Solitons are stable localized wave packets that can propagate long distance in dispersive
media without changing their shapes. As particle-like nonlinear localized waves, solitons …

Linear multimode optical systems have enabled clean experimental observations and the
applications of numerous phenomena that continually extend the boundaries of wave …

Cylindrical vector beams and vortex beams, two types of typical singular optical beams
characterized by axially symmetric polarization and helical phase front, possess the unique …

Ultrashort optical pulses propagating in a dissipative nonlinear system can interact and bind
stably, forming optical soliton molecules. Soliton molecules in ultrafast lasers are under …

Multimode fiber (MMF) lasers are emerging as a remarkable testbed to study nonlinear
spatiotemporal physics with potential applications spanning from high energy pulse …

Mode-locking is a process in which different modes of an optical resonator establish stable
synchronization through non-linear interactions. This self-organization underlies light …

We provide a perspective overview of the emerging field of nonlinear optics in multimode
optical fibers. These fibers enable new methods for the ultrafast light-activated control of …

Rogue waves (RWs) are rare, extreme amplitude, localized wave packets, which have
received much interest recently in different areas of physics. Fiber lasers with their abundant …

The performance of fiber mode-locked lasers is limited due to the high nonlinearity induced
by the spatial confinement of the single-mode fiber core. To massively increase the pulse …

Multimode fibers (MMFs) have attracted interest because of their larger mode area and
additional spatial degrees of freedom compared with single-mode fibers. Recently, MMFs …
