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: 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: 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: 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.

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: Resonant evanescent coupling can be utilized to selectively excite orbital
angular momentum (OAM) modes of high angular order supported by a thin circular
dielectric rod. Our 2.5-D hybrid-analytical coupled mode model combines the vectorial
fields associated with the fundamental TE- and TM-modes of a standard silicon
photonics slab waveguide, propagating at oblique angles with respect to the rod
axis, and the hybrid modes supported by the rod. One observes an efficient resonant
interaction in cases where the common axial wavenumber of the waves in the slab
matches the propagation constant of one or more modes of the rod. For certain
modes of high angular order, the incident wave is able to transfer its directionality
to the field in the fiber, exciting effectively only one of a pair of degenerate
OAM modes

text: We model negative polarization, which is observed for planetary regoliths
at backscattering, solving a full wave problem of light scattering with a numerically
exact Discontinuous Galerkin Time Domain (DGTD) method. Pieces of layers with
the bulk packing density of particles close to 0.5 are used. The model particles
are highly absorbing and have irregular shapes and sizes larger than the wavelength
of light. This represents a realistic analog of low-albedo planetary regoliths.
Our simulations confirm coherent backscattering mechanism of the origin of negative
polarization. We show that angular profiles of polarization are stabilized if
the number of particles in a layer piece becomes larger than ten. This allows
application of our approach to the negative polarization modeling for planetary
regoliths.

text: Here we demonstrate a new, to the best of our knowledge, type of 3-dB coupler
that has an ultra-broadband operational range from 1300 to 1600 nm with low fabrication
sensitivity. The overall device size is 800 µm including in/out S-bend waveguides.
The coupler is an asymmetric non-uniform directional coupler that consists of
two tapered waveguides. One of the coupler arms is shifted by 100 µm in the propagation
direction, which results in a more wavelength-insensitive 3-dB response compared
to a standard (not shifted) coupler. Moreover, compared to a long adiabatic coupler,
we achieved a similar wavelength response at a 16-times-smaller device length.
The couplers were fabricated using the silicon nitride platform of Lionix International.
We also experimentally demonstrated an optical switch that is made by using two
of these couplers in a Mach–Zehnder interferometer configuration. According to
experimental results, this optical switch exhibits –10 dB of extinction ratio
over the 1500–1600 nm wavelength range. Our results indicate that this new type
of coupler holds great promise for various applications, including optical imaging,
telecommunications, and reconfigurable photonic processors where compact, fabrication-tolerant,
and wavelength-insensitive couplers are essential.

text: 'We review our results of numerical simulations of light scattering from different
systems of densely packed irregular particles. We consider spherical clusters,
thick layers and monolayers with realistic topologies and dimensions much larger
than the wavelength of light. The maximum bulk packing density of clusters is
0.5. A numerically exact solution of the electromagnetic problem is obtained using
the Discontinuous Galerkin Time Domain method and with application of high- performance
computing. We show that high packing density causes light localization in such
structures which makes an impact on the opposition phenomena: backscattering intensity
surge and negative linear polarization feature. Diffuse multiple scattering is
significantly reduced in the case of non-absorbing particles and near-field interaction
results in a percolation-like light transport determined by the topology of the
medium. With this the negative polarization feature caused by single scattering
gets enhanced if compared to lower density samples. We also confirm coherent double
scattering mechanism of negative polarization for light scattered from dense absorbing
slabs. In this case convergent result for the scattering angle polarization dependency
at backscattering can be obtained for a layer of just a few tens of particles
if they are larger than the wavelength.'

text: Optical traveling wave antennas offer unique opportunities to control and
selectively guide light into a specific direction, which renders them excellent
candidates for optical communication and sensing. These applications require state-of-the-art
engineering to reach optimized functionalities such as high directivity and radiation
efficiency, low sidelobe levels, broadband and tunable capabilities, and compact
design. In this work, we report on the numerical optimization of the directivity
of optical traveling wave antennas made from low-loss dielectric materials using
full-wave numerical simulations in conjunction with the particle swarm optimization
algorithm. The antennas are composed of a reflector and a director deposited on
a glass substrate, and an emitter placed in the feed gap between them serves as
an internal source of excitation. In particular, we analyze antennas with rectangular-
and horn-shaped directors made of either hafnium dioxide or silicon. The optimized
antennas produce highly directional emissions due to the presence of two dominant
guided TE modes in the director in addition to leaky modes. These guided modes
dominate the far-field emission pattern and govern the direction of the main lobe
emission, which predominately originates from the end facet of the director. Our
work also provides a comprehensive analysis of the modes, radiation patterns,
parametric influences, and bandwidths of the antennas, which highlights their
robust nature.

text: We study a double-scattering coherent mechanism of negative polarization (NP)
near opposition that is observed for powder-like surfaces. The problem is solved
numerically for absorbing structures with irregular constituents, cubes, spheres,
and ellipsoids larger than the wavelength of incident light. Our simulations show
that double scattering between two random irregular particles shows weak NP. Adding
one more particle significantly increases the relative contribution of double
scattering which enhances NP. Simulations with regular shapes and controlled geometric
parameters show that the interference mechanism is sensitive to the geometry of
the scattering system and can also result in no polarization or even strong enhancement
of positive polarization at backscattering.

text: Highly directive antennas with the ability of shaping radiation patterns in
desired directions are essential for efficient on-chip optical communication with
reduced cross talk. In this paper, we design and optimize three distinct broadband
traveling-wave tantalum pentoxide antennas exhibiting highly directional characteristics.
Our antennas contain a director and reflector deposited on a glass substrate,
which are excited by a dipole emitter placed in the feed gap between the two elements.
Full-wave simulations in conjunction with global optimization provide structures
with an enhanced linear directivity as high as 119 radiating in the substrate.
The high directivity is a result of the interplay between two dominant TE modes
and the leaky modes present in the antenna director. Furthermore, these low-loss
dielectric antennas exhibit a near-unity radiation efficiency at the operational
wavelength of 780 nm and maintain a broad bandwidth. Our numerical results are
in good agreement with experimental measurements from the optimized antennas fabricated
using a two-step electron-beam lithography, revealing the highly directive nature
of our structures. We envision that our antenna designs can be conveniently adapted
to other dielectric materials and prove instrumental for inter-chip optical communications
and other on-chip applications.

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 publication a novel method for far-field prediction from magnetic
Huygens box data based on the boundary element method (BEM) is presented. Two
examples are considered for the validation of this method. The first example represents
an electric dipole so that the obtained calculations can be compared to an analytical
solution. As a second example, a printed circuit board is considered and the calculated
far-field is compared to a fullwave simulation. In both cases, the calculations
for different field integral equations are under comparison, and the results indicate
that the presented method performs very well with a combined field integral equation,
for the specified problem, when only magnetic Huygens box data is given.
