Abstract:The development of a filterless imager has been eagerly awaited to overcome the diffraction limit when pixel sizes decrease to subwavelength scales. We propose an architecture for a filterless imager based on a symmetric inversely stacked radial junction (RJ) PINIP photodetector over silicon nanowires (SiNWs), whereby the diameter of which is less than 500 nm, which preliminarily displays the capability of bias-selected and tunable spectrum responses to the R, G, and B color bands. Assisted via suitably traine… Show more
