The dynamic modulation of semiconductor structures using vibrations provides a powerful tool for the control of the materials properties required for novel functionalities. Surface acoustic waves (SAWs) with GHz-frequencies and micrometre-size wavelength can be generated using piezoelectric transducers fabricated with standard integrated circuit technology. Their small propagation velocity and high sensitivity to disturbances confined to a superficial region have long been exploited in electronic signal processing and sensor applications. The SAW-induced modulation of the electro-optical properties of semiconductor structures is now been used for a wide range of applications including advanced sensors, the control of chemical processes, as well as the coherent control of carriers, spins, photons, and phonons down to the single-particle level. The latter are presently been exploited for different functionalities including advanced waveguide modulators, tuneable optical resonators, and single-electron pumps and single-photon sources. |
