The main limitation on ENOB in purely electrical ADCs lies in the relatively high jitter of oscillators, in the order of a few tens of fs for state-of-the-art components. When compared to the extremely low jitter obtained with best-in-class Ti:sapphire mode-locked lasers (MLL), in the attosecond range, it is apparent that a mixed electrical-optical architecture could significantly improve the converters' ENOB. We model and analyze the ENOB limitations arising from optical sources in optically enabled, spectrally sliced ADCs, after discussing the system architecture and implementation details. The phase noise of the optical carrier, serving for electro-optic signal transduction, is shown not to propagate to the reconstructed digitized signal and therefore not to represent a fundamental limit. The optical phase noise of the MLL used to generate reference tones for individual slices also does not fundamentally impact the converted signal, so long as it remains correlated among all the comb lines. On the other hand, the timing jitter of the MLL, as also reflected in its RF linewidth, is fundamentally limiting the ADC performance, since it is directly mapped as jitter to the converted signal. The hybrid nature of a photonically enabled, spectrally sliced ADC implies the utilization of a number of reduced bandwidth electrical ADCs to convert parallel slices, resulting in the propagation of jitter from the electrical oscillator supplying their clock. Due to the reduced sampling rate of the electrical ADCs, as compared to the overall system, the overall noise performance of the presented architecture is substantially improved with respect to a fully electrical ADC. author: - first_name: Andrea full_name: Zazzi, Andrea last_name: Zazzi - first_name: Juliana full_name: Müller, Juliana last_name: Müller - first_name: Sergiy full_name: Gudyriev, Sergiy last_name: Gudyriev - first_name: Pablo full_name: Marin-Palomo, Pablo last_name: Marin-Palomo - first_name: Dengyang full_name: Fang, Dengyang last_name: Fang - first_name: Christoph full_name: Scheytt, Christoph id: '37144' last_name: Scheytt orcid: https://orcid.org/0000-0002-5950-6618 - first_name: Christian full_name: Koos, Christian last_name: Koos - first_name: Jeremy full_name: Witzens, Jeremy last_name: Witzens citation: ama: 'Zazzi A, Müller J, Gudyriev S, et al.

In both data converter architectures, a mode-locked laser is assumed to provide an optical comb whose lines are used to either synthesize or analyze individual spectral slices. While the optical phase noise of the central MLL line as well as of other optical carriers used in the analyzed system architectures have a minor impact on the system performance, the RF phase noise of the MLL fundamentally limits it. In particular, the corresponding jitter of the MLL pulse train is transferred almost one-to-one to the system-level timing jitter of the data converters. While MLL phase noise can in principle be tracked and removed by electronic signal processing, this results in electric oscillator phase noise replacing the MLL jitter and is not conducive in systems leveraging the ultra-low jitter of low-noise mode-locked lasers. Precise analytical models are derived and validated by detailed numerical simulations. author: - first_name: Andrea full_name: Zazzi, Andrea last_name: Zazzi - first_name: Juliana full_name: Müller, Juliana last_name: Müller - first_name: Sergiy full_name: Gudyriev, Sergiy last_name: Gudyriev - first_name: Pablo full_name: Marin-Palomo, Pablo last_name: Marin-Palomo - first_name: Dengyang full_name: Fang, Dengyang last_name: Fang - first_name: Christoph full_name: Scheytt, Christoph id: '37144' last_name: Scheytt orcid: https://orcid.org/0000-0002-5950-6618 - first_name: Christian full_name: Koos, Christian last_name: Koos - first_name: Jeremy full_name: Witzens, Jeremy last_name: Witzens citation: ama: Zazzi A, Müller J, Gudyriev S, et al.

Like in a conventional phased array system with optical carrier distribution, optical fibers are used to distribute the carrier from the basestation to the wireless frontends. However in contrast to prior concepts, we propose to use an optical IQ return path from the wireless frontends back to the basestation. Furthermore, we reuse the optical carrier signal for the IQ return path which allows to avoid local oscillator lasers in the wireless frontends and reduces the hardware effort significantly. The system concept allows to integrate all components of an optoelectronic wireless frontend in a single chip using silicon photonics technology. author: - first_name: Stephan full_name: Kruse, Stephan id: '38254' last_name: Kruse - first_name: Christian full_name: Kress, Christian id: '13256' last_name: Kress - first_name: Christoph full_name: Scheytt, Christoph id: '37144' last_name: Scheytt orcid: https://orcid.org/0000-0002-5950-6618 - first_name: Heiko G. full_name: Kurz, Heiko G. last_name: Kurz - first_name: Thomas full_name: Schneider, Thomas last_name: Schneider citation: ama: 'Kruse S, Kress C, Scheytt C, Kurz HG, Schneider T.

In this paper a concept for an OEPLL-based frequency synthesizer is presented and it is investigated how it can be used as a local oscillator (LO) for THz transceivers in order to improve the signal quality in THz wireless communications. The concept of the OEPLL is presented and it's measured phase noise is compared to the phase noise of a laboratory-grade electronic frequency synthesizer. The measured phase noise spectra of both synthesizers at 10 GHz are then used to model LO phase noise at 320 GHz. Based on models of generic zero-IF transmit and receive frontends, THz signals with different modulation formats and Baud rates are simulated at system level using the modeled LO phase noise for the two LO approaches. Finally, the results are compared. author: - first_name: Christoph full_name: Scheytt, Christoph id: '37144' last_name: Scheytt orcid: https://orcid.org/0000-0002-5950-6618 - first_name: Dominik full_name: Wrana, Dominik last_name: Wrana - first_name: Meysam full_name: Bahmanian, Meysam id: '69233' last_name: Bahmanian - first_name: Ingmar full_name: Kallfass, Ingmar last_name: Kallfass citation: ama: 'Scheytt C, Wrana D, Bahmanian M, Kallfass I.
