Planar metasurfaces are a valuable tool to achieve custom-tailored photoluminescence from quantum emitters. The incorporation of a WSe2 monolayer into a photonic crystal slab with geometric phase defects enables spin-dependent manipulation of the emission from valley excitons of the WSe2, as well as from randomly placed quantum emitters.
