All-optical signal processing using dynamic Brillouin gratings
The manipulation of dynamic Brillouin gratings in optical fibers is demonstrated to be an extremely flexible technique to achieve, with a single experimental setup, several all-optical signal processing functions. In particular, all-optical time differentiation, time integration and true time reversal are theoretically predicted, and then numerically and experimentally demonstrated. The techniq...
متن کاملBrillouin dynamic gratings in optical fibres for distributed sensing and advanced optical signal processing
is thesis presents results of a research on applications of Brillouin dynamic gratings – distributed reflectors that can be dynamically created in an optical fibre by two optical waves. A basic theory of stimulated Brillouin scattering (SBS) is introduced, on a level enough for understanding the processes that govern SBS. Amajor part of this thesis is dedicated to studies of distributedBrillou...
متن کاملAll-optical flip-flops based on dynamic Brillouin gratings in fibers.
A method to generate an all-optical flip-flop is proposed and experimentally demonstrated based on dynamic Brillouin gratings (DBGs) in polarization maintaining fibers. In a fiber with sufficiently uniform birefringence, this flip-flop can provide extremely long storage times and ultra-wide bandwidth. The experimental results demonstrate an all-optical flip-flop operation using phase-modulated ...

متن کاملBrillouin distributed sensing using localized and stationary dynamic gratings
In this work, we apply a recent technique for the generation of stimulated Brillouin scattering (SBS) dynamic gratings that are both localized and stationary to realize high-resolution distributed temperature sensing. The gratings generation method relies on the phase modulation of two pump waves by a common pseudo-random bit sequence (PRBS), with a symbol duration that is much shorter than the...
