    Abstract

    For more accurate and rapid measurements of Brillouin light scattering, a technique with artificially induced acoustic phonons was proposed using a ScAlN film. The ScAlN film has a giant electromechanical coupling coefficient and can radiate coherent phonons in the sub GHz and GHz range. Making use of the induced phonons, we observed Brillouin scattering in the silica bulk sample. For efficient radiation of phonons, the ScAlN film was deposited on the side surface of the sample and reflection induced Θ angle geometry was used for Brillouin scattering measurements. The high intensity of Brillouin scattering from the induced acoustic phonons was experimentally studied.
