| Popis: | Emergent phenomena are ubiquitous in nature and refer to spatial, temporal, or spatiotemporal pattern formation in complex nonlinear systems driven out of equilibrium that is not contained in the microscopic descriptions at the single-particle level. Examples range from novel phases of matter in both quantum and classical many-body systems, to galaxy formation or neural dynamics. Two characteristic phenomena are length scales that exceed the characteristic interaction length and spontaneous symmetry breaking. Recent advances in integrated photonics indicate that the study of emergent phenomena is possible in complex coupled nonlinear optical systems. Here we demonstrate that out-of-equilibrium driving of a strongly coupled ("dimer") pair of photonic integrated Kerr microresonators, which at the "single-particle" (i.e. individual resonator) level generate well understood dissipative Kerr solitons, exhibit emergent nonlinear phenomena. By exploring the dimer phase diagram, we find unexpected and therefore unpredicted regimes of soliton hopping, spontaneous symmetry breaking, and periodically emerging (in)commensurate dispersive waves. These phenomena are not included in the single-particle description and related to the parametric frequency conversion between hybridized supermodes. Moreover, by controlling supermode hybridization electrically, we achieve wide tunability of spectral interference patterns between dimer solitons and dispersive waves. Our findings provide the first critical step towards the study of emergent nonlinear phenomena in soliton networks and multimode lattices. 19 pages, 12 figures |
