Abstract

This paper discusses the enhancement of pixel performance through the integration of diffractive optics, specifically focusing on micro-lenses for increased quantum efficiency and reduced pixel-to-pixel cross-talk in imagers. It explores the shift from classical micro-lenses to Fresnel lens designs, detailing the development of planar micro-lenses using diffraction optics like Fresnel lenses for this purpose.
