Suppression of stimulated Brillouin scattering in composite media

Abstract

Overcoming stimulated Brillouin scattering (SBS) is a major challenge in optical telecommunications networks and in fiber lasers. We evaluate the SBS gain coefficient for an all-dielectric composite material comprising a cubic, subwavelength array of spheres in a uniform background. We demonstrate total SBS suppression in fused silica using GaAs spheres.
