Organic photonics for biomedical research and next generation displays (Plenary Presentation)

8 April 2024 • 10:10 - 10:55 CEST | Auditorium Schweitzer, Niveau/Level 0


Joining the rich photophysics of organic light-emitting materials with the exquisite sensitivity of optical resonances to geometry and refractive index enables a plethora of devices with unusual and exciting properties. Examples from my team include biointegrated microlasers for real time sensing of cellular activity and long-term cell tracking, as well as the development of photonic implants with extreme form factors and wireless power supply that support thousands of individually addressable organic LEDs and thus allow optogenetic targeting of neurons deep in the brain with unprecedented spatial control. Very recently, by driving the interaction between excited states in organic materials and resonances in thin optical cavities into the strong coupling regime, we unlocked new tuning parameters which may play a crucial role in the next generation of TVs and computer displays to achieve even more saturated colour while retaining angle-independent emission characteristics.

Malte C. Gather is Humboldt Professor and founding director at the Centre for Nano- and Biophotonics at University of Cologne and holds a co-appointment at University of St Andrews. His research interests are at the interface of biophotonics and organic semiconductors, with particular focus on bio-implantable LEDs and laser, mechanobiology, and strong light-matter coupling. He studied physics and material sciences at RWTH Aachen University and Imperial College London and received his PhD from University of Cologne in 2008. He previously worked at University of Iceland, Harvard University, TU Dresden, and University of St Andrews.
