text: We demonstrate for the first time, to the best of our knowledge, reconfigurable
and real-time orthogonal time-domain detection of a high-bandwidth Nyquist signal
with a low-bandwidth silicon photonics Mach-Zehnder modulator based receiver.
As the Nyquist signal has a rectangular bandwidth, it can be multiplexed in the
wavelength domain without any guardband as a part of a Nyquist-WDM superchannel.
These superchannels can be additionally multiplexed in space and polarization.
Thus, the presented demonstration can open a new possibility for the detection
of multidimensional parallel data signals with silicon photonics. No external
pulse source is needed for the receiver, and frequency-time coherence is used
to sample the incoming Nyquist signal with orthogonal sinc-shaped Nyquist pulse
sequences. All parameters are completely tunable in the electrical domain. The
feasibility of the scheme is demonstrated through a proof-of-concept experiment
over the entire C-band (1530 nm–1560 nm), employing a 24 Gbaud Nyquist QPSK signal
due to experimental constraints on the transmitter side electronics. However,
the silicon Mach-Zehnder modulator with a 3-dB bandwidth of only 16 GHz can process
Nyquist signals of 90 GHz optical bandwidth, suggesting a possibility to detect
symbol rates up to 90 GBd in an integrated Nyquist receiver.

text: The nonlinear process of second harmonic generation (SHG) in monolayer (1L)
transition metal dichalcogenides (TMD), like WS2, strongly depends on the polarization
state of the excitation light. By combination of plasmonic nanostructures with
1L-WS2 by transferring it onto a plasmonic nanoantenna array, a hybrid metasurface
is realized impacting the polarization dependency of its SHG. Here, we investigate
how plasmonic dipole resonances affect the process of SHG in plasmonic–TMD hybrid
metasurfaces by nonlinear spectroscopy. We show that the polarization dependency
is affected by the lattice structure of plasmonic nanoantenna arrays as well as
by the relative orientation between the 1L-WS2 and the individual plasmonic nanoantennas.
In addition, such hybrid metasurfaces show SHG in polarization states, where SHG
is usually forbidden for either 1L-WS2 or plasmonic nanoantennas. By comparing
the SHG in these channels with the SHG generated by the hybrid metasurface components,
we detect an enhancement of the SHG signal by a factor of more than 40. Meanwhile,
an attenuation of the SHG signal in usually allowed polarization states is observed.
Our study provides valuable insight into hybrid systems where symmetries strongly
affect the SHG and enable tailored SHG in 1L-WS2 for future applications.

text: Secret sharing is a well-established cryptographic primitive for storing
highly sensitive information like encryption keys for encoded data. It describes
the problem of splitting a secret into different shares, without revealing any
information to its shareholders. Here, we demonstrate an all-optical solution
for secret sharing based on metasurface holography. In our concept, metasurface
holograms are used as spatially separable shares that carry encrypted messages
in the form of holographic images. Two of these shares can be recombined by bringing
them close together. Light passing through this stack of metasurfaces accumulates
the phase shift of both holograms and optically reconstructs the secret with high
fidelity. In addition, the hologram generated by each single metasurface can uniquely
identify its shareholder. Furthermore, we demonstrate that the inherent translational
alignment sensitivity between two stacked metasurface holograms can be used for
spatial multiplexing, which can be further extended to realize optical rulers.

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: Topological states of light represent counterintuitive optical modes localized
at boundaries of finite-size optical structures that originate from the properties
of the bulk. Being defined by bulk properties, such boundary states are insensitive
to certain types of perturbations, thus naturally enhancing robustness of photonic
circuitries. Conventionally, the N-dimensional bulk modes correspond to (N – 1)-dimensional
boundary states. The higher-order bulk-boundary correspondence relates N-dimensional
bulk to boundary states with dimensionality reduced by more than 1. A special
interest lies in miniaturization of such higher-order topological states to the
nanoscale. Here, we realize nanoscale topological corner states in metasurfaces
with C6-symmetric honeycomb lattices. We directly observe nanoscale topology-empowered
edge and corner localizations of light and enhancement of light–matter interactions
via a nonlinear imaging technique. Control of light at the nanoscale empowered
by topology may facilitate miniaturization and on-chip integration of classical
and quantum photonic devices.

text: We realize and investigate a nonlinear metasurface taking advantage of intersubband
transitions in ultranarrow GaN/AlN multi-quantum well heterostructures. Owing
to huge band offsets, the structures offer resonant transitions in the telecom
window around 1.55 µm. These heterostructures are functionalized with an array
of plasmonic antennas featuring cross-polarized resonances at these near-infrared
wavelengths and their second harmonic. This kind of nonlinear metasurface allows
for substantial second-harmonic generation at normal incidence which is completely
absent for an antenna array without the multi-quantum well structure underneath.
While the second harmonic is originally radiated only into the plane of the quantum
wells, a proper geometrical arrangement of the plasmonic elements permits the
redirection of the second-harmonic light to free-space radiation, which is emitted
perpendicular to the surface.

text: "Photonic quantum technologies [1] with applications in quantum\r\ncommunication,
sensing as well as quantum simulation and computing, are on the\r\nverge of becoming
commercially available. One crucial building block are\r\ntailored nanoscale integratable
quantum light sources, matching the specific\r\nneeds of use-cases. Several different
approaches to realize solid-state quantum\r\nemitters [2] with high performance
[3] have been pursued. However, the\r\nproperties of the emitted single photons
are always defined by the individual\r\nquantum light source and despite numerous
quantum emitter tuning\r\ntechniques [4-7], scalability is still a major challenge.
Here we show an\r\nemitter-independent method to tailor and control the properties
of the single\r\nphoton emission. We demonstrate a laser-controlled down-conversion
process from\r\nan excited state of a quantum three-level system [8]. Starting
from a biexciton\r\nstate, a tunable control laser field defines a virtual state
in a stimulated\r\nprocess. From there, spontaneous emission to the ground state
leads to\r\noptically controlled single photon emission. Based on this concept,
we\r\ndemonstrate energy tuning of the single photon emission with a control laser\r\nfield.
The nature of the involved quantum states furthermore provides a unique\r\nbasis
for the future control of polarization and bandwidth, as predicted by\r\ntheory
[9,10]. Our demonstration marks an important step towards tailored\r\nsingle photon
emission from a photonic quantum system based on quantum optical\r\nprinciples."

