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. 2022 eng 1943-0655 10.1109/JPHOT.2022.3149389 14 https://ieeexplore.ieee.org/document/9707836?source=authoralert Meier, Janosch, et al. “High-Bandwidth Arbitrary Signal Detection Using Low-Speed Electronics.” <i>IEEE Photonics Journal</i>, vol. 14, 2022, doi:<a href="https://doi.org/10.1109/JPHOT.2022.3149389">10.1109/JPHOT.2022.3149389</a>.
