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.</jats:p>","lang":"eng"}],"publication":"Optics Express","language":[{"iso":"eng"}],"year":"2022","issue":"8","title":"Reconfigurable and real-time high-bandwidth Nyquist signal detection with low-bandwidth in silicon photonics","date_created":"2022-12-06T10:59:03Z","publisher":"Optica Publishing Group"},{"date_updated":"2025-07-02T12:20:13Z","publisher":"Optica Publishing Group","date_created":"2022-12-06T11:00:27Z","author":[{"full_name":"Misra, Arijit","last_name":"Misra","first_name":"Arijit"},{"last_name":"Singh","full_name":"Singh, Karanveer","first_name":"Karanveer"},{"full_name":"Meier, Janosch","last_name":"Meier","first_name":"Janosch"},{"full_name":"Kress, Christian","id":"13256","last_name":"Kress","orcid":"0000-0002-4403-2237","first_name":"Christian"},{"full_name":"Schwabe, Tobias","id":"39217","last_name":"Schwabe","first_name":"Tobias"},{"first_name":"Stefan","full_name":"Preussler, Stefan","last_name":"Preussler"},{"first_name":"J.

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.","lang":"eng"}]},{"year":"2022","issue":"10","title":"Noise Processes and Nonlinear Mechanisms in Optoelectronic Phase-Locked Loop Using a Balanced Optical Microwave Phase Detector","publisher":"Institute of Electrical and Electronics Engineers (IEEE)","date_created":"2022-12-06T11:05:28Z","publication":"IEEE Transactions on Microwave Theory and Techniques","language":[{"iso":"eng"}],"intvolume":"        70","page":"4422-4435","citation":{"ieee":"M.

However, their role in virtual prototyping and the correlation to later steps in the design process need further investigation. We introduce a metric for RISC-V instruction and register coverage for binary software. The metric measures if RISC-V instruction types are executed and if GPRs, CSRs, and FPRs are accessed. The analysis is applied by the means of a virtual prototype which is based on an abstract instruction and register model with direct correspondence to their bit level representation. In this context, we analyzed three different openly available test suites: the RISC-V architectural testing framework, the RISC-V unit tests, and programs which are automatically generated by the RISC-V Torture test generator. We discuss their tradeoffs and show that by combining them to a unified test suite we can arrive at a 100% GPR and FPR register coverage and a 98.7% instruction type coverage.","lang":"eng"}]},{"status":"public","abstract":[{"text":"Die Werkzeugdemonstration des QEMU Timing Analyzers (QTA) stellt eine Erweiterung des quelloffenen CPU Emulators QEMU zur Simulation von Softwareprogrammen und deren Worst-Case Zeitverhaltens vor, das durch eine statische Zeitanalyse vorher aus dem Softwareprogramm extrahiert wurde.

Im Preprocessing des aiT-Reports wird daraufhin ein WCET-annotierter Kontrollflussgraph erzeugt.

Furthermore, design, simulation, and measurement results of an ultra-broadband charge sampler IC in SiGe BiCMOS technology are presented. The charge sampler IC achieves a 1dB bandwidth of 70 GHz.

All the parameters such as bandwidth and channel selection are completely tunable in the electrical domain. The feasibility of this scheme is demonstrated through a demultiplexing experiment over the entire C-band (1530 nm - 1550 nm), employing 24 Gbaud Nyquist QAM signals due to experimental constraints on the transmitter side. However, the silicon Mach-Zehnder modulator with a 3-dB bandwidth of only 16 GHz can demultiplex Nyquist pulses of 90 GHz optical bandwidth suggesting a possibility to reach symbol rates up to 90 GBd in an integrated Nyquist transceiver.
