  • Nano-posts have cylindrical shape with first and second refractive layers
  • Second refractive index is higher than first refractive index

Potential Applications

  • Improved image quality in digital cameras
  • Enhanced color accuracy in photography and video recording
  • Better performance in low light conditions

Problems Solved

  • Reduced color crosstalk in image sensors
  • Improved color reproduction in captured images
  • Enhanced sensitivity to different light wavelengths

Benefits

  • Higher quality images with accurate colors
  • Improved performance in various lighting conditions
  • Enhanced overall image sensor functionality


Original Abstract Submitted

An image sensor is provided. The image sensor includes: a photodetector with a plurality of photodetection cells; an interlayer device provided on the photodetector; and a color separation lens layer including a plurality of nano-posts disposed on the interlayer device and spaced apart from each other, the plurality of nano-posts focusing light of different spectra to at least two of the plurality of photodetection cells. Each of the plurality of nano-posts includes a first refractive layer having a first refractive index and a cylindrical shape, and a second refractive layer having a second refractive index and surrounding bottom and side surfaces of the first refractive layer, and the second refractive index is higher than the first refractive index.
