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: 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.

text: Resonant evanescent coupling can be utilized to selectively excite orbital
angular momentum (OAM) modes of high angular order supported by a thin circular
dielectric rod. Our 2.5-D hybrid-analytical coupled mode model combines the vectorial
fields associated with the fundamental TE- and TM-modes of a standard silicon
photonics slab waveguide, propagating at oblique angles with respect to the rod
axis, and the hybrid modes supported by the rod. One observes an efficient resonant
interaction in cases where the common axial wavenumber of the waves in the slab
matches the propagation constant of one or more modes of the rod. For certain
modes of high angular order, the incident wave is able to transfer its directionality
to the field in the fiber, exciting effectively only one of a pair of degenerate
OAM modes

text: In dieser Arbeit wird die elektromagnetische Wellenausbreitung in integrierten

untersucht. Im ersten Teil werden 2-D Si/SiO2-Wellenleiterkonfigurationen mit
hohem Brechungsindexkontrast betrachtet. Die Strukturen werden mit halb geführten
Wellen unter schrägen Ausbreitungswinkeln angeregt. Dadurch kann die Leistungsübertragung
zu bestimmten ausgehenden Moden unterdrückt werden, wodurch vollständig verlustfreie
Systeme entstehen. Zusätzlich dient die Anregung mit einem seitlich begrenzten,
einfallenden Wellenbündel aus halb geführten Wellen dazu, praktisch relevantere
3-D Konfigurationen zu realisieren. Darüber hinaus wird eine schrittweise Winkelspektrum-Methode
vorgestellt, die es ermöglicht, in Kombination mit voll vektoriellen 2-D Finite-Elemente-Lösungen
für Teilprobleme mit geringerer Komplexität, die Wellenausbreitung in planaren,
linsenförmigen Wellenleitern numerisch in drei Raumrichtungen zu berechnen. Im
zweiten Teil dieser Arbeit wird die Ausbreitung in Wellenleiterstrukturen aus
Lithiumniobat untersucht, welche für quantenoptische Effekte genutzt werden. Zur
Detektion einzelner Photonen werden supraleitende Nanodrähte auf eindiffundierten
Lithiumniobat Wellenleitern mit zusätzlicher Taperschicht aus Silizium betrachtet.
Um die Wellenausbreitung in diesen 3-D Wellenleitern zu beschreiben, wird eine
einseitig gerichtete Finite-Elemente „Modal Matching“ Methode eingeführt. Abschließend
werden Rippenwellenleiter aus Lithiumniobat analysiert, die auf Siliziumdioxid
Plattformen aufgebracht sind. Der Schwerpunkt liegt hier auf dem nichtlinearen
„Parametric Down-Conversion“ Prozess, der für die Erzeugung verschränkter Photonen
verwendet wird.

text: In this work, the electromagnetic wave propagation in integrated optical waveguides
is studied by using semi-analytical and numerical simulation methods. In the first
part, 2-D high-index contrast Si/SiO2 dielectric slab waveguide configurations
are investigated. The structures are excited with semi-guided waves at oblique
angles of propagation. Due to this, power transfer to specific outgoing modes
can be suppressed, resulting in completely lossless configurations. The excitation
is further examined for incoming, laterally confined wave bundles of semi-guided
waves to realize practically more relevant 3-D configurations. Additionally, a
stepwise angular spectrum method in combination with full vectorial 2-D finite
element solutions for subproblems of lower complexity to numerically simulate
the wave propagation in full 3-D planar lens-like waveguides is presented. In
the second part, the wave propagation in lithium niobate waveguide structures
is examined, which are used for quantum optical effects. On the one hand, superconducting
nanowires on titanium in-diffused lithium niobate waveguides with an additional
tapered silicon layer are used for single photon detection. The wave propagation
in these 3-D multiscale tapers is studied by introducing a unidirectional finite
element modal matching method. On the other hand, lithium niobate rib waveguides
on silicon dioxide platforms are analyzed, focusing on the nonlinear parametric
down-conversion process used for the generation of entangled photons.

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: Here we demonstrate a new, to the best of our knowledge, type of 3-dB coupler
that has an ultra-broadband operational range from 1300 to 1600 nm with low fabrication
sensitivity. The overall device size is 800 µm including in/out S-bend waveguides.
The coupler is an asymmetric non-uniform directional coupler that consists of
two tapered waveguides. One of the coupler arms is shifted by 100 µm in the propagation
direction, which results in a more wavelength-insensitive 3-dB response compared
to a standard (not shifted) coupler. Moreover, compared to a long adiabatic coupler,
we achieved a similar wavelength response at a 16-times-smaller device length.
The couplers were fabricated using the silicon nitride platform of Lionix International.
We also experimentally demonstrated an optical switch that is made by using two
of these couplers in a Mach–Zehnder interferometer configuration. According to
experimental results, this optical switch exhibits –10 dB of extinction ratio
over the 1500–1600 nm wavelength range. Our results indicate that this new type
of coupler holds great promise for various applications, including optical imaging,
telecommunications, and reconfigurable photonic processors where compact, fabrication-tolerant,
and wavelength-insensitive couplers are essential.

text: ' A process sequence enabling the large-area fabrication of nanopillar-patterned
semiconductor templates for selective-area heteroepitaxy is developed. Herein,
the nanopillar tops surrounded by a SiNx mask film serve
as nanoscale growth areas. The molecular beam epitaxial growth of InAs on such
patterned GaAs[Formula: see text]A templates is investigated by means of electron
microscopy. It is found that defect-free nanoscale InAs islands grow selectively
on the nanopillar tops at a substrate temperature of 425 °C. High-angle annular
dark-field scanning transmission electron microscopy imaging reveals that for
a growth temperature of 400 °C, the InAs islands show a tendency to form wurtzite
phase arms extending along the lateral [Formula: see text] directions from the
central zinc blende region of the islands. This is ascribed to a temporary self-catalyzed
vapor–liquid–solid growth on [Formula: see text] B facets, which leads to a kinetically
induced preference for the nucleation of the wurtzite phase driven by the local,
instantaneous V/III ratio, and to a concomitant reduction of surface energy of
the nanoscale diameter arms. '
