a Schematic of the parallel optical-soliton reactors based on a mode-locked ring-fibre laser cavity. The temporal optomechanical (OM) lattice provides trapping potentials to host parallel soliton interactions, while global and individual manipulations can be applied to control the interaction. b Scanning electron micrograph (SEM) of the PCF microstructure. c The R01-like acoustic mode in the PCF core simulated using the finite-element method. The displacement is exaggerated for clarity and the normalized pressure is indicated by the colour map. d Sketch of the experimental set-up, including an optoacoustically mode-locked fibre laser based on the PCF and external controllers. SMF single-mode fibre, EDF erbium-doped fibre, WDM wavelength-division multiplexer, FPC fibre polarization controller, TD tunable delay, TA tunable attenuator, IP in-line polarizer, OC optical coupler, ISO isolator. EFL erbium-fibre laser, EOM electro-optical modulator, and PPG programmable pattern generator. See Supplementary information (SI) Section I for more details. e Schematic of controlled soliton reactions in parallel trapping potentials. The solitonic elements trapped in each reactor can be transitioned between phase-uncorrelated long-range bound states and phase-locked soliton molecules, corresponding to the synthesis and dissociation of soliton molecules. f Artistic sketch of parallel reactors that host multi-soliton complexes as matter-like reactants, with global and individual control
