Abstract
Here the authors report binary phase supercritical lenses by patterning monolayer TMD materials. Through placement of atomic thin 2D TMD with sufficient absorption, a spot of critical coupling is created to facilitate a π phase jump and subdiffraction focusing over bandwidth of 150 nm in visible range.
