Proceedings ArticleDOI
High Spatial and Spectral Resolution Long-Range Sensing Using Brillouin Echoes
TL;DR: In this paper, the authors proposed an approach that can overcome this limit to offer spatial resolutions in the centimetre range, while preserving full measurand accuracy, and demonstrated that this approach can be achieved with a practical spatial resolution of 1 meter.
Proceedings ArticleDOI
True Time Reversal via Dynamic Brillouin Gratings in Polarization Maintaining Fibers
Sang Hoon Chin,Nikolay Primerov,Kwang Yong Song,Luc Thévenaz,Marco Santagiustina,Leonora Ursini +5 more
TL;DR: In this article, a novel technique to realize true time reversal of an optical signal, using dynamic Brillouin gratings in high-birefringence fibers, is proposed.
Proceedings ArticleDOI
Enhancing the light-matter interaction using slow light: towards the concept of dense light
TL;DR: In this article, the impact of slow light on simple molecular absorption was evaluated under either material or structural slow light propagation in the same medium and led to an entirely different response, and the experiments were designed, so that the process generating slow light and the probed light-matter interaction only present a marginal cross-effect.
Proceedings ArticleDOI
All-optical calculus based on dynamic Brillouin grating reflectors in optical fibers
TL;DR: In this paper, the authors demonstrate that all-optical signal calculus can be realized based on dynamic Brillouin gratings in optical fibers, and demonstrate that first-order differentiation can be performed for optical pulse with various waveforms.

Fiber sensing system based on a bragg grating and optical time domain reflectometry
Sang Hoon Chin,Luc Thévenaz +1 more
TL;DR: Optic fiber sensor characterized in that the sensing fiber is provided with a continuous Bragg grating covering the entire fiber length which is dedicated to sensing and along which spatially resolved measurements are performed.
