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: The nonlinear optical response of an ensemble of semiconductor quantum dots
is analyzed by wave-mixing processes, where we focus on four-wave mixing with
two incident pulses. Wave-mixing experiments are often described with semiclassical
models, where the light is modeled classically and the material quantum mechanically.
Here, however, we use a fully quantized model, where the light is given by a quantum
state of light. Quantum light involves more degrees of freedom than classical
light as e.g., its photon statistics and quantum correlations, which is a promising
resource for quantum devices, such as quantum memories. The light-matter interaction
is treated with a Jaynes-Cummings type model and the quantum field is given by
a single mode since the quantum dots are embedded in a microcavity. We present
numerical simulations of the four-wave-mixing response of a homogeneous system
for pulse sequences and find a significant dependence of the result on the photon
statistics of the incident pulses. The model constitutes a problem with a large
state space which arises from the frequency distribution of the transition energies
of the inhomogeneously broadened quantum dot ensemble that is coupled with a quantum
light mode. Here we approximate the dynamics by summing over individual quantum
dot-microcavity systems. Photon echoes arising from the excitation with different
quantum states of light are simulated and compared.

text: Since high-order harmonic generation (HHG) from atoms depends sensitively
on the polarization of the driving laser field, the polarization gating (PG) technique
was developed and applied successfully to generate isolated attosecond pulses
from atomic gases. The situation is, however, different in solid-state systems
as it has been demonstrated that due to collisions with neighboring atomic cores
of the crystal lattice strong HHG can be generated even by elliptically- and circularly-polarized
laser fields. Here we apply PG to solid-state systems and find that the conventional
PG technique is inefficient for the generation of isolated ultrashort harmonic
pulse bursts. In contrast, we demonstrate that a polarization-skewed laser pulse
is able to confine the harmonic emission to a time window of less than one-tenth
of the laser cycle. This method provides a novel way to control HHG and to generate
isolated attosecond pulses in solids.

text: A series of new organic donor–π–acceptor dyes incorporating a diquat moiety
as a novel electron-acceptor unit have been synthesized and characterized. The
analytical data were supported by DFT calculations. These dyes were explored in
the aerobic thiocyanation of indoles and pyrroles. Here they showed a high photocatalytic
activity under visible light, giving isolated yields of up to 97 %. In addition,
the photocatalytic activity of standalone diquat and methyl viologen through formation
of an electron donor acceptor complex is presented.

text: Perfect vector vortex beams (PVVBs) have attracted considerable interest due
to their peculiar optical features. PVVBs are typically generated through the
superposition of perfect vortex beams, which suffer from the limited number of
topological charges (TCs). Furthermore, dynamic control of PVVBs is desirable
and has not been reported. We propose and experimentally demonstrate hybrid grafted
perfect vector vortex beams (GPVVBs) and their dynamic control. Hybrid GPVVBs
are generated through the superposition of grafted perfect vortex beams with a
multifunctional metasurface. The generated hybrid GPVVBs possess spatially variant
rates of polarization change due to the involvement of more TCs. Each hybrid GPVVB
includes different GPVVBs in the same beam, adding more design flexibility. Moreover,
these beams are dynamically controlled with a rotating half waveplate. The generated
dynamic GPVVBs may find applications in the fields where dynamic control is in
high demand, including optical encryption, dense data communication, and multiple
particle manipulation.

text: Interference between single photons is key for many quantum optics experiments
and applications in quantum technologies, such as quantum communication or computation.
It is advantageous to operate the systems at telecommunication wavelengths and
to integrate the setups for these applications in order to improve stability,
compactness and scalability. A new promising material platform for integrated
quantum optics is lithium niobate on insulator (LNOI). Here, we realise Hong-Ou-Mandel
(HOM) interference between telecom photons from an engineered parametric down-conversion
source in an LNOI directional coupler. The coupler has been designed and fabricated
in house and provides close to perfect balanced beam splitting. We obtain a raw
HOM visibility of (93.5 ± 0.7) %, limited mainly by the source performance and
in good agreement with off-chip measurements. This lays the foundation for more
sophisticated quantum experiments in LNOI.

text: This work reports a fully guided setup for single-mode squeezing on
integrated titanium-indiffused periodically poled nonlinear resonators. A continuous-wave
laser beam is delivered and the squeezed field is collected by single-mode fibers;
up to −3.17(9) dB of useful squeezing is available in fibers. To showcase the
usefulness of such a fiber-coupled device, we applied the generated squeezed light
in a fiber-based phase sensing experiment, showing a quantum enhancement in the
signal-to-noise ratio of 0.35 dB. Moreover, our investigation of the effect of
photorefraction on the cavity resonance condition suggests that it causes system
instabilities at high powers.

text: 'Site-controlled Ga droplets on AlGaAs substrates are fabricated using
area-selective deposition of Ga through apertures in a mask during molecular beam
epitaxy (MBE). The Ga droplets can be crystallized into GaAs quantum dots using
a crystallization step under As flux. In order to model the complex process, including
the masked deposition of the droplets and a reduction of their number during a
thermal annealing step, a multiscale kinetic Monte Carlo (mkMC) simulation of
self-assembled Ga droplet formation on AlGaAs is expanded for area-selective deposition.
The simulation has only two free model parameters: the activation energy for surface
diffusion and the activation energy for thermal escape of adatoms from a droplet.
Simulated droplet numbers within the opening of the aperture agree quantitatively
with the experimental results down to the perfect site-control, with one droplet
per aperture. However, the model parameters are different compared to those of
the self-assembled droplet growth. We attribute this to the presence of the mask
in close proximity to the surface, which modifies the local process temperature
and the As background. This approach also explains the dependence of the model
parameters on the size of the aperture.'

text: We present the fabrication of strain-free quantum dots in the In0.53Ga0.47As/In0.52Al0.48As-system
lattice matched to InP, as future sources for single and entangled photons for
long-haul fiber-based quantum communication in the optical C-band. We achieved
these quantum dots by local droplet etching via InAl droplets in an In0.52Al0.48As
layer and subsequent filling of the holes with In0.53Ga0.47As. Here, we present
detailed investigations of the hole morphologies measured by atomic force microscopy.
Statistical analysis of a set of nanoholes reveals a high degree of symmetry for
nearly half of them when etched at optimized temperatures. Overgrowth with 50–150 nm
In0.52Al0.48As increases their diameter and elongates the holes along the [01̄1]-direction.
By systematically scanning the parameter space, we were able to fill the holes
with In0.53Ga0.47As, and by capping the filled holes and performing photoluminescence
measurements, we observe photoluminescence emission in the O-band up into the
C-band depending on the filling height of the nanoholes.

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: 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.
