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: 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: 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: 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: Multimode integrated interferometers have great potential for both
spectral engineering and metrological applications. However, the material dispersion
of integrated platforms constitutes an obstacle that limits the performance and
precision of such interferometers. At the same time, two-colour nonlinear interferometers
present an important tool for metrological applications, when measurements in
a certain frequency range are difficult. In this manuscript, we theoretically
developed and investigated an integrated multimode two-colour SU(1,1) interferometer
operating in a supersensitive mode. By ensuring the proper design of the integrated
platform, we suppressed the dispersion, thereby significantly increasing the visibility
of the interference pattern. The use of a continuous wave pump laser provided
the symmetry between the spectral shapes of the signal and idler photons concerning
half the pump frequency, despite different photon colours. We demonstrate that
such an interferometer overcomes the classical phase sensitivity limit for wide
parametric gain ranges, when up to 3×104 photons are generated.

text: Lithium niobate on insulator (LNOI) has a great potential for photonic integrated
circuits, providing substantial versatility in design of various integrated components.
To properly use these components in the implementation of different quantum protocols,
photons with different properties are required. In this paper, we theoretically
demonstrate a flexible source of correlated photons built on the LNOI waveguide
of a special geometry. This source is based on the parametric down-conversion
(PDC) process, in which the signal and idler photons are generated at the telecom
wavelength and have different spatial profiles and polarizations, but the same
group velocities. Distinguishability in polarizations and spatial profiles facilitates
the routing and manipulating individual photons, while the equality of their group
velocities leads to the absence of temporal walk-off between photons. We show
how the spectral properties of the generated photons and the number of their frequency
modes can be controlled depending on the pump characteristics and the waveguide
length. Finally, we discuss special regimes, in which narrowband light with strong
frequency correlations and polarization-entangled Bell states are generated at
the telecom wavelength.

text: Quantum walks function as essential means to implement quantum simulators,
allowing one to study complex and often directly inaccessible quantum processes
in controllable systems. In this contribution, the notion of a driven Gaussian
quantum walk is introduced. In contrast to typically considered quantum walks
in optical settings, we describe the operation of the walk in terms of a nonlinear
map rather than a unitary operation, e.g., by replacing a beam-splitter-type coin
with a two-mode squeezer, being a process that is controlled and driven by a pump
field. This opens previously unattainable possibilities for quantum walks that
include nonlinear elements as core components of their operation, vastly extending
their range of applications. A full framework for driven Gaussian quantum walks
is developed, including methods to dynamically characterize nonlinear, quantum,
and quantum-nonlinear effects. Moreover, driven Gaussian quantum walks are compared
with their classically interfering and linear counterparts, which are based on
classical coherence of light rather than quantum superpositions. In particular,
the generation and boost of highly multimode entanglement, squeezing, and other
quantum effects are studied over the duration of the nonlinear walk. Importantly,
we prove the quantumness of the evolution itself, regardless of the input state.
A scheme for an experimental realization is proposed. Furthermore, nonlinear properties
of driven Gaussian quantum walks are explored, such as amplification that leads
to an ever increasing number of correlated quantum particles, constituting a source
of new walkers during the walk. Therefore, a concept for quantum walks is proposed
that leads to—and even produces—directly accessible quantum phenomena, and that
renders the quantum simulation of nonlinear processes possible.

text: GaAs-(111)-nanostructures exhibiting second harmonic generation are new building
blocks in nonlinear optics. Such structures can be fabricated through epitaxial
lift-off using selective etching of Al-containing layers and subsequent transfer
to glass substrates. Herein, the selective etching of (111)B-oriented AlxGa1−xAs
sacrificial layers (10–50 nm thick) with different aluminum concentrations (x
= 0.5–1.0) in 10\% hydrofluoric acid is investigated and compared with standard
(100)-oriented structures. The thinner the sacrificial layer and the lower the
aluminum content, the lower the lateral etch rate. For both orientations, the
lateral etch rates are in the same order of magnitude, but some quantitative differences
exist. Furthermore, the epitaxial lift-off, the transfer, and the nanopatterning
of thin (111)B-oriented GaAs membranes are demonstrated. Atomic force microscopy
and high-resolution X-ray diffraction measurements reveal the high structural
quality of the transferred GaAs-(111) films.

