Paper Abstract
We report on ultrafast-pulse generation in an erbium-doped fiber ring laser mode-locked by a graphene/WS2 van der Waals heterostructure saturable absorber. Atomic-layered WS2 is first synthesized on SiO2/Si substrate by the chemical vapor deposition (CVD) method, and then graphene/WS2 heterostructure is fabricated by transferring graphene onto the CVD-grown layered WS2. Taking advantage of excellent saturable absorption properties of the fabricated graphene/WS2 heterostructure, stable soliton pulses are successfully generated in the laser with a 3-dB spectral width of 2.3 nm and a pulse duration of 1.12 ps. Numerical simulations reproduce the mode-locked pulse emission in the experiment. Our research provides a new insight for tailoring versatile two-dimensional heterostructures so as to develop ultrafast photonic applications.
