Direct-write laser-assisted altering of metasurfaces

Abstract

This disclosure provides a method for altering a nanostructured surface of an optic, including placing the optic under vacuum and exposing an area of the nanostructured surface to an irradiation source for a predetermined time and impinging energy such that the irradiation changes a nanostructure of the surface in the exposed area thereby altering an optical property. Further, this disclosure provides a system for altering a nanostructured surface of an optic, including a vacuum chamber for placing the optic under vacuum, an irradiation source configured to expose at least a portion of an area of the nanostructured surface with irradiation, and a processor in electronic communication with the irradiation source and configured to energize the irradiation source for a predetermined time and irradiation energy so as to change a nanostructure of the surface in the exposed area thereby altering an optical property.
