Read about our new work on strong optoacoustic cooling of a 50cm-long acoustic wave by 219 K from room temperature:

Abstract:

We experimentally demonstrate optoacoustic cooling via stimulated Brillouin-Mandelstam scattering in a 50 cm-long tapered photonic crystal fiber. For a 7.38 GHz acoustic…

For her work on "Optoacoustic active cooling in waveguides", PhD student Laura Blázquez Martínez received the Best Poster Prize at the Frontiers on Nanomechanical Systems Conference (FNS) 2023! Congratulations!

Postdeadline at CLEO 2023 next week! Nonreciprocal vortex conversion based on flexural acoustic phonons. Congratulations Xinglin!

Up until now, ground state cooling using optomechanical interaction is realized in cavity-configurations and especially in the regime where optical dissipation is higher than mechanical dissipation. In our group, we consider cooling schemes in continuous optomechanical systems for example optical…

Congratulations to Dr. Alexandra Popp for defending her thesis on “Quantum limited and distributed measurements of optical fiber systems”. Alexandra is a member of two groups: the Stiller Research Group and the Marquardt Research Group and we combined our efforts on quantum communications and…

Olivia Saffer from Stellenbosch University, Capetown, South Africa and Grigorii Slinkov from Lomonosov Moscow State University, Russia, joint us as PhD student and Research Associate. A warm welcome to both of you!
