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!

Laser Focus World featured Birgit Stiller in a podcast interview on our vision on fabrication-free optical neural networks. It goes into detail on different versatile building blocks, that we already achieved on the road to this goal, i.e. fully optical nonlinear activation functions, coherent…

We met with the research groups Del’Haye and Fattahi for our yearly visit of Berg. As always, a lot of fun!

Enhancing the capacity of Brillouin-based storage: we demonstrate optoacoustic storage of quadrature phase-shift keying (QPKS) signals. More important and interesting for training of optical neural networks, we show the dependence of the optical phase on the phase-mismatch which can be used as an…

Very warm welcome to Faress Madhoun and Cyrus Young! Both are currently in their undergraduate studies at the universities of Ottawa and British Columbia, respectively, and joined us for research internships until summer.

The group gathered for a small get-together. Everybody brought some snacks and wine and we took the evening going through all the different options and celebrating the ERC grant we received in December last year.
