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 …

A mode-locked all-fiber laser based on the nonlinear multimode interference (NL-MMI) effect
of the graded-index multimode fiber (GIMF) is proposed and demonstrated. The saturable …

A novel mode-locking method based on the nonlinear multimode interference in the
stretched graded-index multimode optical fiber (GIMF) is proposed in this Letter. The simple …

Multimode optical fibers have recently reemerged as a viable platform for addressing a
number of long-standing issues associated with information bandwidth requirements and …

We demonstrate, for the first time, use of a stretched single mode-graded-index multimode-
single mode fiber (SMF-GIMF-SMF) structure as a saturable absorber (SA) for a passively …

We have implemented wavelength-tunable and dual-wavelength in an ytterbium-doped
passively mode-locked fiber laser using a single mode-graded index multimode-single …

We developed a passively mode-locked ytterbium-doped fiber laser based on offset-spliced
graded index multimode fibers (OS-GIMFs), where OS-GIMFs play the role of saturable …

Advancements in computational capabilities along with the possibility of accessing high
power levels have stimulated a reconsideration of multimode fibers. Multimode fibers are …

We provide an all fiber spectrally flat supercontinuum (SC) source generated by pumping a
20 m graded-index multimode fiber (MMF). The fiber pigtails of the all-fiber pump pulse laser …

We demonstrate how spatial beam self-cleaning and supercontinuum generation in graded-
index multimode optical fibers can be directly applied in multiplex coherent anti-Stokes …
