“…Numerical simulation. To provide insight into SMC switching in the 2-μm mode-locked fiber laser, the numerical simulations were executed based on the lumped propagation model, where each cavity component is modeled by a separate equation 43,44 . The gain fiber modeling includes gain saturation, bandwidth limitation, and longitudinal dependence of saturation, quantities depending on the pump power P p .…”

Dissipative optical solitons of particle-like structures can form soliton molecules with striking molecule-like interactions. However, the experimental investigation of soliton molecules in ultrafast lasers is still largely confined to bound states of only two solitons and is far from being explored for soliton molecular complexes. Here, the reconfigurable switching of soliton molecular complexes originating from the binding of two soliton-pair molecules was demonstrated around 2 μm, simultaneously opening an emerging window in the longer wavelength. The periodic switching of soliton molecules with dual-stability can be resolved. Moreover, the single and multiple successively switching of soliton molecules can be triggered by the collision of drifting soliton or control over saturable absorption parameters. Further, the consecutive reversible switching with high fidelity is verified in soliton molecules with periodic pump modulation. These results unveil the dynamical soliton interaction and motivate potential applications in ultrafast spectroscopy, information encoding, and computations.

“…Recently, real-time spectral measurements technology, such as the time-stretched dispersion Fourier transform (TS-DFT), maps the optical spectra of solitons into temporal waveforms, which makes the observation of the ultrafast soliton dynamics become possible [7][8][9][10][11][12][13][14][15][16] . With the help of the TS-DFT, phenomena such as soliton molecular 17,18 , breathing soliton dynamics 19 , soliton rain 20,21 and rogue waves 22 have been successfully observed in real time.…”

Recent advance of real-time spectral measurements offers a promising route for revealing the underlying mechanisms of transient phenomena, and successfully provides direct experimental evidence for soliton-related theoretical predictions. However, as current real-time spectrum measurement focuses on the single-port observation of laser, the continuous evolution intracavitary process with short duration cannot be fully and truly characterized. To alleviate this restriction, we present a new conceptual approach for the intracavitary process, where spectra from multi-ports of a mode-locked fiber laser are collected in time division multiplexed sequence to realize synchronous real-time observation. The sinusoidal evolution of spectral beating process caused by the non-equilibrium state between intracavitary nonlinear devices is clearly observed and matched well with the simulation. Furthermore, the intracavitary evolutions of Kelly sidebands and peaks induced by self-phase modulation are obvious asynchronous with the soliton. This work may open up possibilities for real-time observation of various intracavitary nonlinear dynamics in photonic systems.

“…Typically, when the pump power is augmented, the MPI leads to an increased number of intracavity pulses. Therefore, crossing the MPI with subsequent complex bifurcations leads to a virtually unlimited landscape of complex and chaotic ultrafast multi-pulse dynamics [30][31][32][33][34]. The interaction between dissipative solitons is also known to lead to the spontaneous formation of compact bound states, also known as dissipative soliton molecules, since they display striking analogies with their matter molecule counterparts [13].…”

When a laser cavity supports the propagation of several ultrashort pulses, these pulses interact and can form compact bound states called soliton molecules. Soliton molecules are fascinating objects of nonlinear science, which present striking analogies with their matter molecules counterparts. The soliton pair, composed of two identical pulses, constitutes the chief soliton molecule of fundamental interest. The relative timing and phase between the two propagating pulses are the most salient internal degrees of freedom of the soliton molecule. These two internal degrees of freedom allow self-oscillating soliton molecules, which have indeed been repeatedly observed, whereas the lowdimensional chaotic dynamics of a soliton-pair molecule remains elusive, noting that it would require at least three degrees of freedom. We here report the observation of chaotic soliton-pair molecules within an ultrafast fiber laser, by means of a direct measurement of the relative optical pulse separation with sub-femtosecond precision in real time. Moreover, we demonstrate an all-optical control of the chaotic dynamics followed by the soliton molecule, by injecting a modulated optical signal that resynchronizes the internal periodic vibration of soliton molecule.
