Summary: This study presents theoretical investigations on the filter-induced instability mechanism in passive driven fiber resonators. Numerical simulations demonstrate coherent frequency combs with rates up to sub-terahertz level. The comparison with other types of instabilities reveals the intrinsic distinction in the family of modulation instabilities. These findings have significant implications for the development of ultrahigh-repetition-rate frequency comb generation.

Summary: In this study, the characteristics of dissipative pure-quartic soliton (DPQS) generation in a fiber laser were investigated. The experimental results demonstrate that DPQS features shape-preserving propagation with an asymmetrical temporal profile. The asymmetrical temporal profile of DPQS is caused by the mismatching of phase shift profiles resulting from self-phase modulation and fourth-order dispersion. Compared to conventional dissipative solitons, DPQS exhibits a higher energy-scaling ability.

Summary: This numerical investigation explores the pulsating dynamics of pure-quartic solitons (PQSs) in a passively mode-locked fiber laser. The results reveal that the PQS can alternate between stable single soliton and pulsating regimes multiple times, attributed to an imperfect counterbalance between self-phase modulation and fourth-order dispersion-induced phase shifts. Additionally, soliton creeping behavior and wavelength shifts are observed during the pulsating process.

Summary: Investigation of the characteristics and dynamics of pure quartic solitons (PQSs) in the presence of the Raman effect reveals an intermediate stable state in the parameter space, which has not been discovered in other soliton regimes. Stabilty analysis is performed to study the spatial dynamics in the context of the Raman PQS.

Summary: This theoretical study investigated the vector properties of quartic solitons in a pure fourth-order-dispersion birefringent fiber and a quartic-dispersion-dominant mode-locked fiber laser. It was found that a vector quartic soliton in the birefringent fiber still preserves a Gaussian shape with some distinctions, and pulse shaping in the mode-locked laser cavity can facilitate the formation of Kelly sidebands and distortion of oscillatory tails. Dynamic evolutions of quartic group-velocity-locked and polarization-rotating vector solitons were shown to enrich the nonlinear community of VQSs.

Summary: Pure quartic solitons (PQS) have been demonstrated as a new class of solitons in recent years, offering innovations in nonlinear optics and potential applications. Numerical investigation in a dispersion-engineered aluminum nitride (AlN) micro-cavity shows that PQS can be generated with the support of a well-designed shallow-trench waveguide structure. Spectral recoil and soliton self-frequency shift are observed in the PQS spectrum.

Summary: Solitons are self-sustaining particle-like wave packets found throughout nature. A new class of optical solitons with pulses characterized by large and positive chirp in normal dispersion resonators with strong spectral filtering is introduced. Numerical simulations and experimental observations show stable waveforms, including dissipative solitons characterized by large frequency chirp, with potential applications in spectroscopy, communications, and metrology.

Summary: Solitons are wave packets that can propagate without changing shape by balancing nonlinear effects with the effects of dispersion. High-order dispersion has been shown to enrich the phenomenon of solitons and may lead to novel applications in photonics. This tutorial reviews exciting developments in this field, including pure-quartic solitons and their generalizations, covering theory, numerics, and experimental results.

Summary: Recent observations have shown the existence of a series of optical pulse solitons that balance self-phase modulation and arbitrary negative pure, even-order dispersion, including sextic, octic, decic, and even 16th-order dispersion solitons. These results broaden the fundamental understanding of solitons and open up avenues for engineering ultrafast pulses in nonlinear optics and its applications.
