“…Dynamic gratings therefore add another dimension to B-OTDA sensing [14-17, 19-21, 24]: a change in strain or temperature modifies the readout probe frequency of maximum reflection, as well as the value of Ω B . In addition, dynamic gratings may provide 'movable mirrors', thereby introducing a new potential platform for all-optical variable group delay [18,25]. Dynamic gratings-based delay could be free of the delay-bandwidth product limitations that undermine the performance of so-called SBS slow-light systems [26][27][28][29][30].…”

“…The proposed method is experimentally demonstrated in the localization of dynamic SBS gratings in polarization maintaining (PM) fibers [13][14][15][16][17][18][19][20][21][22][23][24][25]. Dynamic gratings are introduced by two counter-propagating pump waves, separated in frequency by Ω B and co-polarized along one principal axis of the PM fiber.…”

“…Localized dynamic gratings have been generated using pump pulses [19,25]. However, much like B-OTDA measurements over standard fibers, the generation of short gratings is restricted by the acoustic lifetime τ.…”

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 counterpropagating optical waves by a common pseudo-random bit sequence (PRBS), these waves being spectrally detuned by the Brillouin frequency shift. The PRBS symbol duration is much shorter than the acoustic lifetime. The interference between the two modulated waves gives rise to an acoustic grating that is confined to narrow correlation peaks, as short as 1.7 cm. The separation between neighboring peaks, which is governed by the PRBS length, can be made arbitrarily long. The method is demonstrated in the generation and applications of dynamic gratings in polarization maintaining (PM) fibers. Localized and stationary acoustic gratings are induced by two phase modulated pumps that are polarized along one principal axis of the PM fiber, and interrogated by a third, readout wave which is polarized along the orthogonal axis. Using the proposed technique, we demonstrate the variable delay of 1 ns-long readout pulses by as much as 770 ns. Noise due to reflections from residual off-peak gratings and its implications on the potential variable delay of optical communication data are discussed. The method is equally applicable to the modulation of pump and probe waves in SBS over standard fibers. ©2012 Optical Society of America References and links1. R. W.

“…However, the maximum achievable time delay in all SFL systems is essentially restricted by the delay-bandwidth product [9]. Recently, a novel method to generate long variable optical delays of broadband signals has been proposed [10][11]. It makes use of stimulated Brillouin scattering (SBS) interaction between two pumps that are co-polarized along one principal axis of a polarization maintaining fiber (PMF) [12][13][14].…”

Abstract: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 of the proposed periodic filters is extensively tunable, simply by reconfiguring the positions and the number of dynamic gratings along the fiber respectively. In this paper, we present a complete analysis of three different configurations comprising a microwave photonic filter implementation: a simple notch-type Mach-Zehnder approach with a single movable dynamic grating, a multi-tap performance based on multiple dynamic gratings and finally a stationary grating configuration based on the phase modulation of two counter-propagating optical waves by a common pseudo-random bit sequence (PRBS).
