Working Group Quantum Optics

Head: Prof. Dr. David Hunger

Our group is exploring the enhancement of light-matter interactions with optical microcavities in the fields of solid state quantum optics, optical sensing, microscopy, spectroscopy, and optomechanics. One of the central goals is to realize efficient light-matter interfaces at the single quantum level, and to enable novel schemes for spectroscopy and sensing. We employ and further develop fiber-based Fabry-Perot microcavities, which combine microscopic mode volumes with exceptionally high quality factors, and at the same time offer open access for a variety of samples.

Current work includes the realization of a coherent spin-photon interface for NV centers in diamond [2][7][8][9], qubit control of individual rare earth ions [6], and cavity-enhanced sensing of nanosystems in liquid environments.
