A promising route for the development of opto-elelctronic technology is to use terahertz radiation modulate optical properties semiconductors. Here we demonstrate dynamical control photoluminescence (PL) emission in few-layer InSe using picosecond pulses. We observe a strong PL quenching (up 50%) after arrival pulse followed by reversible recovery on time scale 50ps at T =10K. Microscopic calcu...
