Abstract

The subwavelength structure based on metamaterials is widely used in the field of photonics due to its unique electromagnetic properties. Here, a Fabry-Perot-like cavity structure composed of aluminum and silicon materials is proposed, of which resonance peak can shift in the whole visible light band, and makes the materials display different colors. In addition, the edge detection algorithm is used to extract the edge position information of the image, so that the image represented by the structure color can be described more accurately. At the same time, the combination of structure color and algorithm upgrades the artificial representation of image information to intelligent processing. This work provides a valuable scheme for the design of simple nanostructures with multi physical mechanisms in the future.
