Abstract: The present description concerns an optical filter intended to be arranged in front of an image sensor comprising a plurality of pixels, the filter comprising, for each pixel, a resonant cavity comprising a first transparent layer, interposed between second and third mirror layers, and a diffraction grating formed in the first layer, wherein at least one of the cavities has a different thickness than another cavity.

Abstract: The present description concerns a manufacturing method comprising, for each photodetector of an array of photodetectors of a light sensor, a use of a mask obtained by directed self-assembly of a block copolymer to form, by a first etch step, at least one first structure on the side of a first surface of the photodetector intended to receive light.

Abstract: A metasurface optical component including a first substrate, a set of subwavelength structures for forming a metasurface optic and a layer, referred to as an encapsulation layer, that is substantially parallel to the surface of the first substrate, the encapsulation layer being spaced apart from the set of structures by a space referred to as the encapsulated space, the encapsulation layer and the encapsulated space together forming a multilayer antireflective coating in the given wavelength range.

Abstract: The invention provides an image sensor comprising a light receiving side (Fa) and, in a substrate (100), a photoelectric conversion region (PD) capable of converting light received from the light receiving side (Fa) into a charge, a storage region (SN) capable of storing a charge transferred from the photoelectric conversion region and an optical isolation element of the storage region. The optical isolation element (60) is buried in the substrate between the light receiving side and the storage region.

Abstract: An image sensor including a substrate including first portions containing photodetectors adapted to capturing a radiation and second portions containing electronic components located between come of the first portions; a pixelated filter including filter pixels, at least some of which include an interference filter including a stack of planar layers; and shields reflecting or absorbing said radiation covering the second portions and including walls reflecting or absorbing said radiation extending between filter pixels along at least a portion of the height of the pixelated filter.
