Flat optics nanoarrays based on few-layer MoS2 are homogeneously fabricated over large-area (cm2) transparent templates, demonstrating effective tailoring of the photon absorption in two-dimensional (2D) transition-metal dichalcogenide (TMD) layers. The subwavelength subtractive re-shaping of the few-layer MoS2 film into a one-dimensional (1D)...

A cost effective method to tailor the optical response of large-area nanosheets of 2D materials is described. A reduced effective metalayer model is introduced to capture the key-role of the out-of-plane component of the dielectric tensor. Such a model indicates that the optical extinction of 2D materials can be strongly altered by controlling...
