Paper Abstract

This paper describes digital printing of optical metasurfaces, by holographic laser post-writing on nano-textured, metal-coated template surfaces. Holographic laser printing with a spatial light modulator (SLM) provides multiple pixel exposure and high power endurance, where individual template nano-stuctures are thermo-optically modified by resonant absorption. Ultra-high printing resolution, beyond 100,000 Dots per inch (DPI) is achieved - enabling nano-scale digital laser printing for mass customization of optical components and individualized decoration of consumer products. We present laser printed structural colors and flat optics components, such as Fresnel Zone Plates (FZP) and Axicons.
