  • Radiation pressure is not the only way to push or pull matter and drive light–matter interactions. Optomechanical devices can now be driven thermoelastically and amplification with acoustic-laser-like behaviour has been observed.

  • Electrically driven acousto-optic light modulators are limited to frequencies of a few hundred megahertz and are typically no smaller than a few micrometres. Here, the authors demonstrate gigahertz acousto-optic conversion of light polarization in a region of a few nanometres using pulsed laser stimulation of a ferroelectric.

  • The generation of strain in a material using light is of relevance for ultrasonic devices. Here, the authors observe a large, ultrafast photo-induced shear strain in BiFeO3at room temperature, suggesting promising uses of such oxides for high-frequency acoustic devices.
