Abstract

Recently, with the development of fabrication technology, sub-nm patterning has been developed, and it has become sufficiently possible to make a nanostructure having a sub-wavelength period. For this reason, metasurface has been a topic of increasing interest in the field of nanophotonics. In this paper, we report the results of realizing mode locking by inserting a metasurface in the form of a saturable absorber into an Yb-doped fiber laser. The metasurface-based saturable absorber has the advantage of reducing the loss due to the deterioration of the existing saturable absorber.
