Photonic crystal waveguide devices: Dispersion characteristics, anomalous refraction phenomena and their potential applications. — •Remigius Zengerle — Technical University of Kaiserslautern, Chair of Electromagnetics and optical Communications, Erwin Schroedinger street 11, D-67663 Kaiserslautern

author: R. Zengerle Early own experimental investigations on one- and two-dimensional strongly corrugated optical waveguides revealed both the existence of photonic bandgaps and anomalous refraction phenomena. Today strongly one-, two- or three-dimensional periodic structures with an omnidirectional photonic bandgap are well known as No-dqphotonicNo-dq crystals. For applications in new or improved functional components used in communications we currently investigated in more detail two unique properties which may be of special interest: Chromatic dispersion and anomalous refraction phenomena. Based on our experimental results, the dispersive and anomalous refraction properties of one- and two-dimensional photonic crystal waveguides are explained both phenomenologically and by simulations using Maxwells Theory. Possible new ways for applications of semiconductor photonic bandgap devices in optical communications will also be discussed.