text: Gaussian-beam-like bundles of semi-guided waves propagating in a dielectric
slab can excite modes with high-order optical angular momentum supported by a
circular fiber. We consider a multimode step-index fiber with a high-index coating,
where the waves in the slab are evanescently coupled to the modes of the fiber.
Conditions for effective resonant interaction are identified. Based on a hybrid
analytical–numerical coupled mode model, our simulations predict that substantial
fractions of the input power can be focused into waves with specific orbital angular
momentum, of excellent purity, with a clear distinction between degenerate modes
with opposite vorticity.

text: We show that narrow trenches in a high-contrast silicon-photonics slab can
act as lossless power dividers for semi-guided waves. Reflectance and transmittance
can be easily configured by selecting the trench width. At sufficiently high angles
of incidence, the devices are lossless, apart from material attenuation and scattering
due to surface roughness. We numerically simulate a series of devices within the
full 0-to-1-range of splitting ratios, for semi-guided plane wave incidence as
well as for excitation by focused Gaussian wave bundles. Straightforward cascading
of the trenches leads to concepts for 1×M-power dividers and a polarization beam
splitter.

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.

text: Uniaxial anisotropy in nonlinear birefringent crystals limits the
efficiency of nonlinear optical interactions and breaks the spatial symmetry of
light generated in the parametric down-conversion (PDC) process. Therefore, this
effect is usually undesirable and must be compensated for. However, high gain
may be used to overcome the destructive role of anisotropy in order to generate
bright two-mode correlated twin-beams. In this work, we provide a rigorous theoretical
description of the spatial properties of bright squeezed light in the presence
of strong anisotropy. We investigate a single crystal and a system of two crystals
with an air gap (corresponding to a nonlinear SU(1,1) interferometer) and demonstrate
the generation of bright correlated twin-beams in such configurations at high
gain due to anisotropy. We explore the mode structure of the generated light and
show how anisotropy, together with crystal spacing, can be used for radiation
shaping.

text: Nonlinear SU(1,1) interferometers are fruitful and promising tools
for spectral engineering and precise measurements with phase sensitivity below
the classical bound. Such interferometers have been successfully realized in bulk
and fiber-based configurations. However, rapidly developing integrated technologies
provide higher efficiencies, smaller footprints, and pave the way to quantum-enhanced
on-chip interferometry. In this work, we theoretically realised an integrated
architecture of the multimode SU(1,1) interferometer which can be applied to various
integrated platforms. The presented interferometer includes a polarization converter
between two photon sources and utilizes a continuous-wave (CW) pump. Based on
the potassium titanyl phosphate (KTP) platform, we show that this configuration
results in almost perfect destructive interference at the output and supersensitivity
regions below the classical limit. In addition, we discuss the fundamental difference
between single-mode and highly multimode SU(1,1) interferometers in the properties
of phase sensitivity and its limits. Finally, we explore how to improve the phase
sensitivity by filtering the output radiation and using different seeding states
in different modes with various detection strategies.

text: A dielectric step-index optical fiber with tube-like profile is considered,
being positioned with a small gap on top of a dielectric slab waveguide. We propose
a 2.5-D hybrid analytical/numerical coupled mode model for the evanescent excitation
of the tube through semi-guided waves propagating in the slab at oblique angles.
The model combines the directional polarized modes supported by the slab with
analytic solutions for the TE-, TM-, and orbital-angular-momentum (OAM) modes
of the tube-shaped fiber. Implementational details of the scheme are discussed,
complemented by finite-element simulations for verification purposes. Our results
include configurations with resonant in-fiber excitation of OAM modes with large
orbital angular momentum and strong field enhancement.

text: A stepwise angular spectrum method (SASM) for curved interfaces is presented
to calculate the wave propagation in planar lens-like integrated optical structures
based on photonic slab waveguides. The method is derived and illustrated for an
effective 2D setup first and then for 3D slab waveguide lenses. We employ slab
waveguides of different thicknesses connected by curved surfaces to realize a
lens-like structure. To simulate the wave propagation in 3D including reflection
and scattering losses, the stepwise angular spectrum method is combined with full
vectorial finite element computations for subproblems with lower complexity. Our
SASM results show excellent agreement with rigorous numerical simulations of the
full structures with a substantially lower computational effort and can be utilized
for the simulation-based design and optimization of complex and large scale setups.
