| | In this work we introduce a new class of dynamic dissipative soliton in driven passive cylindrical microresonators. The combination of modulation of the input pump with the polychromatic conical radiation tails emitted due to the third order dispersion is able to stabilise cluster soliton arrangements in which individual soliton orbit within the structure in closed trajectories.
This unexpected dynamics leads to slow soliton revivals where solitons periodically appear and disappear at fixed extraction points. This results in much longer timescales than the roundtrip time, allowing the generation of high-resolution frequency combs where the free spectral range is of several orders of magnitude smaller than the one fixed by the geometry of the cavity. This ability to control instabilities and induce nontrivial soliton motion opens new paradigms for frequency comb generation with enhanced spectral control for applications.
