2020/07 Laura successfully completes her M.Sc. thesis on the tuning of nanophotonic resonators before moving on to ICFO for her PhD. Congratulations!

2020/06: We finish our first publication on the Fabry-Perot project, in which we show that the lifetime of erbium dopants can be reduced 59-fold, while maintinging the outstanding optical coherence properties of erbium in bulk crystalline hosts. That's a main enabling step for our future work on quantum interfaces. Details can be found in: https://arxiv.org/abs/2006.14229

2020/06: Johannes successfully completed his M.Sc. thesis. Congratulations! He will continue as a PhD student working on nanophotonic spin-photon interfaces.

2020/05: We finish the work on our first publications: In http://arxiv.org/abs/2005.08822, we investigate to which extent the interactions in erbium-doped crystals can be decoupled. In http://arxiv.org/abs/2005.01775, we observe narrow fluorescence from erbium-implanted silicon.

2020/05 Two new PhD students start on the silicon nanophotonics project: After completing his M.Sc. thesis, Florian Burger will continue to explore Purcell-enhanced erbium emission. In addition, Stephan Rinner joins the group to investigate erbium ensembles for on-chip quantum memories. Welcome!

2020/04 Alexander will continue his work on the Fabry-Perot project as a PhD student. Welcome back!

2020/02 Daniel Repp and Alexander Ulanowski completed their M.Sc. theses on the stabilization of a laser to a fiber ring resonator and the stabilization of cryogenic Fabry-Perot resonators, respectively. Congratulations!
