Paper Abstract

Two-dimensional (2D) semiconductors possess unique optoelectronic properties and has become a research hot-spot in recent years. Realized that the sizable and thickness-dependent bandgap offers transition metal dichalcogenides (TMDCs) a huge potential in the development of photonic devices with high performance and unique functions, we studied extensively the ultrafast NLO property of a range of TMDCs. TMDCs with high-quality layered nanosheets were prepared using liquid-phase-exfoliation technique. Ultrafast saturable absorption, two-photon-absorption were observed from the 2D nanostructures. The exciting results open up the door to 2D photonic nano-devices, such as optical switches, mode-lockers, optical limiters, etc., capable of ultrafast response and broadband tunability.
