Congratulations to Steven Becker on receiving two outstanding research awards in 2025!

In October, Steven received a STAEDTLER Foundation Doctoral Award, which honors outstanding doctoral research at FAU Erlangen-Nürnberg. He was recognized for his thesis on optoacoustics for photonic machine…

Article in the journal “Photonic Integrated Circuits” on our groups work: we explain how the rapid growth of artificial intelligence is driving demand for new technologies that enable faster data processing and lower energy consumption. One promising approach is optical neuromorphic computing. In…

We experimentally show Brillouin-enhanced four-wave mixing for optical chiral states in twisted photonic crystal fiber, demonstrating topology-selective cross-frequency information transfer that occurs only when pump and probe have opposite circular polarization. The paper can be found here.

We experimentally demonstrate strong coupling between optical fields and travelling phonons in a waveguide at 4 K without the need of a cavity. To measure an avoided crossing a novel measurement technique is used. The paper can be found here.

Using intervortex FSBS in a twisted PCF we optically excite chiral flexural phonons and demonstrate phonon-mediated frequency conversion between optical vortex modes. The paper can be found here.

The research groups Del’Haye, Fattahi, Kunst and Stiller came together for a group retreat in the castle of the Max-Planck-Society at the Tegernsee. We had a week full of seminars, invited talks, long discussions, some hiking and a lot of fun connecting across different research groups and topics!
