Friedrich Schiller University Jena (FSU)

The Institute of Applied Physics of the Friedrich Schiller University Jena (FSU) is known for its developments of novel optical materials and elements – from basic to application orientated research. It offers remarkable contributions to solving issues in emerging fields like information and communication, health and medicine, environment and energy as well as process technology and optical measurement methods. For this purpose, current research topics concern function, design and production of various micro- and nano-optical elements, light propagation and nonlinear light-matter interaction in micro- and nanostructures, optical meta materials and photonic crystals. Further research fields are application spanning the dynamic range from high-power femtosecond laser pulses for material processing and ultrafast fiber lasers to the level of single- and entangled photons for applications in imaging, sensing and information processing.
The research group “Photonic Quantum Information” focuses on methods for generating and manipulating quantum states of light and their application in remote sensing, long-distance communication, and multi-partite quantum networks.

He is a first-time participant to the FET program.

Fabian Steinlechner

Fabian Steinlechner received his PhD in 2015 from ICFO - The Institute of Photonic Sciences where his doctoral research focused on the development of quantum light sources for applications in Space. As a Postdoctoral Fellow at the Institute for Quantum Optics and Quantum Information in Vienna, he contributed to the application of entangled photons in loophole-free tests of non-locality, quantum sensing, high-dimensional quantum information processing, and long-distance quantum communication in free-space and fiber links. In August 2018 he was appointed junior group leader within the Attract-Programme of the Fraunhofer Society. He currently leads the "Photonic Quantum Communication” group at Fraunhofer IOF and the “Photonic Quantum Information” group within the “Leistungszentrum Photonik” and the Abbe Center of Photonics at the Friedrich Schiller University Jena. Since 2020 FS is acting group leader of the “Active and Adaptive Optics” group at Fraunhofer IOF, working primarily on adaptive optical systems for satellite-based ranging and quantum key distribution systems in space.
