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: 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: The machine recognition of speech spoken at a distance from the microphones,
known as far-field automatic speech recognition (ASR), has received a significant
increase of attention in science and industry, which caused or was caused by an
equally significant improvement in recognition accuracy. Meanwhile it has entered
the consumer market with digital home assistants with a spoken language interface
being its most prominent application. Speech recorded at a distance is affected
by various acoustic distortions and, consequently, quite different processing
pipelines have emerged compared to ASR for close-talk speech. A signal enhancement
front-end for dereverberation, source separation and acoustic beamforming is employed
to clean up the speech, and the back-end ASR engine is robustified by multi-condition
training and adaptation. We will also describe the so-called end-to-end approach
to ASR, which is a new promising architecture that has recently been extended
to the far-field scenario. This tutorial article gives an account of the algorithms
used to enable accurate speech recognition from a distance, and it will be seen
that, although deep learning has a significant share in the technological breakthroughs,
a clever combination with traditional signal processing can lead to surprisingly
effective solutions.

text: Acoustic waves in plates have proven a viable tool for testing and material
characterisation purposes. There are a multitude of options for excitation and
detection of theses waves, such as optical and piezoelectric systems. While optical
systems, with thermoelastic excitation and interferometric detection, have the
benefit of being contactless, they usually require rather complex and expensive
experimental setups. Piezoelectric systems are more easily realised but require
direct contact with the specimen and usually have a limited bandwidth, especially
in case of piezoelectric excitation. In this work, the authors compare the properties
of piezoelectric and optical detection methods for broad-band acoustic signals.
The shape (e. g. the displacement) of a propagating plate wave is given by its
frequency and wave number, allowing to investigate correlations between mode shapes
and received signal strengths. This is aided by evaluations in normalised frequency
and wavenumber space, facilitating comparisons of different specimens. Further,
the authors explore possibilities to utilise the specific properties of the detection
methods to determine acoustic material parameters.

text: Die präzise Kenntnis der Eigenschaften verwendeter Materialien hat große Bedeutung
für den Entwurf technischer Systeme aller Art, aber auch für die Überwachung solcher
Systeme im Betrieb. Für verschiedene physikalische Eigenschaften, Betriebsbedingungen
und Materialklassen werden daher geeignete messtechnische Verfahren zur Materialcharakterisierung
benötigt. In der vorliegenden Arbeit wird ein Verfahren zur ultraschallbasierten
Charakterisierung der mechanischen Eigenschaften von homogenen und faserverstärkten
thermoplastischen Polymeren unter Berücksichtigung der Richtungsabhängigkeit vorgestellt.
Plattenförmige Probekörper werden dazu mittels Laser-Pulsen hoher Energie breitbandig
angeregt und die resultierenden akustischen Lamb-Wellen aufgezeichnet. Auf Basis
der dispersiven Eigenschaften der detektierten Wellenleitermoden werden in einem
inversen Verfahren die Parameter eines linear-elastischen Materialmodells identifiziert.
Darüber hinaus wird ein Verfahren zur vollständigen Charakterisierung der Richtungsabhängigkeit
in orthotropen Materialien wie Faserverbundwerkstoffen unter Verwendung eines
zweidimensionalen Simulationsmodells vorgestellt. Das Messverfahren wird anhand
einer Untersuchungsreihe an künstlich gealterten Polymer- und Faserverbundwerkstoffen
verifiziert und die Übertragbarkeit der Ergebnisse auf den quasistatischen Fall
betrachtet. Im Vergleich mit den Ergebnissen mechanischer Zugversuche werden die
Voraussetzungen und Einschränkungen, insbesondere durch die Annahme eines ideal-elastischen
Materialmodells, diskutiert.

text: Precise knowledge of material properties is a great concern in the design
of technical systems, and in the monitoring of such systems during operation.
Therefore, metrological processes are required for materials characterisation
with respect to specific physical properties, operational conditions and classes
of materials. In the work presented herein, a measurement procedure for the ultrasonic
characterization of mechanical properties of homogeneous and fiber-reinforced
thermoplastic polymer materials is presented, considering the different degrees
of anisotropy. For this, acoustic Lamb waves are excited in a plate-shaped specimen
using high-energy laser pulses, and then recorded.Based on the dispersive characteristics
of the detected waveguide modes, an inverse procedure is applied to identify the
parameters of a linear-elastic material model. Further, a procedure for completely
characterising the orthotropy of materials like fiber-reinforced composites using
a two-dimensional simulation model is presented. The measurement procedure is
verified by examining artificially aged homogeneous polymers and composites, also
considering the applicability of results to the quasistatic case. Comparing to
the results of corresponding mechanical tensile tests, preconditions and limitations
of the procedure are discussed, specifically regarding the assumption of an ideal-elastic
material model.
