Abstract: A process for plasmonic-based high resolution color printing is provided. The process includes a) providing a nanostructured substrate surface having a reverse structure geometry comprised of nanopits and nanoposts on a support, and b) forming a conformal continuous metal coating over the nanostructured substrate surface to generate a continuous metal film, the continuous metal film defining nanostructures for the plasmonic-based high resolution color printing, wherein a periodicity of the nanostructures is equal to or less than a diffraction limit of visible light. A nanostructured metal film or metal-film coated support obtained by the process and a method for generating a color image are also provided.

Abstract: This document describes a spatial light modulator that comprises a pixel array having a plurality of pixels whereby each pixel in this array is communicatively coupled to a digital pixel circuit which are in turn all coupled to a bit-plane control circuit. The bit-plane control circuit is configured to generate, using a Pulse Code Modulation (PCM) algorithm, bit-plane signals that are used to control the sample and hold functions performed by each of the digital pixel circuits so that the pixel array may carry out its scanning function accurately and in a power efficient manner.
