Abstract

We present the droplet method for liquid phase exfoliated reduced graphene oxide (r-GO) and black phosphorus (BP) saturable absorbers fabrication. By using this fast and powerful technique, nanomaterials/polymer-based films were directly transferred to optical fiber end-face and used as all-fiber saturable absorbers in an Erbium-doped fiber laser. As results, spectrum bandwidth of 7.30 nm and pulses as short as 570 fs could be generated, proving the reliability, practicability and robustness of this method for mode-locking applications.
