All-optical nonreciprocity due to valley polarization pumping in transition metal dichalcogenides

Nonreciprocity is viewed as a useful feature for many future optical devices. Here, the authors observe all-optically-induced nonreciprocal dichroism in monolayer WS2, which is explained by valley-selective response.
