In this work we implement this method for the first time. Our realisation with eight detectors gives access to field moments up to fourth order. We use a laser direct written waveguide structures to implement the beam splitter cascade, and we use a photodiode array for multi-beam detection. The set-up is successfully verified with squeezed- and coherent states.<eng> Open Access Urheberrechtsschutz 1.0 vorgelegt von Milena Gödecke GutachterInnen: Boris Hage (Universität Rostock, Institut für Physik) ; Janik Wolters (Deutsches Zentrum für Luft und Raumfahrt e.V., Institut für Optische Sensorsysteme) Dissertation Universität Rostock 2025 530 https://purl.uni-rostock.de/rosdok/id00005556 Quantum optical measurement of arbitrary fourth-order field moments via balanced homodyne correlation--(DE-627)1971949574 urn:nbn:de:gbv:28-rosdok_id00005556-5 doi: 10.18453/rosdok_id00005556 oclc: 1593096774 ppn: (DE-627)1971949264
