Abstract
Living organisms have evolved powerful strategies to control and exploit light. Marine bacteria, for example, tune their optical appearance through photonic nanostructures, while microalgae use light as an energy source and an information carrier. In this talk, I will show how such biological light-matter interactions can be harnessed for functional nanophotonics. In contrast to conventional optical technologies based on hard, non-sustainable materials, living systems offer adaptive, energy-efficient, and bio-based platforms for manipulating light. Bacterial colonies can be engineered to fine-tune their optical properties, enabling controllable light emission for applications in sensing and microlasing. Microalgal biofilms intrinsically provide adaptive pathways for optical signal processing, revealing new principles for sensing and information flow. In collaboration with various groups at the MPL, we control and exploit living matter as a platform for sustainable and adaptive optical devices.
