Abstract

Colors observed in nature are very important to form our perception of an object as well as its design. The desire to reproduce vivid colors such as those found in birds, fishes, flowers and insects has driven extensive research into nanostructured surfaces. Structural colors based on surface plasmon resonance (SPR) have played an important role in this field due to its high spatial resolution. Creating vivid color reflecting surfaces is still a major challenge and could revolutionize low power consumption image displays. Here we combine diffraction and plasmonic effects to design bright and vivid-color reflecting surfaces. The periodic reflection patterns are designed through genetic algorithm optimization and are defined in aluminum coated silicon chips.
