Abstract
The present disclosure relates to a pixel comprising: a photodiode comprising a portion of a substrate of a semiconductor material, extending vertically from a first face of the substrate to a second face of the substrate configured to receive light; a layer of a first material covering each of the lateral surfaces of the portion; a layer of a second material covering the portion on the side of the first face, first and second material having refractive indexes lower than that of the semiconductor material; and a diffractive structure disposed on a face of the photodiode on the side of the second face.
