    assisted digital-to-analog converters (DACs) using Nyquist pulse sequences (NPSs)
    are presented and investigated. Therefore, NPSs are mathematically described and
    analyzed. Based on this, the operating principle of a precise optical Nyquist
    pulse synthesizer digital-to-analog converter (PONyDAC) is described. Possible
    architectures of PONyDAC are derived and compared in terms of performance and
    practicability. Moreover, the limits of PONyDAC systems and their superiority
    over classical electronic DACs are discussed. Furthermore, discrete building-block
    based implementations and monolithic implementations in electronic-photonic integrated
    circuits (EPICs) are presented. To enable a practicable monolithic integration,
    a shrinkage of the Mach-Zehnder modulators (MZMs) has been performed by applying
    forward-biased phase shifters (FB-PSs). These FB-PSs are analyzed and modeled
    to allow the precise and reliable design of PONyDAC systems with multiple MZMs.
    Finally, data conversion and data transmission experiments are carried out to
    demonstrate the systems functionality, quantify its performance, and prove their
    superiority over purely electronic DACs.</jats:p>"
