TL;DR: The results demonstrate that the microfiber-based TI photonic device can operate as both the high nonlinear optical component and the SA in fiber lasers, and could also find other applications in the related fields of photonics.

TL;DR: The generation of a femtosecond pulse in a fiber ring laser by using a polyvinyl alcohol (PVA)-based molybdenum disulfide (MoS(2) SA) saturable absorber indicates that the filmy PVA-based MoS( 2) SA is indeed a good candidate for an ultrafast saturable absorption device.

TL;DR: The results not only demonstrate that black phosphorus might be another promising SA material for ultrafast photonics, but also provide a practical solution to solve the optical damage problem of black phosphorus by assembling with waveguide structures such as microfiber.

TL;DR: In this paper, a microfiber-based few-layer black phosphorus (BP) SA device is proposed to solve the optical damage problem of black phosphorus by assembling with waveguide structures such as micro-fiber, which can deliver the mode-locked pulse with duration down to 940 fs with central wavelength tunable from 1532 nm to 1570 nm.

TL;DR: The experimental results demonstrate that the PVA could be an excellent host material for fabricating high-performance TISA, and indicate that the filmy PVA-TISA is indeed a good candidate for ultrafast saturable absorption device.
