This is done by presenting a thorough theoretical and experimental investigation of sinusoidally modulated waveguides. In addition, this thesis comprises the first experimental realization of a parity-time-symmetric structure on this platform, as well as an extended coupled mode theory for dissipative waveguides. In this context, the existence of diffusion in ordered parity-time-symmetric systems is discussed.<eng> vorgelegt von Toni Eichelkraut GutachterInnen: Alexander Szameit (Universität Rostock, Institut für Physik) ; Holger Fehske (Universität Greifswald, Institut für Physik) ; Stefan Rotter (TU Wien, Institut für Theoretische Physik) Dissertation Universität Rostock 2019 530 535.2 530 http://purl.uni-rostock.de/rosdok/id00002662 https://doi.org/10.18453/rosdok_id00002662 https://nbn-resolving.org/urn:nbn:de:gbv:28-rosdok_id00002662-2 https://d-nb.info/1293659525/34 Light evolution in dissipative waveguide lattices--(DE-627)169727384X urn:nbn:de:gbv:28-rosdok_id00002662-2 doi: 10.18453/rosdok_id00002662 oclc: 1153128251 ppn: (DE-627)1697021778
