Time-Domain Distributed Fiber Sensor With 1 cm Spatial Resolution Based on Brillouin Dynamic Grating

Luc Thévenaz, Kwang-Yong Song, Sang Hoon Chin, Nikolay Primerov

We demonstrate an optical time-domain distributed fiber sensor showing the highest spatial resolution ever reported based on Brillouin dynamic grating in a polarization-maintaining fiber. In our scheme, the acoustic gratings containing the information on t ...

Photonic delay line for broadband optical signals, based on dynamic grating reflectors in fibers

Luc Thévenaz, Sang Hoon Chin, Nikolay Primerov

We experimentally demonstrate that a novel type of photonic delay line based on movable dynamic grating reflectors generated in polarization maintaining fibers can provide continuously tunable signal delaying for high capacity optical data streams and wide ...

True Time Reversal through Dynamic Brillouin Gratings in Polarization Maintaining Fibers

Luc Thévenaz, Kwang-Yong Song, Sang Hoon Chin, Nikolay Primerov

A novel technique to realize true time reversal of an optical signal, using dynamic Brillouin gratings in high-birefringence fibers, is proposed. A data sequence of optical pulses with 2-ns duration was efficiently time-reversed. A numerical simulation of ...

Ultra Wide Range Tunable Delay Line Using Dynamic Grating Reflectors in Optical Fibers

Luc Thévenaz, Kwang-Yong Song, Sang Hoon Chin, Nikolay Primerov

We experimentally demonstrate a novel technique to realize a tunable delay line based on dynamic Brillouin gratings in a high birefringence fiber. A 8ns pulse signal is continuously delayed up to 184ns with minor distortion. ...

Advanced Brillouin-based distributed optical fibre sensors with sub-meter scale spatial resolution

Luc Thévenaz, Stella Foaleng Mafang, Kwang-Yong Song, Sang Hoon Chin, Nikolay Primerov

Classical configurations of Brillouin distributed optical fibre sensors show a spatial resolution limited by the phonon lifetime to 1 meter. Novel approaches can substantially overcome this limit through the prior activation of the acoustic wave. ...

Time-domain distributed sensor with 1 cm spatial resolution based on Brillouin dynamic gratings

Luc Thévenaz, Kwang-Yong Song, Sang Hoon Chin, Nikolay Primerov

We propose and experimentally demonstrate the highest-resolution BOTDA system ever reported using Brillouin dynamic grating in a polarization-maintaining fiber (PMF). Acoustic waves containing the information of local Brillouin frequency are generated by a ...
