  text: We present strong enhancement of third harmonic generation in an amorphous
    silicon metasurface consisting of elliptical nano resonators. We show that this
    enhancement originates from a new type of multi-mode Fano mechanism. These ‘Super-Fano’
    resonances are investigated numerically in great detail using full-wave simulations.
    The theoretically predicted behavior of the metasurface is experimentally verified
    by linear and nonlinear transmission spectroscopy. Moreover, quantitative nonlinear
    measurements are performed, in which an absolute conversion efficiency as high
    as ηmax ≈ 2.8 × 10−7 a peak power intensity of 1.2 GW cm−2 is found. Compared
    to an unpatterned silicon film of the same thickness amplification factors of
    up to ~900 are demonstrated. Our results pave the way to exploiting a strong Fano-type
    multi-mode coupling in metasurfaces for high THG in potential applications.

  text: The free exciton transition (near-band-edge emission, NBE) of ZnO at ≈388
    nm can be strongly enhanced and even stimulated by an underlying photonic structure.
    1D Photonic crystals, so-called distributed Bragg reflectors, are utilized to
    suppress the deep-level emission of ZnO (DLE, ≈500–530 nm). The reflector stacks
    are fabricated in a layer-by-layer procedure by wet-chemical synthesis. They consist
    of low-ε porous SiO2 layers and high-ε TiO2 layers. Varying the thickness of the
    SiO2 layers allows tuning the optical bandgap in a wide range between ≈420 and
    800 nm. A ZnO layer is deposited on top of the reflector stacks by sol–gel synthesis.
    The spontaneous photoluminescence (PL) emission of the ZnO film is modulated by
    the photonic structure. When the optical bandgap of the reflector is in resonance
    with the deep-level emission of ZnO (DLE, ≈500–530 nm), then this defect-related
    emission mode is suppressed. Strong NBE emission is observed even when the ZnO
    layer does not show any NBE emission (due to low crystallinity) in the absence
    of the photonic structure. With this cost-efficient synthesis method, emitters
    for, e.g., luminescent gas sensors can be fabricated.

  text: Lithium niobate on insulator (LNOI) has a great potential for photonic integrated
    circuits, providing substantial versatility in design of various integrated components.
    To properly use these components in the implementation of different quantum protocols,
    photons with different properties are required. In this paper, we theoretically
    demonstrate a flexible source of correlated photons built on the LNOI waveguide
    of a special geometry. This source is based on the parametric down-conversion
    (PDC) process, in which the signal and idler photons are generated at the telecom
    wavelength and have different spatial profiles and polarizations, but the same
    group velocities. Distinguishability in polarizations and spatial profiles facilitates
    the routing and manipulating individual photons, while the equality of their group
    velocities leads to the absence of temporal walk-off between photons. We show
    how the spectral properties of the generated photons and the number of their frequency
    modes can be controlled depending on the pump characteristics and the waveguide
    length. Finally, we discuss special regimes, in which narrowband light with strong
    frequency correlations and polarization-entangled Bell states are generated at
    the telecom wavelength.

  text: In this paper, silicon oxynitride films (SiON) grown by plasma-enhanced chemical
    vapor deposition are investigated. As precursor gases silane (SiH4), nitrous oxide
    (N2O), nitrogen (N2) and ammonia (NH3) are used with different compositions. We
    find that for achieving high nitrogen content adding ammonia to the precursor
    mix is most efficient. Moreover, we investigate the balance between adsorption
    and desorption processes during film growth by investigating the film growth rate
    as a function of the substrate temperature. From these data we are able to determine
    an effective activation energy for the film growth, corresponding to the difference
    between adsorption and desorption energy. Finally, we have thoroughly investigated
    the optical properties of the films using spectroscopic ellipsometry. From these
    measurements, we suggest a parametrized model for the refractive index and extinction
    coefficient in a wide range of compositions based on a Cauchy- and a Lorentz-fit.

