Soliton molecules (SMs) are fundamentally important modes in nonlinear optical systems. It
is a challenge to experimentally produce SMs with the required temporal separation (TS) in …

Bismuthene, a mono-elemental two-dimensional material with a novel kind of few-layer
structure purely consisting of bismuth, has been predicted to have a prominent optical …

A hybrid no-core fiber (NCF)–graded index multimode fiber (GIMF) structure is used as a
saturable absorber (SA) for mode-locked laser operation. Such an SA supports various …

Methods of output wavelength tuning in short-pulsed fibre lasers are analysed. Many of them
rely on spectral selection principles long used in other types of lasers. For compatibility with …

A tunable mode-locked ytterbium-doped fiber laser with a tuning range of 55 nm is
demonstrated in this paper. Currently, this is the widest tuning range for all-normal …

Ultrafast fiber lasers have been serving as an ideal playground for spreading the extensive
industrial applications and exploring the optics nonlinear dynamics. Here, we report a …

We report on the experimental observation of wavelength-switchable bound solitons in a
passively mode-locked erbium-doped fiber ring laser based on a tapered graded-index …

We report on the generation of high-order solitons with order continuously adjustable in an
erbium-doped fiber laser mode-locked by a graded index multimode fiber–step index …

We have demonstrated the generation of multicolor noise-like pulse complex in a passively
Yb-doped mode-locked fiber laser based on a single mode-graded index multimode-single …

Nonreciprocity of traditional filters severely limits their tunability. To tap alternatives, here we
propose hybrid wavelength manipulation with enhanced ambient-thermal-drift adaptability in …
