Plasmonic Saturable Absorbers [PDF]

Advanced Photonics Research, 2021
Plasmonic materials are able to spatially confine light to a nanometer scale far smaller than the diffraction limit, resulting in drastically enhanced electrical field strength and stimulating applications in nonlinear optics, energy, and biomedicine. Resonant excitation of plasmonic nanostructures by ultrafast pulses results in a subpicosecond‐scale ...

Controlled Generation of Bright or Dark Solitons in a Fiber Laser by Intracavity Nonlinear Absorber

IEEE Photonics Journal, 2016
We numerically found that an intracavity nonlinear absorber (saturable absorber or reversed saturable absorber) plays a crucial role in the formation of dissipative bright or dark solitons in a fiber laser. The operation of an all-normal-dispersion fiber