  text: GaAs-(111)-nanostructures exhibiting second harmonic generation are new building
    blocks in nonlinear optics. Such structures can be fabricated through epitaxial
    lift-off using selective etching of Al-containing layers and subsequent transfer
    to glass substrates. Herein, the selective etching of (111)B-oriented AlxGa1−xAs
    sacrificial layers (10–50 nm thick) with different aluminum concentrations (x
    = 0.5–1.0) in 10\% hydrofluoric acid is investigated and compared with standard
    (100)-oriented structures. The thinner the sacrificial layer and the lower the
    aluminum content, the lower the lateral etch rate. For both orientations, the
    lateral etch rates are in the same order of magnitude, but some quantitative differences
    exist. Furthermore, the epitaxial lift-off, the transfer, and the nanopatterning
    of thin (111)B-oriented GaAs membranes are demonstrated. Atomic force microscopy
    and high-resolution X-ray diffraction measurements reveal the high structural
    quality of the transferred GaAs-(111) films.

  text: Plasmonic nanoantennas for visible and infrared radiation strongly improve
    the interaction of light with the matter on the nanoscale due to their strong
    near-field enhancement. In this study, we investigate a double-resonant plasmonic
    nanoantenna, which makes use of plasmonic field enhancement, enhanced outcoupling
    of second harmonic light, and resonant lattice effects. Using this design, we
    demonstrate how the efficiency of second harmonic generation can be increased
    significantly by fully embedding the nanoantennas into nonlinear dielectric material
    ZnO, instead of placing them on the surface. Investigating two different processes,
    we found that the best fabrication route is embedding the gold nanoantennas in
    ZnO using an MBE overgrowth process where a thin ZnO layer was deposited on nanoantennas
    fabricated on a ZnO substrate. In addition, second harmonic generation measurements
    show that the embedding leads to an enhancement compared to the emission of nanoantennas
    placed on the ZnO substrate surface. These promising results facilitate further
    research to determine the influence of the periodicity of the nanoantenna arrangement
    of the resulting SHG signal.

  text: Nonlinear Pancharatnam–Berry phase metasurfaces facilitate the nontrivial
    phase modulation for frequency conversion processes by leveraging photon‐spin
    dependent nonlinear geometric‐phases. However, plasmonic metasurfaces show some
    severe limitation for nonlinear frequency conversion due to the intrinsic high
    ohmic loss and low damage threshold of plasmonic nanostructures. Here, the nonlinear
    geometric‐phases associated with the third‐harmonic generation process occurring
    in all‐dielectric metasurfaces is studied systematically, which are composed of
    silicon nanofins with different in‐plane rotational symmetries. It is found that
    the wave coupling among different field components of the resonant fundamental
    field gives rise to the appearance of different nonlinear geometric‐phases of
    the generated third‐harmonic signals. The experimental observations of the nonlinear
    beam steering and nonlinear holography realized in this work by all‐dielectric
    geometric‐phase metasurfaces are well explained with the developed theory. This
    work offers a new physical picture to understand the nonlinear optical process
    occurring at nanoscale dielectric resonators and will help in the design of nonlinear
    metasurfaces with tailored phase properties.

  text: Free from phase-matching constraints, plasmonic metasurfaces have contributed
    significantly to the control of optical nonlinearity and enhancement of nonlinear
    generation efficiency by engineering subwavelength meta-atoms. However, high dissipative
    losses and inevitable thermal heating limit their applicability in nonlinear nanophotonics.
    All-dielectric metasurfaces, supporting both electric and magnetic Mie-type resonances
    in their nanostructures, have appeared as a promising alternative to nonlinear
    plasmonics. High-index dielectric nanostructures, allowing additional magnetic
    resonances, can induce magnetic nonlinear effects, which, along with electric
    nonlinearities, increase the nonlinear conversion efficiency. In addition, low
    dissipative losses and high damage thresholds provide an extra degree of freedom
    for operating at high pump intensities, resulting in a considerable enhancement
    of the nonlinear processes. We discuss the current state of the art in the intensely
    developing area of all-dielectric nonlinear nanostructures and metasurfaces, including
    the role of Mie modes, Fano resonances, and anapole moments for harmonic generation,
    wave mixing, and ultrafast optical switching. Furthermore, we review the recent
    progress in the nonlinear phase and wavefront control using all-dielectric metasurfaces.
    We discuss techniques to realize all-dielectric metasurfaces for multifunctional
    applications and generation of second-order nonlinear processes from complementary
    metal–oxide–semiconductor-compatible materials.
