==IMAGE SENSORS INCLUDING META-STRUCTURE FOR COLOR SEPARATION AND ELECTRONIC DEVICES INCLUDING IMAGE SENSOR - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18142219 titled 'IMAGE SENSORS INCLUDING META-STRUCTURE FOR COLOR SEPARATION AND ELECTRONIC DEVICES INCLUDING IMAGE SENSOR

==Simplified Explanation==

- The patent application describes meta-optical elements and image sensors that utilize a meta-pattern.
- The image sensor consists of multiple pixels, each containing a photoelectric conversion layer with at least one photoelectric conversion element.
- A color routing meta-structure layer is positioned opposite the photoelectric conversion layer in each pixel.
- The color routing meta-structure layer has a symmetrical structure with respect to the center of the pixel.
- The meta-structure within the color routing meta-structure layer has a multi-layer structure with a varying refractive index perpendicular to the surface where light is incident.
- The purpose of this innovation is to improve the performance and efficiency of image sensors by optimizing the routing of different colors of light within each pixel.


==Original Abstract Submitted==

The present disclosure provides meta-optical elements and image sensors using a meta-pattern and apparatuses including the image sensors. In an embodiment, an image sensor includes a plurality of pixels. Each pixel of the plurality of pixels includes a photoelectric conversion layer including at least one photoelectric conversion element, and a color routing meta-structure layer provided at a position facing the photoelectric conversion layer. The color routing meta-structure layer includes a meta-structure having a symmetrical structure with respect to a center of a corresponding pixel, and a multi-layer structure having a refractive index that varies in a direction perpendicular to a light-incident surface.
