Saturable plasmonic metasurfaces for laser mode locking

(Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, Chinese Academy) Nonlinear plasmonics, an interdisciplinary subject combining nonlinear and sub-wavelength optics, is an emerging field in nanoscience and nanotechnology. However, practical applications remain limited to date. Here, scientists from France, China and Brazil have implemented plasmonic saturable metasurfaces into a fiber laser architecture to achieve soliton mode locking. This work opens new perspe...
