The Plasmonic Pixel: Large Area, Wide Gamut Color Reproduction Using Aluminum Nanostructures

Abstract: We demonstrate a new plasmonic pixel (PP) design that produces a full-color optical response over macroscopic dimensions. The pixel design employs arrays of aluminum nanorods "floating" above their Babinet complementary screen, Concepts from conventional cyan magenta yellow key (CMYK) printing techniques and red green blue (RGB) digital displays are integrated with nanophotonic design principles and adapted to the production of PP elements. The fundamental PP color blocks of CMYK are implemented via a composit… Show more

“…Recently, structural color systems based on engineered nanophotonic materials have emerged as an appealing alternative to absorptive dyes. [1][2][3][4][5][6][7][8][9][10][11][12] Among these examples are color filters based on plasmonics; filters which rely on the resonant interaction between incident photo ns and the free-electrons of nanoscale metal structures. Thus far, filters based on positive nanostructures, [4,7,9,[11][12][13][14][15] filters based on cavity apertures, [2,[16][17][18] and filters which combine both strategies [8] have been shown, each with distinct fabrication and geometrical solutions to achieving color "nanopixels" for selective white-light separation.…”

“…Chief among these are their subwavelength dimensions (leading to ultradense, ultrathin pixel arrays), and their long-term environmental stability (they do not degrade or fade over time due to radiation exposure). As a result, plasmonic filters have been positioned as new technological solutions for subwavelength color printing, [1,4,[7][8][9]12] anticounterfeiting measures, [19,20] and RGB splitting for image sensors; [2,17,21,22] thus representing one of the most promising, technologically relevant areas of current plasmonic research activity. Here, we explore a new application of polarizationcontrolled plasmonic filters: dual output, full-color optical image encoding.…”

“…Surfaces with adjustable optical properties are extensively studied and of interest for sensing [1][2][3][4], controlled light absorption [5], color printing [6][7][8], among other applications. Plasmonics is one approach to enable special optical properties, like intense reflection, absorption or transmission in a targeted wavelength range.…”
