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."}],"publication":"Optics Express","language":[{"iso":"eng"}]},{"publication_identifier":{"issn":["0733-8724","1558-2213"]},"publication_status":"published","year":"2021","page":"1-1","citation":{"apa":"Fang, D., Zazzi, A., Müller, J., Dray, D., Fullner, C., Marin-Palomo, P., Tabatabaei Mashayekh, A., Dipta Das, A., Weizel, M., Gudyriev, S., Freude, W., Randel, S., Scheytt, J.

The spectral slices are coherently detected using a frequency comb as a multi-wavelength local oscillator (LO) and stitched together by digital signal processing (DSP). For high-quality signal reconstruction, we have implemented a maximum-ratio combining (MRC) technique based on precise calibration of the complex-valued opto-electronic transfer functions of all detection paths. In a proof-of-concept experiment, we demonstrate the viability of the scheme by implementing a four-channel system that offers an overall detection bandwidth of 140 GHz. Exploiting a femtosecond laser with precisely known pulse shape for calibration along with dynamic amplitude and phase estimation, we reconstruct 100 GBd QPSK, 16QAM and 64QAM optical data signals. The reconstructed signals show improved quality compared to that obtained with a single high-speed intradyne receiver, while the electronic bandwidth requirements of the individual coherent receivers are greatly reduced."}],"status":"public","_id":"29209","project":[{"name":"SPP 2111; TP: Ultrabreitbandiger Photonisch-Elektronischer Analog-Digital-Wandler (PACE) - Phase 2","_id":"303"}],"department":[{"_id":"58"},{"_id":"230"}],"user_id":"44271","keyword":["Atomic and Molecular Physics","and Optics"],"language":[{"iso":"eng"}]},{"publication_identifier":{"issn":["2644-1349"]},"publication_status":"published","year":"2021","intvolume":"         1","page":"209-221","citation":{"ieee":"A.

In addition to ultra-broadband signal processing, it allows leveraging ultra-low jitter mode-locked lasers and thus increasing the aperture jitter limited effective number of bits at high analog signal frequencies. In this paper, we review our recent progress towards optically enabled time- and frequency-interleaved analog-to-digital converters, as well as their monolithic integration in electronic-photonic integrated circuits. For signal frequencies up to 65 GHz, an optoelectronic track-and-hold amplifier based on the source-emitter-follower architecture is shown as a power efficient approach in optically enabled BiCMOS technology. At higher signal frequencies, integrated photonic filters enable signal slicing in the frequency domain and further scaling of the conversion bandwidth, with the reconstruction of a 140 GHz optical signal being shown. We further show how such optically enabled data converter architectures can be applied to a nonlinear Fourier transform based integrated transceiver in particular and discuss their applicability to broadband optical links in general."}],"status":"public","_id":"29211","project":[{"name":"SPP 2111; TP: Ultrabreitbandiger Photonisch-Elektronischer Analog-Digital-Wandler (PACE) - Phase 2","_id":"303"}],"department":[{"_id":"58"},{"_id":"230"}],"user_id":"44271","language":[{"iso":"eng"}]},{"publication_identifier":{"isbn":["978-1-943580-86-6"]},"citation":{"ieee":"D.
