Abstract

Brillouin spectroscopy is a powerful tool for non-invasive elasticity-specific optical imaging. We report an observation of enhancements of Brillouin scattering from liquid samples in the presence of gold nanostructures. These enhancements are attributed to surface plasmons generated by nanostructures and are found to be dependent on the nanostructures' architecture (i.e. their sizes and aspect ratios). These observations suggest that plasmonic nanostructures composed of nanodisk arrays can provide a platform for practical implementation of surface-enhanced Brillouin scattering, which is capable of localizing interaction to a nanoscopic volume to facilitate high spatial resolution elasticity measurements.
