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 …

We review the research status of the mechanism and technology of all-fiber mode-locked
ultrafast laser with multimode fiber based saturable absorber. Using novel all-fiber structured …

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 …

We demonstrated an ultrafast Yb-doped fiber laser with a single mode fiber-graded index
multimode fiber-single mode fiber (SMF-GIMF-SMF) structure based saturable absorber. The …

Bound solitons have become a hot topic in the field of nonlinear optics due to their potential
applications in optical communication, information processing and radar systems. However …

We experimentally investigated GeTe as a modulator for generating conventional soliton,
soliton molecule and bright-dark soliton pair in an Er-doped fiber laser (EDFL) for the first …

In the present work, the uniformly sized bismuthene quantum dots (BiQDs) with an average
diameter of 26 nm were fabricated via the solvothermal approach. By transferring the BiQDs …

In this work, the Ti 3 C 2 MXene was modified with Fe 3 O 4 nanoparticles to obtain a
composite with in-plane optical anisotropy and surface plasmon properties. Based on a side …

A mode-locked high pulse energy fiber laser with a linear cavity by using an all-fiber
structured graded index multimode fiber (GIMF) based saturable absorber (SA) is presented …

The recently discovered phosphorus allotrope, violet phosphorus, has predictable ultrafast
nonlinear optical (NLO) properties and potential for photonics applications. Here, we …
