Broadband Few-Layer MoS2Saturable Absorbers

The bandgaps of monolayer and bulk molybdenum sulfide (MoS2) result in that they are far from suitable for application as a saturable absorption device. In this paper, the operation of a broadband MoS2 saturable absorber is demonstrated by the introduction of suitable defects. It is believed that the results provide some inspiration in the investigation of two-dimensional optoelectronic materials.
