Nanofabrication of metafibers and the applications in ultrashort laser pulse generations.

Caption

a, Nanofabrication of plasmonic metafibers using standard electron-beam lithography (EBL) or focused ions beam milling (FIB) and the corresponding SEM images. b, Home-built ultrafast fibre laser integrating a plasmonic metafiber. c, Schematics of metafibers used as saturable absorbers. d, Nonlinear characterization of metafibers and the corresponding mode-locking performance. (d1) Power- and polarisation-dependent nonlinear transmission of a nanorod metasurface in resonant excitation conditions. The polar coordinates (P, 𝜃) represent the averaged power in the focus and the polarisation angle of the incident light. (d2) Autocorrelation trace of a single soliton at pump power of 58 mW.
