Brillouin scattering is not usually considered as a mechanism that can cause cooling of a material due to the thermodynamic dominance of Stokes scattering in most practical systems. However, it has been shown in experiments on resonators that net phonon annihilation through anti-Stokes Brillouin scattering can be enabled by means of a suitable set of optical and acoustic states. The cooling of traveling phonons in a linear waveguide, on the other hand, could lead to the exciting future prospect… 

Dynamic Brillouin cooling for continuous optomechanical systems

In general, ground state cooling using optomechanical interaction is realized in the regime where optical dissipation is higher than mechanical dissipation. Here, we demonstrate that optomechanical

On-chip inter-modal Brillouin scattering

A multi-mode optomechanical waveguide is used to create stimulated Brillouin scattering between light-fields guided in distinct spatial modes of an integrated waveguide for the first time, which decouples Stokes and anti-Stokes processes to enable single-sideband amplification and dynamics that permit near-unity power conversion.

Brillouin integrated photonics

A detailed overview of Brillouin scattering in integrated waveguides and resonators is provided, covering key concepts such as the stimulation of the BrillouIn process, in which the optical field itself induces acoustic vibrations, the importance of acoustic confinement, methods for calculating and measuring Brilluin gain, and the diversity of materials platforms and geometries.

Stimulated Brillouin Scattering in integrated photonic waveguides: forces, scattering mechanisms and coupled mode analysis

Recent theoretical studies of Stimulated Brillouin Scattering (SBS) in nanoscale devices have led to an intense research effort dedicated to the demonstration and application of this nonlinearity in

Unifying Brillouin scattering and cavity optomechanics

So far, Brillouin scattering and cavity optomechanics have been mostly disconnected branches of research, although both deal with photon-phonon coupling. This begs for the development of a broader

Tailorable stimulated Brillouin scattering in nanoscale silicon waveguides

Experiments show that radiation pressures, produced by subwavelength modal confinement, yield enhancement of Brillouin nonlinearity beyond those of material non linearity alone, which paves the way towards the hybridization of silicon photonics, microelectromechanical systems and CMOS signal-processing technologies on chip.

Stimulated Raman and Brillouin scattering can be described as the interaction of several light waves with optical and acoustic-phonon waves, respectively. The coupling parameters can be derived both

Acoustic build-up in on-chip stimulated Brillouin scattering

Treating the acoustic evolution more accurately, it is found that the backward SBS gain of sub-millimetre long waveguides is significantly reduced from the value obtained by the conventional treatment because the acoustic mode requires several decay lengths to build up to its nominal value.

Giant gain enhancement in surface‐confined resonant Stimulated Brillouin Scattering

The notion that Stimulated Brillouin Scattering (SBS) is primarily defined by bulk material properties has been overturned by recent work on nanoscale waveguides. It is now understood that boundary
