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.

In planar microcavities, the transverse-electric and transverse-magnetic
(TE-TM) mode splitting of cavity photons arises due to their different
penetration into the Bragg mirrors and can result in optical spin-orbit
coupling (SOC). In this work, we find that in a liquid crystal (LC) microcavity
filled with perovskite microplates, the pronounced TE-TM splitting gives rise
to a strong SOC that leads to the spatial instability of microcavity polariton
condensates under single-shot excitation. Spatially varying hole burning and
mode competition occurs between polarization components leading to different
condensate profiles from shot to shot. The single-shot polariton condensates
become stable when the SOC vanishes as the TE and TM modes are spectrally well
separated from each other, which can be achieved by application of an electric
field to our LC microcavity with electrically tunable anisotropy. Our findings
are well reproduced and traced back to their physical origin by our detailed
numerical simulations. With the electrical manipulation our work reveals how
the shot-to-shot spatial instability of spatial polariton profiles can be
engineered in anisotropic microcavities at room temperature, which will benefit
the development of stable polariton-based optoeletronic and light-emitting
devices.

The control and active manipulation of spin-orbit coupling (SOC) in photonic
systems is fundamental in the development of modern spin optics and topological
photonic devices. Here, we demonstrate the control of an artificial
Rashba-Dresselhaus (RD) SOC mediated by photochemical reactions in a
microcavity filled with an organic single-crystal of photochromic phase-change
character. Splitting of the circular polarization components of the optical
modes induced by photonic RD SOC is observed experimentally in momentum space.
By applying an ultraviolet light beam, we control the spatial molecular
orientation through a photochemical reaction and with that we control the
energies of the photonic modes. This way we realize a reversible conversion of
spin-splitting of the optical modes with different energies, leading to an
optically controlled switching between circularly and linearly polarized
emission from our device. Our strategy of in situ and reversible engineering of
SOC induced by a light field provides a promising approach to actively design
and manipulate synthetic gauge fields towards future on-chip integration in
photonics and topological photonic devices.

text: "Topological states have been widely investigated in different types of\r\nsystems
and lattices. In the present work, we report on topological edge states\r\nin
double-wave (DW) chains, which can be described by a generalized\r\nAubry-Andr\\'e-Harper
(AAH) model. For the specific system of a\r\ndriven-dissipative exciton polariton
system we show that in such potential\r\nchains, different types of edge states
can form. For resonant optical\r\nexcitation, we further find that the optical
nonlinearity leads to a\r\nmultistability of different edge states. This includes
topologically protected\r\nedge states evolved directly from individual linear
eigenstates as well as\r\nadditional edge states that originate from nonlinearity-induced
localization of\r\nbulk states. Extending the system into two dimensions (2D)
by stacking\r\nhorizontal DW chains in the vertical direction, we also create
2D multi-wave\r\nlattices. In such 2D lattices multiple Su-Schrieffer-Heeger (SSH)
chains appear\r\nalong the vertical direction. The combination of DW chains in
the horizontal\r\nand SSH chains in the vertical direction then results in the
formation of\r\nhigher-order topological insulator corner states."

Exceptional points (EPs) with their intriguing spectral topology have
attracted considerable attention in a broad range of physical systems, with
potential sensing applications driving much of the present research in this
field. Here we theoretically demonstrate the realization of EPs in a system
with significant nonlinearity, a non-equilibrium exciton-polariton condensate.
With the possibility to control loss and gain and nonlinearity by optical
means, this system allows for a comprehensive analysis of the interplay of
nonlinearities (Kerr-type and saturable gain) and non-Hermiticity. Not only do
we find that EPs can be intentionally shifted in parameter space by the
saturable gain, we also observe intriguing rotations and intersections of
Riemann surfaces, and find nonlinearity-enhanced sensing capabilities. Our
results are quite general in nature and illustrate the potential of tailoring
spectral topology and related phenomena in non-Hermitian systems by
nonlinearity.

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.
