text: 'We explore the polarization hysteretic behaviour and field-dependent permittivity
of ferroelectric-dielectric 2D materials formed by random dispersions of low permittivity
inclusions in a ferroelectric matrix, using finite element simulations. We show
how the degree of impenetrability of dielectric inclusions plays a substantial
role in controlling the coercive field, remnant and saturation polarizations of
the homogenized materials. The results highlight the significance of the degree
of impenetrability of inclusion in tuning the effective polarization properties
of such ferroelectric composites: coercive field drops significantly as percolation
threshold is attained and remnant polarization decreases faster than a linear
decay.'

text: We demonstrate the numerical and experimental realization of optimized optical
traveling-wave antennas made of low-loss dielectric materials. These antennas
exhibit highly directive radiation patterns and our studies reveal that this nature
comes from two dominant guided TE modes excited in the waveguide-like director
of the antenna, in addition to the leaky modes. The optimized antennas possess
a broadband nature and have a nearunity radiation efficiency at an operational
wavelength of 780 nm. Compared to the previously studied plasmonic antennas for
photon emission, our all-dielectric approach demonstrates a new class of highly
directional, low-loss, and broadband optical antennas.

text: We demonstrate a large-scale two dimensional silicon-based optical phased
array (OPA) composed of nanoantennas with circular gratings that are balanced
in power and aligned in phase, required for producing desired radiation patterns
in the far-field. The OPAs are numerically optimized to have an upward efficiency
of up to 90%, targeting radiation concentration mainly in the field of view. We
envision that our OPAs have the ability of generating complex holographic images,
rendering them an attractive candidate for a wide range of applications like LiDAR
sensors, optical trapping, optogenetic stimulation and augmented-reality displays.

text: High-contrast slab waveguide Bragg gratings with 1D periodicity are investigated.
For specific oblique excitation by semi-guided waves at sufficiently high angles
of incidence, the idealized structures do not exhibit any radiative losses, such
that reflectance and transmittance for the single port mode add strictly up to
one. We consider a series of symmetric, fully and partly etched finite gratings,
for parameters found in integrated silicon photonics. These can act as spectral
filters with a reasonably flattop response. Apodization can lead to more box shaped
reflectance and transmittance spectra. Together with a narrowband Fabry–Perot
filter, these configurations are characterized by reflection bands, or transmittance
peaks, with widths that span three orders of magnitude.

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: Dielectric metasurfaces provide a unique platform for efficient harmonic generation
and optical wavefront manipulation at the nanoscale. Tailoring phase and amplitude
of a nonlinearly generated wave with a high emission efficiency using resonance-based
metasurfaces is a challenging task that often requires state-of-the-art numerical
methods. Here, we propose a simple yet effective approach combining a sampling
method with a Monte Carlo approach to design the third-harmonic wavefront generated
by all-dielectric metasurfaces composed of elliptical silicon nanodisks. Using
this approach, we theoretically demonstrate the full nonlinear 2π phase control
with a uniform and highest possible amplitude in the considered parameter space,
allowing us to design metasurfaces operating as third harmonic beam deflectors
capable of steering light into a desired direction with high emission efficiency.
The TH beam deflection with a record calculated average conversion efficiency
of 1.2 × 10–1 W–2 is achieved. We anticipate that the proposed approach will be
widely applied as alternative to commonly used optimization algorithms with higher
complexity and implementation effort for the design of metasurfaces with other
holographic functionalities.

text: Silicon photonics, in conjunction with complementary metal-oxide-semiconductor
(CMOS) fabrication, has greatly enhanced the development of integrated optical
phased arrays. This facilitates a dynamic control of light in a compact form factor
that enables the synthesis of arbitrary complex wavefronts in the infrared spectrum.
We numerically demonstrate a large-scale two-dimensional silicon-based optical
phased array (OPA) composed of nanoantennas with circular gratings that are balanced
in power and aligned in phase, required for producing elegant radiation patterns
in the far-field. For a wavelength of 1.55 μm, we optimize two antennas for the
OPA exhibiting an upward radiation efficiency as high as 90%, with almost 6.8%
of optical power concentrated in the field of view. Additionally, we believe that
the proposed OPAs can be easily fabricated and would have the ability to generate
complex holographic images, rendering them an attractive candidate for a wide
range of applications like LiDAR sensors, optical trapping, optogenetic stimulation,
and augmented-reality displays.

text: In this paper, the influence of the environment on an inductive location system
is analyzed. In the inductive location method, high frequency magnetic fields
generated by planar coils lead to induction in other coils, which is used for
localization analysis. Magnetic fields are not affected by changes in the dielectric
properties of the environment, which is an advantage over other localization methods.
However, electrical material parameters can still affect the localization results
by indirect effects. For this reason, in this publication the influence will be
investigated using real material parameters and their effects on the localization
will be considered, so that the robustness and the limits of the inductive localization
can be evaluated.

text: AbstractThe biexciton‐exciton emission cascade
commonly used in quantum‐dot systems to generate polarization entanglement yields
photons with intrinsically limited indistinguishability. In the present work,
it focuses on the generation of pairs of photons with high degrees of polarization
entanglement and simultaneously high indistinguishability. It achieves this goal
by selectively reducing the biexciton lifetime with an optical resonator. It demonstrates
that a suitably tailored circular Bragg reflector fulfills the requirements of
sufficient selective Purcell enhancement of biexciton emission paired with spectrally
broad photon extraction and twofold degenerate optical modes. The in‐depth theoretical
study combines (i) the optimization of realistic photonic structures solving Maxwell's
equations from which model parameters are extracted as input for (ii) microscopic
simulations of quantum‐dot cavity excitation dynamics with full access to photon
properties. It reports non‐trivial dependencies on system parameters and use the
predictive power of the combined theoretical approach to determine the optimal
range of Purcell enhancement that maximizes indistinguishability and entanglement
to near unity values, here specifically for the telecom C‐band at 1550 nm.
