text: Highly directive antennas with the ability of shaping radiation patterns in
desired directions are essential for efficient on-chip optical communication with
reduced cross talk. In this paper, we design and optimize three distinct broadband
traveling-wave tantalum pentoxide antennas exhibiting highly directional characteristics.
Our antennas contain a director and reflector deposited on a glass substrate,
which are excited by a dipole emitter placed in the feed gap between the two elements.
Full-wave simulations in conjunction with global optimization provide structures
with an enhanced linear directivity as high as 119 radiating in the substrate.
The high directivity is a result of the interplay between two dominant TE modes
and the leaky modes present in the antenna director. Furthermore, these low-loss
dielectric antennas exhibit a near-unity radiation efficiency at the operational
wavelength of 780 nm and maintain a broad bandwidth. Our numerical results are
in good agreement with experimental measurements from the optimized antennas fabricated
using a two-step electron-beam lithography, revealing the highly directive nature
of our structures. We envision that our antenna designs can be conveniently adapted
to other dielectric materials and prove instrumental for inter-chip optical communications
and other on-chip applications.

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: AbstractPolarons influence decisively the
performance of lithium niobate for optical applications. In this work, the formation
of (defect) bound polarons in lithium niobate is studied by ab initio molecular
dynamics. The calculations show a broad scatter of polaron formation times. Rising
temperature increases the share of trajectories with long formation times, which
leads to an overall increase of the average formation time with temperature. However,
even at elevated temperatures, the average formation time does not exceed the
value of 100 femtoseconds, i.e., a value close to the time measured for free,
i.e., self-trapped polarons. Analyzing individual trajectories, it is found that
the time required for the structural relaxation of the polarons depends sensitively
on the excitation of the lithium niobate high-frequency phonon modes and their
phase relation.

text: We study the DC conductivity in potassium titanyl phosphate (KTiOPO4, KTP)
and its isomorphs KTiOAsO4 (KTA) and Rb1%K99%TiOPO4 (RKTP) and introduce a method
by which to reduce the overall ionic conductivity in KTP by a potassium nitrate
treatment. Furthermore, we create so-called gray tracking in KTP and investigate
the ionic conductivity in theses areas. A local unintended reduction of the ionic
conductivity is observed in the gray-tracked regions, which also induce additional
optical absorption in the material. We show that a thermal treatment in an oxygen-rich
atmosphere removes the gray tracking and brings the ionic conductivity as well
as the optical transmission back to the original level. These studies can help
to choose the best material and treatment for specific applications.

text: Online solvers for a series of standard 1-D or 2-D problems in integrated
optics will be discussed. Implemented on the basis of HTML/JavaScript/SVG with
core routines compiled from well tested C++-sources, the quasi-analytical algorithms
require a computational load that can be handled easily even by current mobile
devices. So far the series covers the 1-D guided modes of dielectric multilayer
slab waveguides and the oblique plane wave reflection from these, the modes of
rectangular channel waveguides (in an approximation of effective indices), bend
modes of curved multilayer slabs, whispering-gallery resonances (“Quasi-Normal-Modes”)
supported by circular dielectric cavities, the hybrid modes of circular multi-step-index
optical fibers, bound and leaky modes of 1-D complex multilayers, including plasmonic
surface modes, and, with restrictions, quite general rectangular scattering problems
in 2-D.

text: Many-body perturbation theory based on density-functional theory calculations
is used to determine the quasiparticle band structures and the dielectric functions
of the isomorphic ferroelectrics rubidium titanyl phosphate (RbTiOPO4) and potassium
titanyl arsenide (KTiOAsO4). Self-energy corrections of more than 2 eV are found
to widen the transport band gaps of both materials considerably to 5.3 and 5.2
eV, respectively. At the same time, both materials are characterized by strong
exciton binding energies of 1.4 and 1.5 eV, respectively. The solution of the
Bethe-Salpeter equation based on the quasiparticle energies results in onsets
of the optical absorption within the range of the measured data.

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: 'Hole polarons and defect-bound exciton polarons in lithium niobate are investigated
by means of density-functional theory, where the localization of the holes is
achieved by applying the +U approach to the oxygen 2p orbitals. We find three
principal configurations of hole polarons: (i) self-trapped holes localized at
displaced regular oxygen atoms and (ii) two other configurations bound to a lithium
vacancy either at a threefold coordinated oxygen atom above or at a two-fold coordinated
oxygen atom below the defect. The latter is the most stable and is in excellent
quantitative agreement with measured g factors from electron paramagnetic resonance.
Due to the absence of mid-gap states, none of these hole polarons can explain
the broad optical absorption centered between 2.5 and 2.8 eV that is observed
in transient absorption spectroscopy, but such states appear if a free electron
polaron is trapped at the same lithium vacancy as the bound hole polaron, resulting
in an exciton polaron. The dielectric function calculated by solving the Bethe–Salpeter
equation indeed yields an optical peak at 2.6 eV in agreement with the two-photon
experiments. The coexistence of hole and exciton polarons, which are simultaneously
created in optical excitations, thus satisfactorily explains the reported experimental
data.'
