Brief
This paper presents a theoretical analysis of the existence and stability of discrete-continuous light bullets in two-dimensional fiber arrays with general coupling schemes and demonstrates their potential formation from an initial pulse.
Summary
This paper theoretically investigates spatiotemporal optical bullets (light bullets localized in both space and time) in two-dimensional fiber arrays with general coupling schemes. The authors present an analytical description and stability analysis, supported by numerical calculations, demonstrating the existence of stable light bullets in both square and hexagonal waveguide geometries. Importantly, the study also shows that these stable light bullets can form from the propagation of an initial pulse launched into a single fiber core. This research has potential implications for applications in optical communication, high-power fiber lasers, routing, and switching.
