摘要: The present disclosure relates to an image sensor. The image sensor includes a substrate and a photodetector in the substrate. The image sensor further includes an absorption enhancement structure. The absorption enhancement structure is defined by a substrate depression along a first side of the substrate. The substrate depression is defined by a first plurality of sidewalls that slope toward a first common point and by a second plurality of sidewalls that slope toward a second common point. The first plurality of sidewalls extend over the second plurality of sidewalls.

摘要: A system and method are provided for forming electromagnetic energy transmissive layers, which are particularly configured to selectively scatter specific and selectable wavelengths of electromagnetic energy, while allowing remaining wavelengths to pass therethrough. Processes are provided by which to form, or otherwise incorporate, one or more energy scattering layers, including uniquely implementing optical light scattering techniques in such energy scattering layers, and to objects, object portions, wall plates, lenses, filters, screens and the like that are formed of, or that otherwise incorporate, such transmissive energy-scattering layers. Refractive indices of particles fixed in a matrix are tunable in order that the finished layers provide an opaque appearance when viewed from an energy-incident excited by light in the visible spectrum. A color, pattern, texture or image of the scattering layer may be rendered according to an individual user's desires, the layers being substantially-transparent to light passing through layers.

摘要: A system and method are provided for forming one-way light transmissive layers implementing optical light scattering techniques in those layers, and to objects, object portions, lenses, filters, screens and the like that are formed of, or that otherwise incorporate, such one-way light transmissive layers. Processes are provided by which to form, or otherwise incorporate, one or more one-way light transmissive, or substantially transparent, object portions or layers in solid or hollow objects Individual one-way light transmissive layers are formed of substantially-transparent sub-micrometer spheres, including micro-particles and/or nano-particles, with nano-voids incorporated between them. Refractive indices of the sub-micrometer particles are tunable in order that the finished layers provide an opaque appearance when viewed from a light incident side that is rendered according to an individual user's desires, but that are substantially-transparent to light passing through the finished layers to areas or sensors behind those finished layers.

摘要: A photodetector with an integrated reflective grating structure includes a substrate, an active layer disposed on the substrate, and a grating structure disposed between the substrate and the active layer. A first doped region is formed on the substrate at a location near the grating structure. A second doped region is formed on a surface of the active layer away from the grating structure. The doping type of the second doped region is different from that of the first doped region.

摘要: A method of making a plasmonic metal/graphene heterostructure comprises heating an organometallic complex precursor comprising a metal at a first temperature T1 for a first period of time t1 to deposit a layer of the metal on a surface of a heated substrate, the heated substrate in fluid communication with the precursor; and heating, in situ, the precursor at a second temperature T2 for a second period of time t2 to simultaneously form on the layer of the metal, a monolayer of graphene and a plurality of carbon-encapsulated metal nanostructures comprising the metal, thereby providing the plasmonic metal/graphene heterostructure. The heated substrate is characterized by a third temperature T3. The plasmonic metal/graphene heterostructures, devices incorporating the heterostructures, and methods of using the heterostructures are also provided.

摘要: The light detector includes: a substrate including at least one light receiving area and a light incident surface on which light is incident; and a meta-lens formed on the light incident surface of the substrate to focus the light incident on the light incident surface. When viewed from the thickness direction (Z-axis direction) of the substrate, the meta-lens is formed so as to overlap both an adjacent region adjacent to the light receiving area and a peripheral region that is continuous with the adjacent region and is a region inside the light receiving area along the outer edge of the light receiving area. When viewed from the Z-axis direction, a non-forming region in which the meta-lens is not formed is provided in a region overlapping a central region of the light receiving area in the light incident surface.
