text: We present a miniaturized pulse shaping device that creates an arbitrary dispersion
through the interaction of multiple metasurfaces on less than 2 mm3
volume. For this, a metalens and a grating-metasurface between two silver mirrors
are fabricated. The grating contains further phase information to achieve the
device's pulse shaping functionality.

text: We demonstrate the numerical and experimental realization of optimized optical
traveling-wave antennas made of low-loss dielectric materials. These antennas
exhibit highly directive radiation patterns and our studies reveal that this nature
comes from two dominant guided TE modes excited in the waveguide-like director
of the antenna, in addition to the leaky modes. The optimized antennas possess
a broadband nature and have a nearunity radiation efficiency at an operational
wavelength of 780 nm. Compared to the previously studied plasmonic antennas for
photon emission, our all-dielectric approach demonstrates a new class of highly
directional, low-loss, and broadband optical antennas.

text: Geometric-phase dielectric meta-lenses made of silicon with high numerical
aperture and short focal lengths are fabricated and characterised. For circularly
polarised light, the same meta-lens can act as a converging or diverging lens,
depending on the handedness of the circular polarisation. This effect enables
application for optical tweezers that trap or release µm-size polymer beads floating
in a microfluidic channel on demand. An electrically addressable polarisation
converter based on liquid crystals may be used to switch between the two states
of polarisation, at which the light transmitted through the meta-lens is focused
(trapping) or defocussed (releasing), respectively.

text: AbstractThe biexciton‐exciton emission cascade
commonly used in quantum‐dot systems to generate polarization entanglement yields
photons with intrinsically limited indistinguishability. In the present work,
it focuses on the generation of pairs of photons with high degrees of polarization
entanglement and simultaneously high indistinguishability. It achieves this goal
by selectively reducing the biexciton lifetime with an optical resonator. It demonstrates
that a suitably tailored circular Bragg reflector fulfills the requirements of
sufficient selective Purcell enhancement of biexciton emission paired with spectrally
broad photon extraction and twofold degenerate optical modes. The in‐depth theoretical
study combines (i) the optimization of realistic photonic structures solving Maxwell's
equations from which model parameters are extracted as input for (ii) microscopic
simulations of quantum‐dot cavity excitation dynamics with full access to photon
properties. It reports non‐trivial dependencies on system parameters and use the
predictive power of the combined theoretical approach to determine the optimal
range of Purcell enhancement that maximizes indistinguishability and entanglement
to near unity values, here specifically for the telecom C‐band at 1550 nm.

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.
