text: Metasurfaces provide applications for a variety of flat elements and devices
due to the ability to modulate light with subwavelength structures. The working
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: Optical geometric phase encoded by in-plane spatial orientation of microstructures
has promoted the rapid development of numerous functional meta-devices. However,
pushing the concept of the geometric phase toward the acoustic community still
faces challenges. In this work, we utilize two acoustic nonlocal metagratings
that could support a direct conversion between an acoustic plane wave and a designated
vortex mode to obtain the acoustic geometric phase, in which an orbital angular
momentum conversion process plays a vital role. In addition, we realize the acoustic
geometric phases of different orders by merely varying the orientation angle of
the acoustic nonlocal metagratings. Intriguingly, according to our developed theory,
we reveal that the reflective acoustic geometric phase, which is twice the transmissive
one, can be readily realized by transferring the transmitted configuration to
a reflected one. Both the theoretical study and experimental measurements verify
the announced transmissive and reflective acoustic geometric phases. Moreover,
the reconfigurability and continuous phase modulation that covers the 2π range
shown by the acoustic geometric phases provide us with the alternatives in advanced
acoustic wavefront control.

text: With the rapid advances of functional dielectric metasurfaces and their integration
on on-chip nanophotonic devices, the necessity of metasurfaces working in different
environments, especially in biological applications, arose. However, the metasurfaces’
performance is tied to the unit cell’s efficiency and ultimately the surrounding
environment it was designed for, thus reducing its applicability if exposed to
altering refractive index media. Here, we report a method to increase a metasurface’s
versatility by covering the high-index metasurface with a low index porous SiO2
film, protecting the metasurface from environmental changes while keeping the
working efficiency unchanged. We show, that a covered metasurface retains its
functionality even when exposed to fluidic environments.

text: Inspired by plant grafting, grafted vortex beams can be formed through grafting
two or more helical phase profiles of optical vortex beams. Recently, grafted
perfect vortex beams (GPVBs) have attracted much attention due to their unique
optical properties and potential applications. However, the current method to
generate and manipulate GPVBs requires a complex and bulky optical system, hindering
further investigation and limiting its practical applications. Here, a compact
metasurface approach for generating and manipulating GPVBs in multiple channels
is proposed and demonstrated, which eliminates the need for such a complex optical
setup. A single metasurface is utilized to realize various superpositions of GPVBs
with different combinations of topological charges in four channels, leading to
asymmetric singularity distributions. The positions of singularities in the superimposed
beam can be further modulated by introducing an initial phase difference in the
metasurface design. The work demonstrates a compact metasurface platform that
performs a sophisticated optical task that is very challenging with conventional
optics, opening opportunities for the investigation and applications of GPVBs
in a wide range of emerging application areas, such as singular optics and quantum
science.

text: Subwavelength dielectric resonators assembled into metasurfaces have become
a versatile tool for miniaturizing optical components approaching the nanoscale.
An important class of metasurface functionalities is associated with asymmetry
in both the generation and transmission of light with respect to reversals of
the positions of emitters and receivers. The nonlinear light–matter interaction
in metasurfaces offers a promising pathway towards miniaturization of the asymmetric
control of light. Here we demonstrate asymmetric parametric generation of light
in nonlinear metasurfaces. We assemble dissimilar nonlinear dielectric resonators
into translucent metasurfaces that produce images in the visible spectral range
on being illuminated by infrared radiation. By design, the metasurfaces produce
different and completely independent images for the reversed direction of illumination,
that is, when the positions of the infrared emitter and the visible light receiver
are exchanged. Nonlinearity-enabled asymmetric control of light by subwavelength
resonators paves the way towards novel nanophotonic components via dense integration
of large quantities of nonlinear resonators into compact metasurface designs.

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: 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: 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: 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: AbstractQuantum well (QW) heterostructures
have been extensively used for the realization of a wide range of optical and
electronic devices. Exploiting their potential for further improvement and development
requires a fundamental understanding of their electronic structure. So far, the
most commonly used experimental techniques for this purpose have been all-optical
spectroscopy methods that, however, are generally averaging in momentum space.
Additional information can be gained by angle-resolved photoelectron spectroscopy
(ARPES), which measures the electronic structure with momentum resolution. Here
we report on the use of extremely low-energy ARPES (photon energy ~ 7 eV) to increase
depth sensitivity and access buried QW states, located at 3 nm and 6 nm below
the surface of cubic-GaN/AlN and GaAs/AlGaAs heterostructures, respectively. We
find that the QW states in cubic-GaN/AlN can indeed be observed, but not their
energy dispersion, because of the high surface roughness. The GaAs/AlGaAs QW states,
on the other hand, are buried too deep to be detected by extremely low-energy
ARPES. Since the sample surface is much flatter, the ARPES spectra of the GaAs/AlGaAs
show distinct features in momentum space, which can be reconducted to the band
structure of the topmost surface layer of the QW structure. Our results provide
important information about the samples’ properties required to perform extremely
low-energy ARPES experiments on electronic states buried in semiconductor heterostructures.

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.
