Tuesday, September 22, 2020



Wake Up & Stretching

Start a new Photonics Day with a short stretching session – relaxing and reinvigorating.



Elevator Pitches for Hot-Stuff-Award of Cluster of Excellence in Photonics

Get insights into exciting research ideas in short 2-minute presentations and vote for your favorite. The elevator pitches give scientists, especially doctoral students and PosDocs, the opportunity to present their own ideas to a general public. With the funds raised they can continue to pursue their idea.



Discussion round on the topic “Founding and spin-off as a student”

You have an idea and are considering turning it into a business? Have you discovered a gap in the market that you want to fill? Or have you achieved innovative developments in your research projects that you want to exploit? Students have to pay attention to specifics on the way to their start-up/utilization. Dr. Sebastian Händschke (from the Digital Innovation Hub Photonics) and Matthias Piontek (from the Start-up Service of the Friedrich Schiller University Jena) will tell you more about this.



Pitches Lichtwerkstatt-Makeathon

Present your innovative ideas and solutions from the Lichtwerkstatt-Makeathon.



Science and Industry Lunch Break

Meet role models from Fraunhofer IOF, Max-Planck-Gesellschaft, ZEISS, UltraFast Innovations, Excelitas, DESY, Jenoptik, and Hillos in a relaxed atmosphere. They will give you insights into different professional worlds and will be available to answer your questions.



Career Fair

Various representatives of Fraunhofer IOF, Max Planck School of Photonics, Max-Planck-Gesellschaft, ZEISS, UltraFast Innovations, Technology Recruiting Experts, Active Fiber Systems, DESY, Jenoptik, Excelitas are ready to answer your questions about job and applications. Participants of the Photonics Days 2020 will also have the opportunity to talk to representatives in private about their CVs and ask questions about their own career and applications. In addition, the Welcome-Center of Jena will answer your questions about arriving, staying and studying for foreign students in Jena.



Virtual Coffee Break



Keynote 1 – Ursula Keller

Head of Research at Institute of Quantum Electronics, ETH Zurich

Topic: Optical frequency combs from ultrafast solid-state and semiconductor lasers

Keynote AbstractA fully stabilized optical frequency comb provides equally spaced frequencies for a precise ruler in optical frequency metrology. This talk will review recent progress in single and dual comb generation from diode pumped solid-state and vertical emitting semiconductor lasers. A modelocked integrated external-cavity surface-emitting laser (MIXSEL) integrates both the gain and the saturable absorber layer within the same semiconductor wafer which simplifies the laser geometry to a linear straight cavity with excellent noise performance. In dual-comb operation, the initially unpolarized beam is split with an intracavity birefringent crystal. A dual-comb MIXSEL has been used for molecular spectroscopy without the need of any additional stabilization. Novel concepts solved the Q-switching problem for gigahertz femtosecond solid-state lasers and enabled stable dual-comb generation as well.



Award ceremony for the Applied Photonics Award

The winners of the Applied Photonics Award performed outstanding research on topics of special relevance to applied photonics in their final theses. For their achievement, they are awarded the junior prize of the Fraunhofer IOF – the Applied Photonics Award. Find out more about exciting research approaches during their presentations at the award ceremony.



Keynote 2 – Stefan Traeger

Chairman of Executive Board, JENOPTIK

Topic: Corona and the impact on the photonics industry
