Document Type and Number:
WIPO Patent Application WO/2020/212925
Kind Code:
A8
Abstract:
A computer-implemented method of designing an optical device that comprises an aperiodic matrix of nanostructures (NR) made of a predetermined material, adapted to modulate a near field incident optical radiation and examples of optical devices obtainable by means of the method are described. A precursor array of nanostructures (NR) that comprises a regular periodic arrangement of replicas of a unit cell is defined (100) in a predetermined two-dimensional reference system associated with a substrate. Starting from the precursor array, a configuration pattern of the aperiodic matrix of nanostructures (NR) is calculated by modifying (200, 300) at least one spatial parameter of the nanostructure unit cell in the regular periodic arrangement of replicas of the unit cell according to a predetermined mathematical model. A method for manufacturing an optical device comprises controlling a predetermined technique of structuring the substrate in accordance with the calculated configuration model.
