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.

Einem Team von Wissenschaftler*innen des Max-Planck-Instituts für die Physik des Lichts unter der Leitung von Dr. Birgit Stiller ist es gelungen, wandernde Schallwellen in Wellenleitern wesentlich stärker abzukühlen, als dies bisher mit Laserlicht möglich war. Damit sind sie dem Ziel, den…
