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 …

Driven by new two-dimensional materials, great changes and progress have taken place in
the field of ultrafast photonics in recent years. Among them, the emerging single element two …

Abstract Since the mid-(2–20 μm) and far-infrared (20–1000 μm) regions cover the vibration
and rotation characteristic “fingerprint” spectra of many gas molecules and three …

The tunable bandgap from 0.3 eV to 2 eV of black phosphorus (BP) makes it to fill the gap in
graphene. When studying the properties of BP more comprehensive, scientists have …

This study introduces gold nanoparticles (Au-NPs) coated on side-polished fiber (SPF) as a
saturable absorber (SA) material in the development of a mode-locked erbium-doped fiber …

We reported a newly fabricated saturable absorber (SA) namely Lutetium oxide (Lu 2 O 3)
thin film for generating a stable and compact mode-locked Erbium-doped fibre laser (EDFL) …

Q switching was demonstrated in an Erbium-doped fiber laser by utilizing Indium Selenide
(In 2 Se 3)-PVA as a passive saturable absorber (SA). The In 2 Se 3 PVA thin film was …

Passively pulse dual-wavelength ytterbium-doped fiber laser (YDFL) around 1 μm utilizing
titania–carbon nanocomposite (TiO 2–C NC) thin film as the optical modulator is …

Abstract Two-dimensional (2D) materials have attracted extensive interests due to their wide
range of electronic and optical properties. After continuous and extensive research, black …

Abstract Two-dimensional (2D) layered materials exhibit strong light-matter interactions,
