FIELD: nanophotonics.
SUBSTANCE: invention concerns an optical device. An optical device containing a source of optical radiation with a wavelength in its spectrum, made in the form of an image projector, and an optical element planar in the (x, y) plane, the normal of which makes an angle with the optical axis of the specified source of optical radiation. The optical element contains at least a first layer of optically transparent dielectric with a thickness and dielectric constant second layer of absorbent two-dimensional material thick and dielectric constant and an optically transparent substrate with dielectric constant . These layers and the substrate are made to form a point of topological darkness.
EFFECT: possibility of creating flat optics for ultra-thin structures with high quality images.
