  abstract     = {{We demonstrate an optical arbitrary waveform measurement (OAWM) system that exploits a bank of silicon photonic (SiP) frequency-tunable coupled-resonator optical waveguide (CROW) filters for gapless spectral slicing of broadband optical signals. 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.}},

  abstract     = {{Electrical-optical signal processing has been shown to be a promising path to overcome the limitations of state-of-the-art all-electrical data converters. 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.}},

  abstract     = {{Auch in der Lehrkräftebildung in der Domäne Physik ist es Ziel, im Studium vermittelte, theoretische Kenntnisse mit berufspraktischen Anforderungen von angehenden Lehrkräften in Beziehung zu setzen. Charakteristisch für das Fach ist dabei zum einen eine eher anwendungsorientierte theoretische Position zum Zusammenhang von Theorie und Praxis. Zum anderen zeichnet es sich auch durch eine Art experimentelle Orientierung aus, die die Relationierung beider Aspekte als empirisch zu klärende Herausforderung begreift. In diesem Beitrag wird daher zunächst ein kurzer Überblick über Modelle und empirische Forschungen zum Zusammenhang zwischen theoretischem Wissen und praktischem Lehrkräftehandeln gegeben, die das Verständnis der Relationierung von Theorie und Praxis in der Didaktik der Physik prägen. Anschließend werden typische Lehr-Lern-Formate beschrieben und dabei auch jeweils die Ergebnisse begleitender Wirksamkeitsevaluationen kurz dargestellt.}},
