Using optoacoustic neural networks to take artificial intelligence (AI) to the next level. This is the ambitious goal of the “SOUND-PC” research project for which Prof. Birgit Stiller, Leader of the Research Group “Quantum Optoacoustics” at the Max Planck Institute for the Science of Light (MPL) and…

For a wide variety of emerging quantum technologies, such as secure quantum communications and quantum computing, quantum entanglement is a prerequisite. Scientists at the Max-Planck-Institute for the Science of Light (MPL) have now demonstrated a particularly efficient way in which photons can be…

The Photonics100 list for 2025 was published recently. Among the top innovators in photonics featured in the list is Prof. Dr. Birgit Stiller. She is head of the research group ›Quantum Optoacoustics‹ at the Max Planck Institute for the Science of Light (MPL).

Our work on “High-speed coherent photonic random-access memory in long-lasting sound waves” has been published in ACS Photonics! We demonstrate coherent storage in traveling acoustic waves for over 140 nanoseconds, while keeping a Gigahertz bandwidth.

In October we had the chance to go on a group retreat to Germany’s highest mountain, the Zugspitze! Besides being an absolute unique location, we had a full program around many topics, going from physics including our traditional Brillouin-Quiz to meta-topics like mental load, general lab…

Scaling up: We demonstrate optoacoustic storage of quadrature phase-shift keying (QPKS) signals. In particular, we show the dependence of the optical phase on the phase-mismatch which can be used as an additional knob for signal processing. The paper can be found here.
