“…In particular, the ability to produce on-demand bound solitons is crucial for optical data-processing schemes 25 , optical switching 26 , storage 27 , and soliton trapping 28 . For example, the generation of four distinct types of bound solitons, each with different phase differences, can be regulated by manipulating the energy exchange between the solitons 29 . Researchers have divided the dispersion into a real part and an imaginary part to control the separation by encoding the phase and amplitude in the hologram of the liquid crystal spatial light modulator 30 , thereby realizing quaternary coding by the above-mentioned bound solitons 29 , 30 .…”

Temporal solitons have been the focus of much research due to their fascinating physical properties. These solitons can form bound states, which are fundamentally crucial modes in fiber laser and present striking analogies with their matter molecules counterparts, which means they have potential applications in large-capacity transmission and all-optical information storage. Although traditionally, second-order dispersion has been the dominant dispersion for conventional solitons, recent experimental and theoretical research has shown that pure-high-even-order dispersion (PHEOD) solitons with energy-width scaling can arise from the interaction of arbitrary negative-even-order dispersion and Kerr nonlinearity. Despite these advancements, research on the bound states of PHEOD solitons is currently non-existent. In this study, we obtained PHEOD bound solitons in a fiber laser using an intra-cavity spectral pulse shaper for high-order dispersion management. Specifically, we experimentally demonstrate the existence of PHEOD solitons and PHEOD bound solitons with pure-quartic, -sextic, -octic, and -decic dispersion. Numerical simulations corroborate these experimental observations. Furthermore, vibrating phase PHEOD bound soliton pairs, sliding phase PHEOD bound soliton pairs, and hybrid phase PHEOD bound tri-soliton are discovered and characterized. These results broaden the fundamental understanding of solitons and show the universality of multi-soliton patterns.

“…However, the separations of bound states are dictated by laser-specific effects such as Raman scattering or intracavity reflexes and cannot or only slowly be adjusted ( 12 , 15 , 16 ). While intracavity modulators and pulse shapers offer additional degrees of control ( 17 , 18 ), their slow temporal response affects entire groups of solitons simultaneously. Thus, soliton control is currently limited in efficiency, speed, and repeatability, and flexible means for soliton control are essentially absent.…”

Ultrafast science builds on dynamic compositions of precisely timed light pulses, and evolving groups of pulses are observed in almost every mode-locked laser. However, the underlying physics has rarely been controlled or used until now. Here, we demonstrate a general approach to control soliton motion inside a dual-comb laser and the programmable synthesis of ultrashort pulse patterns. Introducing single-pulse modulation inside an Er:fiber laser, we rapidly shift the timing between two temporally separated soliton combs. Their superposition outside the cavity yields ultrashort soliton sequences. On the basis of real-time spectral interferometry, we observe the deterministic switching of intersoliton separation arising from the interplay of attracting and repulsing forces via ultrafast nonlinearity and laser gain dynamics. Harnessing these insights, we demonstrate the high-speed all-optical synthesis of nano- to picosecond pump-probe delays and programmable free-form soliton trajectories. This concept may pave the way to a new class of all-optical delay generators for ultrafast measurements at unprecedented high tuning, cycling, and acquisition speeds.

This study employs real-time Fourier transform spectroscopy to investigate the pulsation dynamics of soliton molecules in a mode-locked erbium-doped fiber laser, utilizing pump intensity modulation. By manipulating the driving voltage of the pump source, we systematically observe and characterize the impact of external modulation signals on the amplitude, period, pulsation frequency, and the relative phase evolution among the pulsating soliton molecules within their spectra.The results demonstrate that, under specific conditions of pump intensity modulation, the pulsation period of soliton molecule spectra can be precisely regulated by the pump modulation frequency. Concurrently, the amplitude of soliton molecule pulsations and the evolution of relative phase among the solitons are intricately tied to the pump modulation frequency. At lower modulation frequencies, such as 1 kHz, the relative phase among the pulses within the soliton molecule exhibits a sliding-type dynamics as a function of propagation time.As the modulation frequency gradually increases, e.g., to 5 kHz, a scenario emerges where three soliton molecules are generated. Notably, both the soliton spacing and relative phase undergo synchronous adjustments influenced by the pump modulation. With further escalation of the modulation frequency, such as to 20 kHz, the relative phase evolution among the pulses within the soliton molecule gradually descends into chaos. This observation suggests the plausible existence of an inherent resonant frequency associated with pulsating soliton molecules, which has direct implications for their stability.The findings of this research hold significant relevance for advancing our comprehension of soliton molecule generation and enhancing their stability. Furthermore, they offer valuable insights into the broader domain of all-optical manipulation and applications of soliton molecules, as well as their utilization in pulse encoding within mode-locked laser systems.
