The dissipative solitons (DS) generated in fiber oscillators with mode-locking mechanism
based on nonlinear polarization evolution in a single-mode fiber exhibit stability and energy …

Stripe solitons (SSs), the special localized wavepackets exhibiting periodic modulations, are
identified in condensed matter physics and nonlinear science. Here, giant‐chirp and chirp …

Chirp-free solitons have been mainly achieved with anomalous-dispersion fiber lasers by
the balance of dispersive and nonlinear effects, and the single-pulse energy is constrained …
