Monolayer transition metal dichalcogenides have intrinsic spin-valley degrees of freedom, making it appealing to exploit valleytronic and optoelectronic applications at the nanoscale. Here, we demonstrate that a chiral plasmonic antenna consisting of two stacked gold nanorods can modulate strongly valley-polarized photoluminescence (PL) of monolayer MoS<sub>2</sub> in a broad spectral range at room temperature. The valley-polarized PL of the MoS<sub>2</sub> using the antenna can reach up to ~47% ...[more]
