The project’s goal is to develop innovative strategies using the nonlinear complexity of light waves in optical fibers. We will explore various nonlinear effects and the spatial, temporal, and spectral freedoms of multimode fibers to develop new light sources and multidimensional light control techniques. Both single-mode and multimode fibers will be considered. Our main objective is to advance the understanding of spatiotemporal mode-locking and the potential of multimode fiber laser technology, aiming to discover novel regimes of multiple spatiotemporal dissipative solitons and soliton molecules.

Managing the laser system’s complexity to achieve desired optical waveforms is a primary challenge. Machine learning and optimization procedures offer promising solutions for this. We propose using artificial intelligence to explore the controllability of novel dynamics in multimode fiber lasers, an area with significant unexplored potential.
