All-optical signal processing using dynamic Brillouin gratings

Luc Thévenaz, Sang Hoon Chin, Nikolay Primerov

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 differenti ...

Generation and application of dynamic gratings in optical fibers using stimulated Brillouin scattering

Luc Thévenaz, Nikolay Primerov

Since the invention of optical fiber cable data transmission using light has become ubiquitous in the past years. Nonlinear optical effects, which are hardly noticed in our daily life, have become crucial and highly influential for the design and performan ...

Localized and stationary dynamic gratings via stimulated Brillouin scattering with phase modulated pumps

Luc Thévenaz, Nikolay Primerov

A novel technique for the localization of stimulated Brillouin scattering (SBS) interaction is proposed, analyzed and demonstrated experimentally. The method relies on the phase modulation of two counter-propagating optical waves by a common pseudo-random ...

Variable delay using stationary and localized Brillouin dynamic gratings

Luc Thévenaz, Nikolay Primerov

Reflections from movable, dynamic acoustic gratings in polarization maintaining (PM) fibers are employed in the long variable delay of periodic, isolated pulses. The gratings are introduced by stimulated Brillouin scattering (SBS) interaction between two c ...

Sub-centimetre Spatial Resolution in Distributed Fibre Sensing, based on Dynamic Brillouin Grating in Optical Fibers

Luc Thévenaz, Sang Hoon Chin, Nikolay Primerov

Optical fibre sensors based on stimulated Brillouin scattering in optical fibers have now clearly demonstrated their excellent capability for long-range distributed strain and temperature measurements. The fibre is used as sensing element and a value for t ...

Tunable and reconfigurable multi-tap microwave photonic filter based on dynamic Brillouin gratings in fibers

Luc Thévenaz, Sang Hoon Chin, Nikolay Primerov

We propose and experimentally demonstrate new architectures to realize multi-tap microwave photonic filters, based on the generation of a single or multiple dynamic Brillouin gratings in polarization maintaining fibers. The spectral range and selectivity o ...

Recent implementations of fiber and integrated tunable microwave photonics filters

Luc Thévenaz, Nikolay Primerov

We present recent implementations of microwave photonic filters using the following two technologies: InP-based MDR (microdisk resonator) on and coupled to a nanophotonic SOI waveguide and dynamic Brillouin gratings (DBGs) in polarization maintaining fiber ...

All-optical storage and processing in optical fibers

Luc Thévenaz, Sang Hoon Chin, Andrey Denisov, Nikolay Primerov

The recent possibility to generate and read dynamic Bragg gratings in optical fibers by the interaction of multiple optical waves through stimulated Brillouin scattering has opened a new field to realize all-optical fiber-based functions. ...

Random-access distributed fiber sensing

Luc Thévenaz, Nikolay Primerov, Andrey Denisov

Optical sensing offers an attractive solution to the societal concern for prevention of natural and human-generated threats and for efficient use of natural resources. The unprecedented properties of optical fibers make them ideal for implementing a ‘nervo ...

High-resolution Brillouin fiber sensing using random phase coding of the pump and probe waves

Luc Thévenaz, Nikolay Primerov

Distributed temperature measurements with 1.2 cm resolution based on stimulated Brillouin scattering (SBS) in standard fibers are reported. High resolution is achieved by phase-coding both pump and probe waves with a high-rate, pseudo-random binary phase c ...
