Giant Enhancement of Stimulated Brillouin Scattering in The Sub-Wavelength Limit

Abstract

Stimulated Brillouin scattering in bulk materials and micron-scaled optical fibers has been exploited to realize coherent phonon generation and slow light as well as new light sources. What happens when the size of a light-interacting system is reduced to nanoscales? A qualitatively new, and several-orders-of-magnitude more powerful form of stimulated Brillouin scattering is shown to emerge.
