  text: "<jats:title>Abstract</jats:title>\r\n                  <jats:p>We present
    recent progress made towards ultra-broadband photonically assisted analog-to-digital
    converters, that leverage both the low jitter of best-of-class mode-locked lasers
    as well as the capability of optics to break down broadband signals into multiple
    lower speed tributaries that can be better handled by electronics. We review in
    particular our work on both time- and frequency-domain approaches and give an
    outlook on how these architectures can be extended to include further signal processing
    tasks such as equalization. Optically triggered track-and-hold amplifiers are
    reported with an equivalent jitter below 80 fs rms in a signal frequency range
    from 20 GHz to 70 GHz. Frequency-domain architectures implementing optical arbitrary
    waveform measurement up to signal bandwidths of 610 GHz are also shown. Finally,
    an architecture allowing the deserialization and equalization of PAM4 signals
    is introduced and modeled for operation in 400 Gb/s links.</jats:p>"
