Cooling a highly nonlinear fiber to 4K, we extend the lifetime of phonons and achieve the coherent optoacoustic storage of signals for almost 140 ns. This is especially interesting for optical computing with short pulse widths and low latencies, e.g. in optical neural networks. The paper can be…

In October we had the chance to go on a group retreat to Germany’s highest mountain, the Zugspitze! Besides being an absolute unique location, we had a full program around many topics, going from physics including our traditional Brillouin-Quiz to meta-topics like mental load, general lab…

Very warm welcome to Justus Nölkensmeier, Luan Sliwa and Siddarth Singh! They are all studying at FAU and joined us for their Bachelor thesis and as student helpers, respectively.

Scaling up: We demonstrate optoacoustic storage of quadrature phase-shift keying (QPKS) signals. In particular, we show the dependence of the optical phase on the phase-mismatch which can be used as an additional knob for signal processing. The paper can be found here.

At the opening of the MPZPM, we took this happy picture of us group leaders at MPL.

Linqiao Gan started her PhD with us and joins us from the Shanghai Institute of Optics and Fine Mechanics! She will continue our experimental work on orbital angular moment modes in the optical and acoustic domain.
