“…In particular, optical RWs go beyond the significant wave height by a factor of 2, which have been widely investigated in different nonlinear optical systems, such as mode-locked Ti:sapphire lasers [94], Raman fibre amplifiers [95,96], parametric processes [97] and fibre lasers [98][99][100][101][102][103][104][105][106]. Figure 26 shows typical characterizations of dissipative RWs, which were obtained in a Tm-doped fibre laser mode-locked by monolayer MoS 2 [107].…”

“…When recording approximately 500 thousand of trace samples on the oscilloscope, a significant deviation can be observed from Gaussian statistics in high-amplitude part with long tail in the histogram of Figure 26e. The significant wave height (SWH) is defined as the mean amplitude of the highest third of the waves [99,101]. The highest recorded amplitude is 1596.5 mV, around 2.36 times that of the SWH of 677.4 mV, revealing the generation of DRWs.…”

Featured Application: High-capacity telecommunication, advanced time-resolved spectroscopy, self-organization and chaos in dissipative systems. Abstract:Benefiting from ultrafast temporal resolution, broadband spectral bandwidth, as well as high peak power, passively mode-locked fibre lasers have attracted growing interest and exhibited great potential from fundamental sciences to industrial and military applications. As a nonlinear system containing complex interactions from gain, loss, nonlinearity, dispersion, etc., ultrafast fibre lasers deliver not only conventional single soliton but also soliton bunching with different types. In analogy to molecules consisting of several atoms in chemistry, soliton molecules (in other words, bound solitons) in fibre lasers are of vital importance for in-depth understanding of the nonlinear interaction mechanism and further exploration for high-capacity fibre-optic communications. In this Review, we summarize the state-of-the-art advances on soliton molecules in ultrafast fibre lasers. A variety of soliton molecules with different numbers of soliton, phase-differences and pulse separations were experimentally observed owing to the flexibility of parameters such as mode-locking techniques and dispersion control. Numerical simulations clearly unravel how different nonlinear interactions contribute to formation of soliton molecules. Analysis of the stability and the underlying physical mechanisms of bound solitons bring important insights to this field. For a complete view of nonlinear optical phenomena in fibre lasers, other dissipative states such as vibrating soliton pairs, soliton rains, rogue waves and coexisting dissipative solitons are also discussed. With development of advanced real-time detection techniques, the internal motion of different pulsing states is anticipated to be characterized, rendering fibre lasers a versatile platform for nonlinear complex dynamics and various practical applications.

“…Apparently, a real-time high-resolution spectro-temporal analyzer operating in a continuous mode is yet to be demonstrated for better understanding the nonlinear optical physics as well as optimizing the laser performances. Photonic time-stretch through dispersive chirp has recently been demonstrated as a highthroughput single-shot spectral analyzer [31][32][33] and has greatly enriched researches on nonlinear physics, e.g., supercontinuum generation [34], optical rogue wave observation [24,35,36], soliton explosion [37,38], as well as mode-locking and soliton-molecule formation [39,40]. Despite its superior performance in fs-ps regime, typically for transformlimited short pulses, time-stretch spectroscope (TSS) is inadequate for CW/quasi-CW optical signal, see Appendix 1.…”

Abstract:Spectro-temporal studies on the nonlinear physics of complex laser dynamics are essential in approaching its ultimate performance as well as understanding interdisciplinary problems. Unfortunately, it has long been limited by the insufficient spectro-temporal resolving power of conventional temporal and spectral analyzers, particularly when an indefinite optical signal ensemble contains polychromatic mixtures of continuous-wave (CW) and short pulse. In this work, we propose a real-time optical spectro-temporal analyzer (ROSTA) with three synchronized processing channels (i.e., multi-core) for single-shot studies on laser dynamics. It simultaneously provides temporal resolutions of ~70 ps in the time domain and 10's ns (or 10's MHz frame rate) in the spectral domain, as well as a high spectral resolution for multiscale optical inputs, i.e., ranging from CW to fs pulses. Its nontrivial record length of up to 6.4 ms enables continuous observations of non-repetitive optical events over an extensive time period -equivalent to a propagation distance of ~1900 km. To showcase its practical applications, ROSTA is applied to visualize the onset of passive modelocking of a fiber laser, and interesting phenomena, i.e., evolution from quasi-CW noise burst to strong shock, transition from fluctuation to mode-locking, and coexistence of CW and mode-locked pulses, have been spectro-temporally observed in a single-shot manner for the first time. It is anticipated that ROSTA will be a powerful technology for spectro-temporal optical diagnosis in different areas involving polychromatic transients. 1335-1337 (2008). 11. C. Xu and F. W.

“…In photonics, the dispersive Fourier-transform (DFT) measurement technique has recently permitted to experimentally resolve complex ultrafast nonlinear phenomena, from stochastic fluctuations in modulation instability to optical rogue waves and soliton explosions in ultrafast fiber lasers [25][26][27]. The principle of the DFT technique consists of stretching a train of optical pulses in a dispersive medium that cumulates a group-velocity dispersion large enough to map the spectrum of each optical pulse into a temporal waveform, which is a conceptual analogue to the far-field limit in paraxial diffraction [28].…”

Real-time access to the internal ultrafast dynamics of complex dissipative optical systems opens new explorations of pulse-pulse interactions and dynamic patterns. We present the first direct experimental evidence of the internal motion of a dissipative optical soliton molecule generated in a passively modelocked erbium-doped fiber laser. We map the internal motions of a soliton pair molecule by using a dispersive Fourier-transform imaging technique, revealing different categories of internal pulsations, including vibration-like and phase drifting dynamics. Our experiments agree well with numerical predictions and bring insights to the analogy between self-organized states of lights and states of the matter.
