PT Unknown AU Fedder, H Oesterwind, S Wick, M Olbrich, F Michler, P Veigel, T Berroth, M Schlagmüller, M TI Characterization of electro-optical devices with low jitter single photon detectors – towards an optical sampling oscilloscope beyond 100 GHz SE ECOC PY 2018 BP 1 EP 3 DI 10.1109/ECOC.2018.8535415 DE SSPD; SNSPD; SPAD AB We showcase an optical random sampling scope that exploits single photon counting and apply it to characterize optical transceivers. We study single photon detectors with a jitter down to 40 ps. The method can be extended beyond 100 GHz. ER
