Control of Elementary Excitations by Acoustic Fields

Scalability is presently a major barrier for the integration of different functionalities in opto-electronic quantum devices. Here, we demonstrated that scalable exciton systems can be realized by using surface acoustic wave (SAW) beams to controllably couple them.

The long lifetimes and their strong interaction with photons makes indirect excitons (IXs) ideal particles for applications in optoelectronics and quantum information. We show here that IX packets can be transported by surface acoustic waves (SAWs) over long (100 micrometers) distances on a...

We demonstrate the guiding of GHz surface acoustic waves on silicon chips using a CMOS-compatible waveguide technology.

We have provided experimental evidence for the Gap soliton (GS) character of polariton condensates in 2D shallow potentials. GSs in 2D potentials are qualitative different from their 1D counterparts, for example opening the way to the realization of novel topological phases. This approach is a...

The oscillating piezoelectric field of a surface acoustic wave (SAW) extends above the surface of the piezoelectric material where it propagates. In this contribution, we demonstrate that this field can be employed to remotely transport electrons and holes in GaAs nanowires deposited on top of a...
