Signal processing and sensing based on dynamic Brillouin gratings in optical fibers.

Dynamic Brillouin gratings (DBGs) in polarization maintaining fibers (PMFs) have been demonstrated to be a powerfull technique to enhance the performance of Brillouin fiber sensors and to obtain unconventional signal processing and delay lines. The project aim is to extend the range of possible applications of this technique both in sensing and in signal processing. To this purpose both theoretical and experimental activities will be performed and applications also sought.
