text: Superconducting nanowire single-photon detectors (SNSPDs) show near
unity efficiency, low dark count rate, and short recovery time. Combining these
characteristics with temporal control of SNSPDs broadens their applications as
in active de-latching for higher dynamic range counting or temporal filtering
for pump-probe spectroscopy or LiDAR. To that end, we demonstrate active gating
of an SNSPD with a minimum off-to-on rise time of 2.4 ns and a total gate length
of 5.0 ns. We show how the rise time depends on the inductance of the detector
in combination with the control electronics. The gate window is demonstrated to
be fully and freely, electrically tunable up to 500 ns at a repetition rate of
1.0 MHz, as well as ungated, free-running operation. Control electronics to generate
the gating are mounted on the 2.3 K stage of a closed-cycle sorption cryostat,
while the detector is operated on the cold stage at 0.8 K. We show that the efficiency
and timing jitter of the detector is not altered during the on-time of the gating
window. We exploit gated operation to demonstrate a method to increase in the
photon counting dynamic range by a factor 11.2, as well as temporal filtering
of a strong pump in an emulated pump-probe experiment.

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: 'We review our results of numerical simulations of light scattering from different
systems of densely packed irregular particles. We consider spherical clusters,
thick layers and monolayers with realistic topologies and dimensions much larger
than the wavelength of light. The maximum bulk packing density of clusters is
0.5. A numerically exact solution of the electromagnetic problem is obtained using
the Discontinuous Galerkin Time Domain method and with application of high- performance
computing. We show that high packing density causes light localization in such
structures which makes an impact on the opposition phenomena: backscattering intensity
surge and negative linear polarization feature. Diffuse multiple scattering is
significantly reduced in the case of non-absorbing particles and near-field interaction
results in a percolation-like light transport determined by the topology of the
medium. With this the negative polarization feature caused by single scattering
gets enhanced if compared to lower density samples. We also confirm coherent double
scattering mechanism of negative polarization for light scattered from dense absorbing
slabs. In this case convergent result for the scattering angle polarization dependency
at backscattering can be obtained for a layer of just a few tens of particles
if they are larger than the wavelength.'

text: The third‐order susceptibility of lithium
niobate (LiNbO3) is calculated within a Berry‐phase formulation
of the dynamical polarization based on the electronic structure obtained within
density‐functional theory (DFT). Maximum values of the order of m V are calculated
for photon energies between 1.2 and 2 eV, i.e., in the lower half of the optical
bandgap of lithium niobate. Both free and bound electron (bi)polarons are found
to lead to a remarkable enhancement of the third‐order susceptibility for photon
energies below 1 eV.

text: Optical traveling wave antennas offer unique opportunities to control and
selectively guide light into a specific direction, which renders them excellent
candidates for optical communication and sensing. These applications require state-of-the-art
engineering to reach optimized functionalities such as high directivity and radiation
efficiency, low sidelobe levels, broadband and tunable capabilities, and compact
design. In this work, we report on the numerical optimization of the directivity
of optical traveling wave antennas made from low-loss dielectric materials using
full-wave numerical simulations in conjunction with the particle swarm optimization
algorithm. The antennas are composed of a reflector and a director deposited on
a glass substrate, and an emitter placed in the feed gap between them serves as
an internal source of excitation. In particular, we analyze antennas with rectangular-
and horn-shaped directors made of either hafnium dioxide or silicon. The optimized
antennas produce highly directional emissions due to the presence of two dominant
guided TE modes in the director in addition to leaky modes. These guided modes
dominate the far-field emission pattern and govern the direction of the main lobe
emission, which predominately originates from the end facet of the director. Our
work also provides a comprehensive analysis of the modes, radiation patterns,
parametric influences, and bandwidths of the antennas, which highlights their
robust nature.

text: We study a double-scattering coherent mechanism of negative polarization (NP)
near opposition that is observed for powder-like surfaces. The problem is solved
numerically for absorbing structures with irregular constituents, cubes, spheres,
and ellipsoids larger than the wavelength of incident light. Our simulations show
that double scattering between two random irregular particles shows weak NP. Adding
one more particle significantly increases the relative contribution of double
scattering which enhances NP. Simulations with regular shapes and controlled geometric
parameters show that the interference mechanism is sensitive to the geometry of
the scattering system and can also result in no polarization or even strong enhancement
of positive polarization at backscattering.

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.
