Metamaterial control of stimulated Brillouin scattering [PDF]
Optics Letters, 2016 Using full opto-acoustic numerical simulations, we demonstrate enhancement and suppression of the SBS gain in a metamaterial comprising a subwavelength cubic array of dielectric spheres suspended in a dielectric background material. We develop a general theoretical framework and present several numerical examples using technologically important ...

Hybrid Ytterbium/Brillouin Gain Assisted Partial Mode Locking in Yb-Doped Fiber Laser
IEEE Photonics Journal, 2015 We have demonstrated experimentally and theoretically that the hybrid ytterbium/Brillouin gain can contribute to partial mode locking in the high-loss ytterbium-doped fiber laser.

All-optical signal processing of periodic signals using a Brillouin gain comb [PDF]
, 2008 The amplification of periodic signals using a Brillouin gain comb provides the opportunity to manipulate the amplitude and phase of a signal's individual spectral harmonics and, therefore, its temporal characteristics. In addition to obvious applications

Investigation of Optical Modulators in Optimized Nonlinear Compensated LTE RoF System [PDF]
, 2014 In this paper, we investigate a nonlinear compensation technique with two different architectures using direct modulation (DM) and external modulation (EM) techniques, termed as DM based frequency dithering (DMFD) and EM based frequency dithering (EMFD).

A multiplexed CW Brillouin system for precise interrogation of a sensor array made from short discrete sections of optical fibre [PDF]
, 2008 A novel configuration for precise temperature sensing in an array of optical fibre sections is reported. The sections are chosen to have different Brillouin shifts, to enable separation of scattered light signals in the frequency domain, rather than the ...

Phase-locking in cascaded stimulated Brillouin scattering
New Journal of Physics, 2016 Cascaded stimulated Brillouin scattering is a complex nonlinear optical process that results in the generation of several optical waves that are frequency shifted by an acoustic resonance frequency.
