Abstract: 

2D materials (2DMs), due to spin-valley locking degree of freedom,  exhibit strongly bound exciton and chiral optical selection rules and  become promising material candidates for optoelectronic and  spin/valleytronic devices. Over the last decade, the manifesting of 2D  materials by circularly polarized lights expedites tremendous  fascinating phenomena, such as valley/exciton Hall effect, Moiré  exciton, optical Stark effect, circular dichroism, circularly polarized  photoluminescence, and spintronic property. In this review, recent  advance in the interaction of circularly polarized light with 2D  materials covering from graphene, black phosphorous, transition metal  dichalcogenides, van der Waals heterostructures as well as small  proportion of quasi-2D perovskites and topological materials, is  overviewed. The confronted challenges and theoretical and experimental  opportunities are also discussed, attempting to accelerate the  prosperity of chiral light-2DMs interactions.
