Abstract

This research explores the complex dynamics of a synthetic optogenetic oscillator, termed the "optoscillator," in *Escherichia coli*. By applying periodic light pulses, the researchers systematically investigated the resulting spatial ring patterns under various light conditions. Combining experimental data with mathematical modeling, they demonstrated the generation of complex dynamics, including synchronization, resonance, sub-harmonic resonance, period doubling, and a chaotic regime. The study highlights the intricate spatiotemporal patterns accessible via synthetic oscillators and their potential for uncovering fundamental principles of biological oscillations.
