Abstract

Interaction of photons with phonons has been studied in the fields of cavity optomechanics and Brillouin scattering, with promising applications in coherent light storage, frequency conversion, optomechanical sensors, narrow-linewidth lasers, electro-optic transducers, and microwave photonics [1]. Recently, hypersound generation in extremely-high-frequency range (>1 GHz) with a single gold plasmonic nanoantenna has been demonstrated [2], as well as a proof-of-concept nanoscale measurement of the viscoelastic properties of polymers [3].
