Nonlinear Light Dynamics in Multi-Core Structures
Abstract
The project has led to a number of results, including introduction of the key mathematical models governing optical field propagation in the multiple-core structures (e.g. waveguides and fibers); study of the properties of light-bullets fully localized both in space and time that can begenerated in continuous-discrete optical media such as multi-core optical fiber or waveguide arrays; localisation dynamics in a continuous discrete non-linear system. Detailed theoretical analysis is presented of the existence and stability of the discrete-continuous light bullets usinga very generic model that occurs in a number of application, study of the steady state propagation regimes, study of the modulation instability in multiple-core fibers (MCFs), investigation of the nonlinear stage of the instability and energy transfer. A numerical demonstration of a light pulse combining and pulse compression using wave collapse (self-focusing) energy localisation dynamics in a continuous-discrete nonlinear system, as implemented in a MCF using 1D and 2D core distribution designs. Largescalenumerical simulations were performed to determine the conditions of the most efficient coherent combining and compression of pulsesinjected into the considered MCFs.
