Introduction:
| | Dissipative optical solitons are highly localized nonlinear waveforms that arise as attractors of driven–dissipative propagation models. They are routinely generated in mode-locked lasers and Kerr microresonators, where they appear as ultrashort pulses that underpin a wide range of scientific and technological applications, including Nobel-Prize–winning advances in precision measurement, frequency metrology, and ultrafast science.
In many experimentally relevant regimes, lasers and resonators support multiple coexisting solitons. When these solitons remain well separated, their individual profiles are only weakly perturbed, and their interactions are governed by a small set of global soliton degrees of freedom, such as timing and phase, which are associated with spontaneously broken continuous symmetries.
Over the past decade, advances in real-time measurement techniques have enabled direct observation of this dynamics, revealing a striking diversity of phenomena, including soliton molecules and crystals, bifurcations, dynamical transitions between coherent and incoherent binding, synchronization, and chaos. While many of these effects are reproduced in numerical simulations, progress toward a unifying theoretical framework has been slow. The goal of this Special Session is to foster interaction between theory and experiment to identify the key concepts and methods that can facilitate the breakthrough needed for predictive control of complex multi-soliton states.
