We welcome Alexander Jung who joins our optomechanics team. Alexander did his Master thesis at the Walther-Meissner-Institute in Garching, Germany and will now do his PhD with us. His goal is to increase the optomechanical coupling strength and at the same time reduce the optical lossses. towards single photon strong coupling …
A warm welcome!

We offer the following Master thesis projects in our lab during 2023/2024:

• Micro-mechanical resonators in fiber Fabry-Perot cavities
• Fabrication technologies for chip-based magnetic traps
• Design, simulation and optimization of a phononically shielded sample holder for chip-based magnetic traps
• Vibration Isolation Stage for Quantum Experiments at mK Temperature
• Superconducting resonators for macroscopic quantum experiments

If you are interested, please get in contact with us.

We welcome Lauren as a new Master thesis student in our lab. Lauren will join our research activities focused on cavity optomechanics and high-Q crystalline materials for nanomechanics.

We have realized high-Q trampoline resonators in tensile-strained InGaP with a Q of 10⁷. This is a first step towards using crystalline materials for integrated cavity optomechanics. Our work has now been published in Nano Letters, see here. Thanks for the great effort in the cleanroom and for the material growth!

We have put our most recent work on the arxiv, read it here. We demonstrate a new concept to realize an optomechanical microcavity. We unite in-plane and out-of-plane light propagation to increase the optomechanical coupling strength. Wonderful teamwork between experiment and theory!
