"Interaction of SBS Gain and Losses and their Applications"

Thomas Schneider, TU Braunschweig (Alemania)


Since the stimulated Brillouin scattering is an interaction between counter-propagating optical waves mediated by an acoustical wave, the bandwidth of the interaction depends on the lifetime of the acoustical phonons. This lifetime will be changed by environmental conditions like temperature and strain, making the SBS in optical fibers an ideal effect for distributed sensors. However, there are several methods to reduce the bandwidth of SBS by one order of magnitude and possibly even further. This reduced bandwidth has many possible applications in the fields of spectroscopy, microwave photonics and optical signal processing.
In the talk the methods for reducing the SBS bandwidth will be presented and the influence of this bandwidth reduction on the phonon lifetime will be discussed. Additionally, applications of reduced bandwidth SBS like Ultra-high resolution spectroscopy, Quasi-Light storage, noise-free filters and the potential of the method for distributed sensors will be shown.

Thomas Schneider received the diploma degree in electrical engineering from the Humboldt Universität zu Berlin, Germany, in 1995, and the Ph.D. degree in physics from the Brandenburgische Technische Universität Cottbus, Germany in 2000. From 2000 to 2013 he was a Professor for high frequency technology at the Hochschule für Telekommunikation (HfT) in Leipzig, Germany, where he founded and headed the Institut für Hochfrequenztechnik. Since 2013 he has been with the Technische Universität Braunschweig. Dr. Schneider was a guest professor at the Swiss Federal Institute of Technology (EPFL), Lausanne, Switzerland, a guest scientist at the Deutsche Telekom Innovation Laboratories and at the Heinrich Hertz Institute, Berlin. His current research interests include applications of stimulated Brillouin scattering, optical signal processing and integrated silicon photonics. Dr. Schneider is the author and co-author of 4 books, more than 160 publications and 30 patents or patent applications.
