Abstract
Black arsenic phosphorus (b-AsP) is a novel two-dimensional (2D) material. It has aroused extensive interest in many fields thanks to its excellent performance of broad tunability band gap and high carrier mobility. In this paper, 2D b-AsP ultra-thin nanosheets were successfully prepared and systemically characterized. Under the influence of evanescent field effect, 2D b-AsP nanosheets is successfully prepared as a fiber-based saturable absorber (SA). Mode-locked pulses based on 2D b-AsP SA are generated in an Er-doped fiber laser, corresponding to the maximum repetition rate of 11.5 MHz and pulse duration of 807 fs. These results show that 2D b-AsP has excellent application potential in ultrafast photonics and photodetectors, etc.
