Nano & Quantum Optics

The Nano & Quantum Optics group at the Institute of Applied Physics examines fundamental effects of nanostructured materials and quantum photonic systems in close collaboration between scientists in theory, technology, and experimental characterization. In nano optics, the vectorial nature of the electro-magnetic field as well as scattering and reflection into almost every spatial direction rules the optical response of these structures. In quantum optics, the quantum properties of few photon states allow realizing applications which are relying directly on the entanglement of such states. Particularly, in our group we are able to cover the whole process chain of design, modeling, fabrication, characterization and functional evaluation of nano and quantum optical structures with the aim of realizing and using optical systems with added functionality.

Beside our strong commitment to explore the fascinating fields of nano and quantum optics, further main research directions of the group address a broad field of photonics-related topics. On the one hand, we study fundamental science phenomena such as linear and nonlinear properties of optical microresonators, photonic crystals, and spatio-temporal dynamics in discrete optical systems. On the other hand, we are strongly engaged in application-oriented research fields, where we investigate, e.g., innovative approaches in near-field microscopy, quantum imaging, nonlinear imaging and spectroscopic techniques for biological specimen, and photon management in solar cells.
