects in compact short-wavelength light sources and as a tool for imaging
    the dynamics in crystals with subnanometer spatial and attosecond temporal resolution.
    However, the underlying collision dynamics behind solid HHG is still intensively
    debated and no direct mapping relationship between the collision dynamics with
    band structure has been built. Here, we show that the electron and its associated
    hole can be elastically scattered by neighboring atoms when their wavelength approaches
    the atomic size. We reveal that the elastic scattering of electron/hole from neighboring
    atoms can dramatically influence the electron recombination with its left-behind
    hole, which turns out to be the fundamental reason for the anisotropic interband
    HHG observed recently in bulk crystals. Our findings link the electron/hole backward
    scattering with Van Hove singularities and forward scattering with critical lines
    in the band structure and thus build a clear mapping between the band structure
    and the harmonic spectrum. Our work provides a unifying picture for several seemingly
    unrelated experimental observations and theoretical predictions, including the
    anisotropic harmonic emission in MgO, the atomic-like recollision mechanism of
    solid HHG, and the delocalization of HHG in ZnO. This strongly improved understanding
    will pave the way for controlling the solid-state HHG and visualizing the structure-dependent
    electron dynamics in solids.</jats:p>

  text: <jats:title>Abstract</jats:title><jats:p>Methylammonium lead iodide perovskite
    (MAPbI<jats:sub>3</jats:sub>) is renowned for an impressive power conversion efficiency
    rise and cost-effective fabrication for photovoltaics. In this work, we demonstrate
    that polycrystalline MAPbI<jats:sub>3</jats:sub>s undergo drastic changes in optical
    properties at moderate field strengths with an ultrafast response time, via transient
    Wannier Stark localization. The distinct band structure of this material - the
    large lattice periodicity, the narrow electronic energy bandwidths, and the coincidence
    of these two along the same high-symmetry direction – enables relatively weak
    fields to bring this material into the Wannier Stark regime. Its polycrystalline
    nature is not detrimental to the optical switching performance of the material,
    since the least dispersive direction of the band structure dominates the contribution
    to the optical response, which favors low-cost fabrication. Together with the
    outstanding photophysical properties of MAPbI<jats:sub>3</jats:sub>, this finding
    highlights the great potential of this material in ultrafast light modulation
    and novel photonic applications.</jats:p>

  text: Lithium niobate (LiNbO3), a material frequently used in optical applications,
    hosts different kinds of polarons that significantly affect many of its physical
    properties. In this study, a variety of electron polarons, namely free, bound,
    and bipolarons, are analyzed using first-principles calculations. We perform a
    full structural optimization based on density-functional theory for selected intrinsic
    defects with special attention to the role of symmetry-breaking distortions that
    lower the total energy. The cations hosting the various polarons relax to a different
    degree, with a larger relaxation corresponding to a larger gap between the defect
    level and the conduction-band edge. The projected density of states reveals that
    the polaron states are formerly empty Nb 4d states lowered into the band gap.
    Optical absorption spectra are derived within the independent-particle approximation,
    corrected by the GW approximation that yields a wider band gap and by including
    excitonic effects within the Bethe-Salpeter equation. Comparing the calculated
    spectra with the density of states, we find that the defect peak observed in the
    optical absorption stems from transitions between the defect level and a continuum
    of empty Nb 4d states. Signatures of polarons are further analyzed in the reflectivity
    and other experimentally measurable optical coefficients.

  text: We perform a theoretical analysis of the structural and electronic properties
    of sodium potassium niobate K1-xNaxNbO3 in the orthorhombic room-temperature phase,
    based on density-functional theory in combination with the supercell approach.
    Our results for x=0 and x=0.5 are in very good agreement with experimental measurements
    and establish that the lattice parameters decrease linearly with increasing Na
    contents, disproving earlier theoretical studies based on the virtual-crystal
    approximation that claimed a highly nonlinear behavior with a significant structural
    distortion and volume reduction in K0.5Na0.5NbO3 compared to both end members
    of the solid solution. Furthermore, we find that the electronic band gap varies
    very little between x=0 and x=0.5, reflecting the small changes in the lattice
    parameters.

  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: Employing the ultrafast control of electronic states of a semiconductor quantum
    dot in a cavity, we introduce an approach to achieve on-demand emission of single
    photons with almost perfect indistinguishability and photon pairs with near ideal
    entanglement. Our scheme is based on optical excitation off resonant to a cavity
    mode followed by ultrafast control of the electronic states using the time-dependent
    quantum-confined Stark effect, which then allows for cavity-resonant emission.
    Our theoretical analysis considers cavity-loss mechanisms, the Stark effect, and
    phonon-induced dephasing, allowing realistic predictions for finite temperatures.

  text: Density-functional theory within a Berry-phase formulation of the dynamical
    polarization is used to determine the second-order susceptibility χ(2) of lithium
    niobate (LiNbO3). Defect trapped polarons and bipolarons are found to strongly
    enhance the nonlinear susceptibility of the material, in particular if localized
    at NbV–VLi defect pairs. This is essentially a consequence of the polaronic excitation
    resulting in relaxation-induced gap states. The occupation of these levels leads
    to strongly enhanced χ(2) coefficients and allows for the spatial and transient
    modification of the second-harmonic generation of macroscopic samples.
