WebSep 24, 2024 · Stimulated Brillouin scattering (SBS) effect is a third-order nonlinear effect, which is produced by the interaction of photons with phonons in the medium [ 1 – 3 ]. The SBS effect can be exploited to realize the conversion from optical waves (with higher frequency) to acoustic waves. WebJan 7, 2024 · Then the SBS@PMMA preform was thermally drawn into a continuous fiber with a diameter of ∼930 μm on a home-made fiber drawing tower. The composite SBS@PMMA fiber was treated by soaking in acetic acid at a temperature of 60 °C for 30 min to remove the PMMA clad. The obtained SBS fiber was rinsed with ethanol and …

Here we report demonstration of a visible light photonic integrated... For intense beams of light (e.g. laser) traveling in a medium or in a waveguide, such as an optical fiber, the variations in the electric field of the beam itself may induce acoustic vibrations in the medium via electrostriction or radiation pressure. The beam may display Brillouin scattering as a result of those vibrations, usually in the direction opposite the incoming beam, a phenomenon known as stimulated Brillouin scattering (SBS). For liquids and gases, the frequency shifts typica…
