Chaotic Internal Dynamics of Dissipative Optical Soliton Molecules

When a laser cavity supports the propagation of several ultrashort pulses, these pulses can form compact bound states called soliton molecules. Soliton molecules are fascinating objects nonlinear science, presenting striking analogies with their matter molecule counterparts. The relative timing and phase between copropagating most salient internal degrees freedom molecule. pair, composed two identical constitutes chief fundamental interest. Its major allow self-oscillating molecules, which have been recurrently observed. However, despite theoretical predictions, low-dimensional chaotic dynamics soliton-pair remain elusive.