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: AbstractThe coherent electron spin dynamics
of an ensemble of singly charged (In,Ga)As/GaAs quantum dots in a transverse magnetic
field is driven by periodic optical excitation at 1 GHz repetition frequency.
Despite the strong inhomogeneity of the electron g
factor, the spectral spread of optical transitions, and the broad distribution
of nuclear spin fluctuations, we are able to push the whole ensemble of excited
spins into a single Larmor precession mode that is commensurate with the laser
repetition frequency. Furthermore, we demonstrate that an optical detuning of
the pump pulses from the probed optical transitions induces a directed dynamic
nuclear polarization and leads to a discretization of the total magnetic field
acting on the electron ensemble. Finally, we show that the highly periodic optical
excitation can be used as universal tool for strongly reducing the nuclear spin
fluctuations and preparation of a robust nuclear environment for subsequent manipulation
of the electron spins, also at varying operation frequencies.

text: Topological photonic crystals (TPhCs) provide robust manipulation of light
with built-in immunity to fabrication tolerances and disorder. Recently, it was
shown that TPhCs based on weak topology with a dislocation inherit this robustness
and further host topologically protected lower-dimensional localized modes. However,
TPhCs with weak topology at optical frequencies have not been demonstrated so
far. Here, we use scattering-type scanning near-field optical microscopy to verify
mid-bandgap zero-dimensional light localization close to 100 THz in a TPhC with
nontrivial Zak phase and an edge dislocation. We show that because of the weak
topology, differently extended dislocation centers induce similarly strong light
localization. The experimental results are supported by full-field simulations.
Along with the underlying fundamental physics, our results lay a foundation for
the application of TPhCs based on weak topology in active topological nanophotonics,
and nonlinear and quantum optic integrated devices because of their strong and
robust light localization.

text: We show that narrow trenches in a high-contrast silicon-photonics slab can
act as lossless power dividers for semi-guided waves. Reflectance and transmittance
can be easily configured by selecting the trench width. At sufficiently high angles
of incidence, the devices are lossless, apart from material attenuation and scattering
due to surface roughness. We numerically simulate a series of devices within the
full 0-to-1-range of splitting ratios, for semi-guided plane wave incidence as
well as for excitation by focused Gaussian wave bundles. Straightforward cascading
of the trenches leads to concepts for 1×M-power dividers and a polarization beam
splitter.

text: Optical metasurfaces are perfect candidates for the phase and amplitude modulation
of light, featuring an excellent basis for holographic applications. In this work,
we present a dual amplitude holographic scheme based on the photon sieve principle,
which is then combined with a phase hologram by utilizing the Pancharatnam–Berry
phase. We demonstrate that two types of apertures, rectangular and square shapes
in a gold film filled with silicon nanoantennas are sufficient to create two amplitude
holograms at two different wavelengths in the visible, multiplexed with an additional
phase-only hologram. The nanoantennas are tailored to adjust the spectral transmittance
of the apertures, enabling the wavelength sensitivity. The phase-only hologram
is implemented by utilizing the anisotropic rectangular structure. Interestingly,
such three holograms have quantitative mathematical correlations with each other.
Thus, the flexibility of polarization and wavelength channels can be utilized
with custom-tailored features to achieve such amplitude and phase holography simultaneously
without sacrificing any space-bandwidth product. The present scheme has the potential
to store different pieces of information which can be displayed separately by
switching the wavelength or the polarization state of the reading light beam.

text: We demonstrate the integration of amorphous tungsten silicide superconducting
nanowire single-photon detectors on titanium in-diffused lithium niobate waveguides.
We show proof-of-principle detection of evanescently coupled photons of 1550 nm
wavelength using bidirectional waveguide coupling for two orthogonal polarization
directions. We investigate the internal detection efficiency as well as detector
absorption using coupling-independent characterization measurements. Furthermore,
we describe strategies to improve the yield and efficiency of these devices.

text: AbstractColloidal nanosphere monolayers—used
as a lithography mask for site-controlled material deposition or removal—offer
the possibility of cost-effective patterning of large surface areas. In the present
study, an automated analysis of scanning electron microscopy (SEM) images is described,
which enables the recognition of the individual nanospheres in densely packed
monolayers in order to perform a statistical quantification of the sphere size,
mask opening size, and sphere-sphere separation distributions. Search algorithms
based on Fourier transformation, cross-correlation, multiple-angle intensity profiling,
and sphere edge point detection techniques allow for a sphere detection efficiency
of at least 99.8%, even in the case of considerable sphere size variations. While
the sphere positions and diameters are determined by fitting circles to the spheres
edge points, the openings between sphere triples are detected by intensity thresholding.
For the analyzed polystyrene sphere monolayers with sphere sizes between 220 and
600 nm and a diameter spread of around 3% coefficients of variation of 6.8–8.1%
for the opening size are found. By correlating the mentioned size distributions,
it is shown that, in this case, the dominant contribution to the opening size
variation stems from nanometer-scale positional variations of the spheres.
