  bibo_abstract:
  - The growing demand for bandwidth and energy efficiency requires new solutions
    for signal detection and processing. We demonstrate a concept for high-bandwidth
    signal detection with low-speed photodetectors and electronics. The method is
    based on the parallel optical sampling of a high-bandwidth signal with sinc-pulse
    sequences provided by a Mach-Zehnder modulator. For the electronic detection and
    processing this parallel sampling enables to divide the high-bandwidth optical
    signal with the bandwidth B into N electrical signals with the baseband bandwidth
    of B/(2N) . In proof-of-concept experiments with N=3 , we present the detection
    of 24 GHz optical signals by detectors with a bandwidth of only 4 GHz. For ideal
    components, the sampling and bandwidth down-conversion does not add an excess
    error to the signals and even for the non-ideal components of our proof-of-concept
    setup, it is below 1%. Thus, the rms error for the measurement of the 24 GHz signal
    was reduced by a factor of about 3.4 and the effective number of bits were increased
    by 1.8.@eng
