In this review we address the microscopic mechanisms that are involved in the
photogeneration processes of GHz–THz coherent acoustic phonons (CAP) induced by an …

Understanding and controlling vibrations in condensed matter is emerging as an essential
necessity both at fundamental level and for the development of a broad variety of …

The functionality of phonon-based quantum devices largely depends on the efficiency of the
interaction of phonons with other excitations. For phonon frequencies above 20 GHz …

All-optical switching of the polarization of exciton polaritons is studied using a picosecond
acoustic perturbation of the exciton resonance in high-Q planar Ga As/Al As microcavities …

Spin waves are promising candidates for information carriers in advanced technology. The
interactions between spin waves and acoustic waves in magnetic nanostructures are of …

Cavity optomechanical coupling based on radiation pressure, photothermal forces and the
photoelastic effect has been investigated widely over the past few decades, including optical …

The phonon mean free path is generally inferred from the measurement of thermal
conductivity and we are still lacking precise information on this quantity. Recent advances in …

Resonators based on acoustic distributed Bragg reflectors (DBRs) were optimized to work in
the GHz–THz regime, and grown by molecular beam epitaxy. We show that in structures …

The coherent generation and detection of acoustic phonons in a superlattice embedded in
an optical microcavity is theoretically analyzed. In this optical resonator, femtosecond light …

The properties of optical to acoustic transduction of semiconductor superlattices have been
explored for several years in the sub terahertz frequency range. Using femtosecond laser …
