Abstract

A 3D imaging device is comprised of a photodetector matrix, a layer of material fixed on a face of the photodetector matrix, the layer of material being capable of absorbing or reflecting light, an opening being formed in said layer of material at each photodetector, a layer of insulating material fixed on said layer of material capable of reflecting or absorbing light, the layer of insulating material having a face surrounding, in the body thereof, a set of G waveguides, each waveguide of the set of waveguides being positioned vertically in relation to said face, opposite an opening, the heights of the different waveguides, considered in relation to the face of the layer of insulating material, defining N distinct levels, N being a whole number greater than or equal to 2.
