Nonlinear optical fibres have been employed for a vast number of applications, including
optical frequency conversion, ultrafast laser and optical communication,,–. In current …

Silica-based optical fibres are a workhorse of nonlinear optics, providing ready access to a
range of nonlinear phenomena including solitons and self-phase modulation. However, they …

The centrosymmetric nature of silica fibre precludes the realisation of second-order
nonlinear processes in optical fibre systems. Recently, the integration of 2D materials with …

Ultrafast lasers play an important role in a variety of applications ranging from optical
communications to medical diagnostics and industrial materials processing. Graphene and …

Passive Q-switching or mode-locking by placing a saturable absorber inside the laser cavity
is one of the most effective and popular techniques for pulse generation. However, most of …

Transition-metal dichalcogenides (TMDCs) and black phosphorus (BP) are typical 2D
materials with layer-dependent bandgaps, which are emerging as promising saturable …

Optical microfibres have recently attracted much attention for nonlinear applications, due to
their tight modal confinement. Here, we report broadband third harmonic generation based …

We fabricate titanium disulfide (TiS_2) using a liquid exfoliation method and subsequently a
TiS_2-based device by optically depositing the TiS_2 material onto the microfiber. This …

In this Letter, high-quality WS_2 film and MoS_2 film were vertically stacked on the tip of a
single-mode fiber in turns to form heterostructure (WS_2-MoS_2-WS_2)-based saturable …

The explosive success of graphene opens a new era of ultrathin 2D materials. It has been
realized that the van der Waals layered materials with atomic and less atomic thickness can …
