text: A key challenge in designing efficient optical phased arrays is the lack of
a well-designed radiator. This work explores horn antennas numerically optimized
to target high upward radiation efficiency to be employed in silicon-based phased
arrays capable of producing elegant radiation patterns in the far-field.

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: 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: 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: 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: 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: 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: 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: Gaussian-beam-like bundles of semi-guided waves propagating in a dielectric
slab can excite modes with high-order optical angular momentum supported by a
circular fiber. We consider a multimode step-index fiber with a high-index coating,
where the waves in the slab are evanescently coupled to the modes of the fiber.
Conditions for effective resonant interaction are identified. Based on a hybrid
analytical–numerical coupled mode model, our simulations predict that substantial
fractions of the input power can be focused into waves with specific orbital angular
momentum, of excellent purity, with a clear distinction between degenerate modes
with opposite vorticity.

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: A dielectric step-index optical fiber with tube-like profile is considered,
being positioned with a small gap on top of a dielectric slab waveguide. We propose
a 2.5-D hybrid analytical/numerical coupled mode model for the evanescent excitation
of the tube through semi-guided waves propagating in the slab at oblique angles.
The model combines the directional polarized modes supported by the slab with
analytic solutions for the TE-, TM-, and orbital-angular-momentum (OAM) modes
of the tube-shaped fiber. Implementational details of the scheme are discussed,
complemented by finite-element simulations for verification purposes. Our results
include configurations with resonant in-fiber excitation of OAM modes with large
orbital angular momentum and strong field enhancement.

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.
