New, creative research ideas and innovative technology concepts often arise in everyday scientific work. However, in order to further develop these in a publicly funded project, numerous open questions must first be clarified, especially in the initial phase, e.g. regarding the fundamental technical feasibility or the evaluation of different solutions.

The "High Performance Center Photonics" - a joint initiative of the Fraunhofer IOF and the IAP/FSU Jena as well as the associated partners Leibniz HKI and IPHT and the Helmholtz Institute Jena - promotes research in important future fields of photonics and supports the transfer of innovative ideas into solutions for science, industry and society.

With the Elevator Pitches 2023, the High Performance Center once again offered researchers from the IOF and IAP the opportunity to present their innovative ideas at the Photonics Days 2023 and to win start-up funding for the further development of these ideas through the evaluation by the audience. This year, 5 innovative ideas were presented in focused, 5-minute pitches:

• Canan Gallitschke (ACP): Brain-Computer-Interface in the Lab
• Saikat Chandra Das (IOF): Optically Measuring the Material Thickness of Transparent Objects
• Daniel Lenhardt (IOF): Emotion-Driven Photonics Interface
• Johannes Kretzschmar (IAP): Gamification of Virtual Remote Experiments
• Robert Leitel (IOF): META-Lens for infrared imaging

All the projects presented were rated very positively by the audience and were thus able to win project funding totalling €40,000 for initial experimental implementations. We would like to thank all the speakers and look forward to the results of the research projects!

With the "Unternehmen Region" (engl.: Enterprise Region) program family, the Federal Ministry of Education and Research funded eight thematically open individual programs to promote research and innovation in eastern Germany from 1999 to 2022. In total, more than 500 regional innovation initiatives were supported with a total of over two billion euros. To celebrate the outstanding results of the programs and to initiate discussions on new topics for the future, Leibniz HKI as well as Fraunhofer IOF invited to a festive symposium at the Beutenberg Campus in Jena on July 20, 2023.

The program family made it possible to support two essential subject areas that have a great tradition in the Jena region in particular: optics and precision mechanics on the one hand, and infection and active ingredient research on the other. Through diverse and interdisciplinary alliances that had emerged from the "Unternehmen Region" programs, numerous new impulses could be set in these fields, which at the same time became sources of ideas for application-oriented research throughout Germany. In particular, cross-institutional programs such as the centers for innovation competence Septomics and ultraoptics, the research consortium InfectControl, the research alliance 3Dsensation, and the growth cores fo+ and Tailored Optical Fibers (TOF) formed the cornerstones for numerous new research topics and cooperation platforms.

On July 20, 2023, the Leibniz Institute for Natural Product Research and Infection Biology e. V. Hans Knöll Institute HKI and the Fraunhofer Institute for Applied Optics and Precision Engineering IOF invited to celebrate the outstanding results of the program family "Unternehmen Region" at a festive symposium. Furthermore, discussions on new future topics were initiated and ideas were discussed on how to further promote the positive further development of the innovation ecosystem Jena. Numerous guests from science, business and politics exchanged views on the successful funding formats and the diverse impulses that the programs and alliances have set in the region as well as nationwide. In addition to the speeches, highlights included a tour of the two institutes' modern research infrastructures.

The James Webb Space Telescope is the largest and most capable space telescope ever launched into space. It started its journey to the stars on December 25. The telescope is expected to provide groundbreaking insights into scientific deep space sensing and the early history of the universe - and perhaps even discover life in space. On board: high-precision mirrors manufactured at the Fraunhofer Institute for Applied Optics and Precision Engineering IOF in Jena.

For more than ten years, astronomers have been eagerly awaiting the launch of the James Webb Space Telescope. It will succeed the Hubble Space Telescope, which has been stationed in space since 1990, and will provide an even deeper and more brilliant view of the universe than its prominent predecessor.

At the latest since the Nobel Prize in Physics was awarded in 2010 for research into graphene, 2D materials have been the focus of scientific attention. This is because these materials, which consist of only one layer of atoms, offer great potential for applications in very different fields due to their low thickness and versatile properties. In combination with optical waveguides, for example, 2D materials with outstanding optical properties enable entirely new applications in the fields of sensor technology, nonlinear optics and quantum electronics. However, bringing the two components together has so far been very complex. This is because the ultra-thin layers usually had to be produced separately and then transferred to the waveguide by hand.

Jena researchers, together with Australian colleagues, have now succeeded in growing 2D materials directly on optical fibers for the first time. This significantly simplifies the production of such hybrid nanomaterials. The team reports on their findings in the research journal "Advanced Materials".

To avoid having to wire premature babies unnecessarily for medical examinations, researchers from Jena and Ilmenau have developed a technology of contactless 3D measurement. The core of the concept is an optical sensor that can measure vital parameters such as heart rate, blood oxygen content and respiratory volume by combining high-resolution 3D measurement technology and nano-optical filters. The measurement is performed without connecting the newborn to any devices or cables and at a distance of a few meters.

For their research idea, Jan Sperrhake (Friedrich Schiller University Jena) and his team members Chen Zhang (Ilmenau University of Technology) and Maria Nisser (Jena University Hospital) received the Edmund Optics Educational Award in the "Gold" category. The award, which comes with 7,000 euros in prize money, was presented to the winning team by representatives of the optics supplier on the morning of March 4, 2020 at the Abbe Center of Photonics in Jena.
