Printing technology based on plasmonic structures has many advantages overpigment based color printing such as high resolution, ultra-compact size andlow power consumption. However, due to high losses and broad resonance behaviorof metals in the visible spectrum, it becomes challenging to producewell-defined colors. Here, we investigate cross-shaped dielectricnanoresonators which enable high quality resonance in the visible spectralregime and, hence, high quality colors. We numerically predict andexperimentally demonstrate that the proposed all-dielectric nanostructuresexhibit high quality colors with selective wavelengths, in particular, due tolower losses as compared to metal based plasmonic filters. This results infundamental colors (RGB) with high hue and saturation. We further show that alarge gamut of colors can be achieved by selecting the appropriate length andwidth of individual $Si$ nanoantennas. Moreover, the proposed all-dielectricmetasurface based color filters can be integrated with the well maturedfabrication technology of electronic devices.
