“…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.…”

Plasmonic color filtering has provided a range of new techniques for "printing" images at resolutions beyond the diffraction-limit, significantly improving upon what can be achieved using traditional, dye-based filtering methods. Here, a new approach to high-density data encoding is demonstrated using full color, dual-state plasmonic nanopixels, doubling the amount of information that can be stored in a unit-area. This technique is used to encode two data sets into a single set of pixels for the first time, generating vivid, near-full sRGB (standard Red Green Blue color space)color images and codes with polarization-switchable information states. Using a standard optical microscope, the smallest "unit" that can be read relates to 2 × 2 nanopixels (370 nm × 370 nm). As a result, dual-state nanopixels may prove significant for long-term, high-resolution optical image encoding, and counterfeit-prevention measures. over their microscale, dye-based counterparts. 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. Recent developments in the engineering and manipulation of materials on the nanoscale have given rise to a number of new techniques with the potential for physically encoding data and images into optically readable volumes and surfaces. [23,24] Using semiconductor quantum dots, [25][26][27] graphene, [28] and various super-resolution lithography techniques, [29][30][31][32][33][34] researchers are demonstrating novel 2D and 3D techniques that may enable the next generation of optical storage and encoding technologies. Plasmonic particles and filters have also seen applications in these research areas, with the aforementioned image encoding examples having been joined by demonstrations of their use in optical data storage. [23,24,[35][36][37] Here, we show a new utilization of image encoding using polarization multiplexed plasmonic filters, where, unlike previous studies that employed color or position switching in fixed images, [14,38] we show that two arbitrary, full-color images can be encoded into a single array of pixels. Our individual pixels are comprised of asymmetric cross-shaped nanoapertures in a thin film of aluminum. Each aperture is engineered to exhibit two independent plasmonic resonances which can be tuned across the sRGB (standard Red Green Blue) color-space (a single pixel can be encoded with any two arbitrary colors). We go on to show that by using the smallest visible unit ...

“…In that context, Yoon et al demonstrated a 1-D periodic amorphous Si thin-film grating structure that absorbs almost 90% of fully conical unpolarized light across the entire visible spectrum [1]. Cheng et al realized a 2-D periodic silver structure that exhibited nearly perfect absorption of incoherent light by plasmonic resonance in the visible spectral region [2]. Recently, techniques implementing absorption under coherent light interference have gained considerable attention due to several advantages including the use of linear optics and novel functionality not attainable by other means.…”

Experimental Evidence for Coherent Perfect Absorption in Guided-Mode Resonant Silicon Films

et al. 2016

We experimentally verify a new class of coherent absorbers based on guidedmode resonance effects in periodic thin films. We design a silicon-based resonant absorber that is fabricated and tested near the 1300-nm wavelength. Implementing phase control, the device can, in principle, be switched between full absorption and full scattering. The first experimental prototype presented herein shows ∼78% absorption in the inphase state. Nearly total scattering is realized in the out-of-phase state. The experimental results agree reasonably well with theory.

“…Although most of the devices presented here use a mixture of metal-dielectric multilayers so as to reduce the effects of the ohmic losses in metals [48][49][50], this costs extra time and money during fabrication [66][67][68][69]. So more recently all metal perfect absorbers [70] have been investigated.…”

In the past decade, the realisation of negative index materials has initiated extensive research into metamaterials. Perfect absorbers and reflectors are of particular interest as their usefulness is endless in a range of different fields and devices. Since it was originally shown that a device can achieve unity absorption of electromagnetic waves, it has become a hot area of research to develop perfect absorbers based on polarisation independence and incident angle independence, at a range of frequencies from microwave to optical ones. The amazing performance, flexibility, and tunability of these metamaterials will be discussed here, by presenting the different designs and working mechanisms that have been realised up to now. Their limitations and shortcomings will be addressed and future plans for perfect absorbers and reflectors will be suggested.
