We demonstrate a photonic nonlinear activation function based on stimulated Brillouin scattering. We show that it can be widely reconfigured all-optically and is frequency selective. The paper can be found here.

Half of our group went to the Workshop of OptoMechanics and Brillouin scattering (WOMBAT) in Campinas. Organized by Prof. Gustavo Wiederhecker and Prof. Thiago Alegre, it was a superbe line-up of research talks and great networking opportunity. Thank you also for letting us take part in Brazilian…

Congratulations to Laura Blázquez Martínez who won one of the best presentation awards at the workshop for optomechanics and Brillouin scattering 2024 in Campinas, Brazil!

Welcome to our new group members Benjamin Sturm and Paulina Rivera Fuentes!

Acoustic waves with a topological order unequal to 0 enable the conversion of optical orbital angular momentum modes from 1550nm to almost 1610nm. This is the first demonstration of optics interacting with stably propagating structured acoustic modes. The paper can be found here.

A team of scientists at the Max Planck Institute for the Science of Light led by Dr. Birgit Stiller has succeeded in cooling traveling sound waves in waveguides considerably further than has previously been possible using laser light. This achievement represents a significant move towards the…
