Welcome to the website of the Birgit Stiller Research Group

We are an independent Max Planck Research Group, centrally funded by the Max Planck Society. We are experimentalists and our main topics evolve around quantum signal processing and optical computing. Our focus is on light-sound interactions. We use our knowledge spanning from nonlinear optics to quantum communications and from fiber optics to integrated photonics.

The physics of optical waves interacting with acoustic or mechanic vibrations is fascinating because it links two very different domains in terms of frequency, velocity, dissipation and other properties. We explore the interaction experimentally at the classical and quantum level with suitably engineered microstructured fibres and nanowaveguides to manipulate, in this way, light states. Finally, we aim at using the interaction of optical and mechanical waves for applications in quantum technologies and optical neural networks.

Our current research projects focus on the following topics:

Quantum optoacoustic interactions
Photonic-phononic storage
Optoacoustic signal processing for optical neural networks
Twist and sound: interaction of structured light and structured sound
Thermodynamics and acoustics
Magnon-phonon-photon interactions
