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: In this paper, the theory of phase-locking of a microwave oscillator
on the interharmonics, i.e. non-integer harmonics, of the repetition rate of the
optical pulse train of a mode-locked laser (MLL) is developed. A balanced optical
microwave phase detector (BOMPD) is implemented using a balanced Mach-Zehnder
modulator and is employed to discriminate the phase difference between the envelope
of the optical pulses and the microwave oscillator. It is shown mathematically
that the inherent nonlinear properties of BOMPD with respect to the microwave
excitation amplitude can be used for interharmonic locking. The characteristic
functions of the phase detector for interharmonic locking are derived analytically
and are compared with the measurement results. An opto-electronic phase-locked
loop (OEPLL) is demonstrated whose output frequency locks on interharmonics of
the MLL repetition rate when an appropriate modulator bias and sufficient RF amplitude
are applied. Thus, for the first time theory and experiment of reliable locking
on interharmonics of the repetition rate of a MLL are presented.

text: We demonstrate for the first time, to the best of our knowledge, reconfigurable
and real-time orthogonal time-domain detection of a high-bandwidth Nyquist signal
with a low-bandwidth silicon photonics Mach-Zehnder modulator based receiver.
As the Nyquist signal has a rectangular bandwidth, it can be multiplexed in the
wavelength domain without any guardband as a part of a Nyquist-WDM superchannel.
These superchannels can be additionally multiplexed in space and polarization.
Thus, the presented demonstration can open a new possibility for the detection
of multidimensional parallel data signals with silicon photonics. No external
pulse source is needed for the receiver, and frequency-time coherence is used
to sample the incoming Nyquist signal with orthogonal sinc-shaped Nyquist pulse
sequences. All parameters are completely tunable in the electrical domain. The
feasibility of the scheme is demonstrated through a proof-of-concept experiment
over the entire C-band (1530 nm–1560 nm), employing a 24 Gbaud Nyquist QPSK signal
due to experimental constraints on the transmitter side electronics. However,
the silicon Mach-Zehnder modulator with a 3-dB bandwidth of only 16 GHz can process
Nyquist signals of 90 GHz optical bandwidth, suggesting a possibility to detect
symbol rates up to 90 GBd in an integrated Nyquist receiver.

text: We present the design and experimental characterization of a silicon nitride
pulse interleaver based on coupled resonator optical waveguide filters. In order
to achieve a targeted free spectral range of 1.44 THz, which is large given the
reduced optical confinement of the silicon nitride platform, individual ring resonators
are designed with tapered waveguides. Its application to time-interleaved photonically-assisted
ADCs is analyzed by combining experimental characterization of the photonic integrated
circuit with a comprehensive model of the entire ADC. The impact of fundamental
signal distortion and noise sources affecting the converter is investigated and
suitable equalization techniques at the digital signal processing level are evaluated.
The novel application of a simple but powerful equalization filter in the DSP
domain allows for a significant improvement of the digitized signal SNR. An ENOB
of 5 over a 75 GHz bandwidth (150 GS/s) and an ENOB of 4.3 over a 100 GHz bandwidth
(200 GS/s) are expected to be achievable with compact and off-the-shelf single-section
semiconductor mode locked lasers, that can be further improved with lower noise
light sources.

text: Domain walls (DWs) in ferroelectric (FE) and multiferroic materials possess
an ever-growing potential as integrated functional elements, for instance in optoelectronic
nanodevices. Mandatory, however, is the profound knowledge of the local-scale
electronic and optical properties, especially at DWs that are still incompletely
characterized to date. Here, we quantify the refractive index of individual FE
DWs in periodically-poled LiNbO3 (PPLN) single crystals.
When applying polarization-sensitive optical coherence tomography (PS-OCT) at
1300 nm using circular light polarization, we are able to probe the relevant electro-optical
properties close to and at the DWs, including also their ordinary and extraordinary
contributions. When comparing to numerical calculations, we conclude that the
DW signals recorded for ordinary and extraordinary polarization stem from an increased
refractive index of at least Δn > 2·10−3 that originates
from a tiny region of < 30 nm in width. PS-OCT hence provides an extremely
valuable tool to decipher and quantify subtle changes of refractive index profiles
for both inorganic and biomedical nanomaterial systems.

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: 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.

text: High-fidelity periodic poling over long lengths is required for robust, quasi-phase-matched
second-harmonic generation using the fundamental, quasi-TE polarized waveguide
modes in a thin-film lithium niobate (TFLN) waveguide. Here, a shallow-etched
ridge waveguide is fabricated in x-cut magnesium oxide doped TFLN and is poled
accurately over 5 mm. The high fidelity of the poling is demonstrated over long
lengths using a non-destructive technique of confocal scanning second-harmonic
microscopy. We report a second-harmonic conversion efficiency of up to 939 %/W
(length-normalized conversion efficiency 3757 %/Wcm²), measured at telecommunications
wavelengths. The device demonstrates a narrow spectral linewidth (1 nm) and can
be tuned precisely with a tuning characteristic of 0.1 nm/°C, over at least 40
°C without measurable loss of efficiency.

text: Hybrid quantum information processing combines the advantages of discrete
and continues variable protocols by realizing protocols consisting of photon counting
and homodyne measurements. However, the mode structure of pulsed sources and the
properties of the detection schemes often require the use of optical filters in
order to combine both detection methods in a common experiment. This limits the
efficiency and the overall achievable squeezing of the experiment. In our work,
we use photon subtraction to implement the distillation of pulsed squeezed states
originating from a genuinely spatially and temporally single-mode parametric down-conversion
source in non-linear waveguides. Due to the distillation, we witness an improvement
of 0.17 dB from an initial squeezing value of −1.648 ± 0.002 dB, while achieving
a purity of 0.58, and confirm the non-Gaussianity of the distilled state via the
higher-order cumulants. With this, we demonstrate the source’s suitability for
scalable hybrid quantum network applications with pulsed quantum light.

text: The characterisation of loss in optical waveguides is essential in
understanding the performance of these devices and their limitations. Whilst interferometric-based
methods generally provide the best results for low-loss waveguides, they are almost
exclusively used to provide characterization in cases where the waveguide is spatially
single-mode. Here, we introduce a Fabry-Pérot-based scheme to estimate the losses
of a nonlinear (birefringent or quasi-phase matched) waveguide at a wavelength
where it is multi-mode. The method involves measuring the generated second harmonic
power as the pump wavelength is scanned over the phase matching region. Furthermore,
it is shown that this method allows one to infer the losses of different second
harmonic spatial modes by scanning the pump field over the separated phase matching
spectra. By fitting the measured phase matching spectra from different titanium
indiffused lithium niobate waveguides to the model presented in this paper, it
is shown that one can estimate the second harmonic losses of a single spatial-mode,
at wavelengths where the waveguides are spatially multi-mode.

text: We present a time-over-threshold readout technique to count the number
of activated pixels from an array of superconducting nanowire single photon detectors
(SNSPDs). This technique places no additional heatload on the cryostat, and retains
the intrinsic count rate of the time-tagger. We demonstrate proof-of-principle
operation with respect to a four-pixel device. Furthermore, we show that, given
some permissible error threshold, the number of pixels that can be reliably read
out scales linearly with the intrinsic signal-to-noise ratio of the individual
pixel response.
