A method for manufacturing an optical metasurface is configured to operate in a given working spectral band. The method comprises: obtaining a 2D array of patterns, each comprising one or more nanostructures forming dielectric elements that are resonant in said working spectral band, said nanostructures being formed in at least one photosensitive dielectric medium; exposing said 2D array to a writing electromagnetic wave having at least one wavelength in said photosensitivity spectral band, said writing wave having a spatial energy distribution in a plane of the 2D array that is a function of an intended phase profile, so that each pattern of the 2D array produces on an incident electromagnetic wave having a wavelength in the working spectral band, a phase variation corresponding to a refractive index variation experienced by said pattern during said exposure.

Systems and methods are provided that may utilize a glass substrate to selectively withdraw exfoliated graphene from a high-energy interface between immiscible solvents. The exfoliated graphene preferentially adheres to the surface of the glass substrate for withdrawal from the noted high energy interface, leaving behind the graphite (which is too large to be effectively adsorbed relative to the glass substrate). The disclosed systems and methods are easily implemented and offer significant advantages for graphene production relative to conventional systems and methods, e.g., the disclosed systems/methods do not require the input of heat or mechanical energy which translates to processes that are both cheaper to run and do not result in damage to the graphene. Still further, the disclosed systems/methods do not require chemical modification of the graphene, again lowering the cost considerably and not damaging the graphene structure.
