  text: <jats:title>Abstract</jats:title><jats:p>Polarons influence decisively the
    performance of lithium niobate for optical applications. In this work, the formation
    of (defect) bound polarons in lithium niobate is studied by ab initio molecular
    dynamics. The calculations show a broad scatter of polaron formation times. Rising
    temperature increases the share of trajectories with long formation times, which
    leads to an overall increase of the average formation time with temperature. However,
    even at elevated temperatures, the average formation time does not exceed the
    value of 100 femtoseconds, i.e., a value close to the time measured for free,
    i.e., self-trapped polarons. Analyzing individual trajectories, it is found that
    the time required for the structural relaxation of the polarons depends sensitively
    on the excitation of the lithium niobate high-frequency phonon modes and their
    phase relation.</jats:p>

  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: Online solvers for a series of standard 1-D or 2-D problems in integrated
    optics will be discussed. Implemented on the basis of HTML/JavaScript/SVG with
    core routines compiled from well tested C++-sources, the quasi-analytical algorithms
    require a computational load that can be handled easily even by current mobile
    devices. So far the series covers the 1-D guided modes of dielectric multilayer
    slab waveguides and the oblique plane wave reflection from these, the modes of
    rectangular channel waveguides (in an approximation of effective indices), bend
    modes of curved multilayer slabs, whispering-gallery resonances (“Quasi-Normal-Modes”)
    supported by circular dielectric cavities, the hybrid modes of circular multi-step-index
    optical fibers, bound and leaky modes of 1-D complex multilayers, including plasmonic
    surface modes, and, with restrictions, quite general rectangular scattering problems
    in 2-D.

  text: Many-body perturbation theory based on density-functional theory calculations
    is used to determine the quasiparticle band structures and the dielectric functions
    of the isomorphic ferroelectrics rubidium titanyl phosphate (RbTiOPO4) and potassium
    titanyl arsenide (KTiOAsO4). Self-energy corrections of more than 2 eV are found
    to widen the transport band gaps of both materials considerably to 5.3 and 5.2
    eV, respectively. At the same time, both materials are characterized by strong
    exciton binding energies of 1.4 and 1.5 eV, respectively. The solution of the
    Bethe-Salpeter equation based on the quasiparticle energies results in onsets
    of the optical absorption within the range of the measured data.

  text: Inspired by plant grafting, grafted vortex beams can be formed through grafting
    two or more helical phase profiles of optical vortex beams. Recently, grafted
    perfect vortex beams (GPVBs) have attracted much attention due to their unique
    optical properties and potential applications. However, the current method to
    generate and manipulate GPVBs requires a complex and bulky optical system, hindering
    further investigation and limiting its practical applications. Here, a compact
    metasurface approach for generating and manipulating GPVBs in multiple channels
    is proposed and demonstrated, which eliminates the need for such a complex optical
    setup. A single metasurface is utilized to realize various superpositions of GPVBs
    with different combinations of topological charges in four channels, leading to
    asymmetric singularity distributions. The positions of singularities in the superimposed
    beam can be further modulated by introducing an initial phase difference in the
    metasurface design. The work demonstrates a compact metasurface platform that
    performs a sophisticated optical task that is very challenging with conventional
    optics, opening opportunities for the investigation and applications of GPVBs
    in a wide range of emerging application areas, such as singular optics and quantum
    science.

  text: Subwavelength dielectric resonators assembled into metasurfaces have become
    a versatile tool for miniaturizing optical components approaching the nanoscale.
    An important class of metasurface functionalities is associated with asymmetry
    in both the generation and transmission of light with respect to reversals of
    the positions of emitters and receivers. The nonlinear light–matter interaction
    in metasurfaces offers a promising pathway towards miniaturization of the asymmetric
    control of light. Here we demonstrate asymmetric parametric generation of light
    in nonlinear metasurfaces. We assemble dissimilar nonlinear dielectric resonators
    into translucent metasurfaces that produce images in the visible spectral range
    on being illuminated by infrared radiation. By design, the metasurfaces produce
    different and completely independent images for the reversed direction of illumination,
    that is, when the positions of the infrared emitter and the visible light receiver
    are exchanged. Nonlinearity-enabled asymmetric control of light by subwavelength
    resonators paves the way towards novel nanophotonic components via dense integration
    of large quantities of nonlinear resonators into compact metasurface designs.
