text: In this paper we present a new system architecture for software-defined radio
/ radar with optical signal distribution. The proposed architecture allows to
transmit the optical carrier and an arbitrary IQ signal on the same fiber from
a base station to wireless transmitters using a single laser. Furthermore, we
can reuse parts, and under special conditions, also the complete optical output
of the base station for the IQ return path from the wireless receiver frontends
to the base station. Avoiding multiple lasers and fibers for the distribution
of the carrier and arbitrary signal from the base station to the frontend, and
avoiding the laser diode for the IQ return path from receiver frontends to the
base station reduces the hardware effort significantly. Finally, the system architecture
allows to integrate all components of the optoelectronic wireless frontend in
a single chip using silicon photonics technology.

text: "This paper experimentally investigates and interprets the e®ects of noise
and non-\r\nlinearity in a silicon photonic optical test structure. For the analysis
di®erent optoelectronic phase\r\nnoise measurement techniques are used. Our tests
focuses on the performance of integrated opti-\r\ncal test structures using femtosecond
pulses in the 1550nm spectral range. A primary objective\r\nis to understand the
behaviour of silicon photonic waveguides that can be further employed in the\r\nimplementation
of an optoelectronic phase-locked loop (OEPLL) in silicon photonics technology.\r\nA
comparison of our results, as well as a discussion on the di®erent optoelectronic
phase noise\r\nmeasurement techniques are presented. Our ¯ndings provide insights
that can be leveraged to\r\noptimize the design and performance of ultra-low phase
noise on-chip OEPLL systems locking\r\nto mode-locked laser (MLL) signals. In
the future such systems can be essential for advanced\r\ncommunication and sensing
applications."

text: 'An ultra-fast change of the absorption onset for zincblende gallium-nitride
(zb-GaN) (fundamental bandgap: 3.23 eV) is observed by investigating the imaginary
part of the dielectric function using time-dependent femtosecond pump–probe spectroscopic
ellipsometry between 2.9 and 3.7 eV. The 266 nm (4.66 eV) pump pulses induce a
large electron–hole pair concentration up to 4×1020cm−3, which shift the transition
energy between conduction and valence bands due to many-body effects up to ≈500 meV.
Here, the absorption onset increases due to band filling while the bandgap renormalization
at the same time decreases the bandgap. Additionally, the absorption of the pump-beam
creates a free-carrier profile within the 605 nm zb-GaN layer with high free-carrier
concentrations at the surface, and low concentrations at the interface to the
substrate. This leads to varying optical properties from the sample surface (high
transition energy) to substrate (low transition energy), which are taken into
account by grading analysis for an accurate description of the experimental data.
For this, a model describing the time- and position-dependent free-carrier concentration
is formulated by considering the relaxation, recombination, and diffusion of those
carriers. We provide a quantitative analysis of optical experimental data (ellipsometric
angles Ψ and Δ) as well as a plot for the time-dependent change of the imaginary
part of the dielectric function.'

text: In this work, we utilize thin dielectric meta-atoms placed on a silver substrate
to efficiently enhance and manipulate the third-harmonic generation. We theoretically
and experimentally reveal that when the structural symmetry of the meta-atom is
incompatible with the lattice symmetry of an array, some generalized nonlinear
geometric phases appear, which offers new possibilities for harmonic generation
control beyond the accessible symmetries governed by the selection rule. The underlying
mechanism is attributed to the modified rotation of the effective principal axis
of a dense meta-atom array, where the strong coupling among the units gives rise
to a generalized linear geometric phase modulation of the pump light. Therefore,
nonlinear geometric phases carried by third-harmonic emissions are the natural
result of the wave-mixing process among the modes excited at the fundamental frequency.
This mechanism further points out a new strategy to predict the nonlinear geometric
phases delivered by the nanostructures according to their linear responses. Our
design is simple and efficient and offers alternatives for the nonlinear meta-devices
that are capable of flexible photon generation and manipulation.

text: The alignment of liquid crystals on surfaces plays a central role
in optimizing their performances. In this work, a cutting-edge nano-lithography-based
method to control the local orientation of a thermotropic liquid crystal is applied
to easily available commercial standard materials and evaluated. Parallel nanogrooves
on a substrate, created through 3D nanoprinting in a negative-tone photoresin
optimized for two-photon polymerization are used for this purpose. Azimuthal anchoring
energies of the order from 10−6 J/m2
to 10−5 J/m2 are found, depending on
the spacing, width and depth of the grooves. In part, these values are larger
than those reported previously for another photopolymer. Both uniform alignment
and spatial patterns of different alignment directions can be realized. Electro-optic
studies confirm the suitability of the method for electrically addressable photonic
applications and indicate strong polar anchoring.

text: Geometric-phase dielectric meta-lenses made of silicon with high numerical
aperture and short focal lengths are fabricated and characterised. For circularly
polarised light, the same meta-lens can act as a converging or diverging lens,
depending on the handedness of the circular polarisation. This effect enables
application for optical tweezers that trap or release µm-size polymer beads floating
in a microfluidic channel on demand. An electrically addressable polarisation
converter based on liquid crystals may be used to switch between the two states
of polarisation, at which the light transmitted through the meta-lens is focused
(trapping) or defocussed (releasing), respectively.

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.

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: 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.

principle meanwhile gives rise to the crucial problem and challenge to protect
the metasurface from dust or clean the unavoidable contaminants during daily usage.
Here, taking advantage of the intelligent bioinspired surfaces which exhibit self-cleaning
properties, a versatile dielectric metasurface benefiting from the obtained superhydrophilic
or quasi-superhydrophobic states is shown. The design is realized by embedding
the metasurface inside a large area of wettability supporting structures, which
is highly efficient in fabrication, and achieves both optical and wettability
functionality at the same time. The superhydrophilic state enables an enhanced
optical response with water, while the quasi-superhydrophobic state imparts the
fragile antennas an ability to self-clean dust contamination. Furthermore, the
metasurface can be easily switched and repeated between these two wettability
or functional states by appropriate treatments in a repeatable way, without degrading
the optical performance. The proposed design strategy will bring new opportunities
to smart metasurfaces with improved optical performance, versatility, and physical
stability.

text: While plasmonic particles can provide optical resonances in a wide spectral
range from the lower visible up to the near-infrared, often, symmetry effects
are utilized to obtain particular optical responses. By breaking certain spatial
symmetries, chiral structures arise and provide robust chiroptical responses to
these plasmonic resonances. Here, we observe strong chiroptical responses in the
linear and nonlinear optical regime for chiral L-handed helicoid-III nanoparticles
and quantify them by means of an asymmetric factor, the so-called g-factor. We
calculate the linear optical g-factors for two distinct chiroptical resonances
to −0.12 and –0.43 and the nonlinear optical g-factors to −1.45 and −1.63. The
results demonstrate that the chirality of the helicoid-III nanoparticles is strongly
enhanced in the nonlinear regime.

text: AbstractTailored nanoscale quantum light
sources, matching the specific needs of use cases, are crucial building blocks
for photonic quantum technologies. Several different approaches to realize solid-state
quantum emitters with high performance have been pursued and different concepts
for energy tuning have been established. However, the properties of the emitted
photons are always defined by the individual quantum emitter and can therefore
not be controlled with full flexibility. Here we introduce an all-optical nonlinear
method to tailor and control the single photon emission. We demonstrate a laser-controlled
down-conversion process from an excited state of a semiconductor quantum three-level
system. Based on this concept, we realize energy tuning and polarization control
of the single photon emission with a control-laser field. Our results mark an
important step towards tailored single photon emission from a photonic quantum
system based on quantum optical principles.
