Overview

Master's Thesis from the year 2001 in the subject Electrotechnology, grade: with distinction, City University London, 50 entries in the bibliography, language: English, abstract: Bragg gratings are important devices for both optical communications and sensing. These devices are used to design very narrow band optical filters, which can be used in wavelength division multiplexing (WDM). It is also perceived that Bragg gratings will be used to compensate the dispersion in modern fibre optic telecommunication networks. Semiconductor gratings are usually integrated into lasers to control the operating wavelength. City University Photonic Modelling Group is a world leading research group on the use of rigorous numerical techniques to design and optimise advanced photonic devices for optical communications. The research group has already achieved results on hypothetical one-dimensional (1-D) and realistic two-dimensional (2-D) structures. In this project a combination of three numerical methods has been used, all of which are rigorous, to simulate realistic three-dimensional (3-D) structures in semiconductor waveguides. The combination of these three accurate methods, the finite element method (FEM), the least squares boundary residual (LSBR) method and the transfer matrix method (TMM) turned out to be superior to the widely used coupled mode theory (CMT). The numerical study of different Bragg gratings shows interesting dependencies of the characteristics of the gratings on the different design parameters. The work was carried out for different mesh distributions, different numbers of mesh divisions and different computational parameters. Another focus of the work was on the stability of the transmission and reflection coefficients obtained from the LSBR program. Furthermore the effect of inaccuracy occurring during the fabrication process has been studied. The results of this work have been compared to results found by other groups and fellows. We can say that this proj

Author Information

Stephan Pachnicke wurde 1977 in Dortmund geboren. Von 2000-2001 absolvierte er ein Masterstudium in Information Engineering an der City University, London, Grossbritannien. Sein Studium der Elektrotechnik an der TU Dortmund schloss er 2002 mit dem Grad Dipl.-Ing. ab. 2005 wurde er zum Dr.-Ing. der Elektrotechnik promoviert - ebenfalls an der TU Dortmund. Im Jahr 2005 beendete er ausserdem ein Dipl.-Wirt.-Ing. Studium an der FernUniversitat, Hagen. Seine Habilitation wurde ihm im Januar 2012 verliehen fur Forschungsarbeiten uber Optische UEbertragungsnetze . Gleichzeitig wurde er zum Privatdozent der TU Dortmund ernannt. Von 2007 bis 2011 arbeitete er als Oberingenieur am Lehrstuhl fur Hochfrequenztechnik, TU Dortmund. Anschliessend war er bei der Firma ADVA Optical Networking SE in der Abteilung Advanced Technology (CTO Office) beschaftigt und leitete u.a. EU-finanzierte Forschungsprojekte zu optischen Zugangsnetzten der nachsten Generation. Ausserdem erforschte er Konzepte fur die Konvergenz von Fest- und Mobilfunknetzen sowie Datenzentren der nachsten Generation. Seit 2016 ist er Professor an der Christian-Albrechts-Universitat zu Kiel und leitet den Lehrstuhl fur Nachrichtenubertragungstechnik. Gleichzeitig ist er Direktor des Instituts fur Elektrotechnik und Informationstechnik. Er ist Autor bzw. Ko-Autor von mehr als 100 wissenschaftlichen Veroeffentlichungen, darunter 5 Bucher und 19 Zeitschriftenbeitrage. Stephan Pachnicke erhielt verschiedene Auszeichnungen fur seine wissenschaftliche Arbeit darunter den ITG-Preis 2012 des VDE, den Dissertationspreis 2006 der TU Dortmund sowie den VDE Preis Rhein/Ruhr 2002. Er ist Mitglied des VDE/ITG und Senior Member des IEEE.
