Abstract: An optical filter is provided. The optical filter includes a plurality of metal layers, and a dielectric body layer disposed between two adjacent metal layers of the plurality of metal layers. Each of the plurality of metal layers is formed with a plurality of slits, and the plurality of slits formed in one of the adjacent metal layers do not overlap with the plurality of slits formed in the other of the adjacent metal layers in a normal direction of the adjacent metal layers.

Abstract: An image capturing apparatus that includes a polarizing filter of a slit type in which polarization characteristics are improved is realized. A polarizing unit (10) of an image capturing apparatus (100) includes a first polarizer layer (120a) and a second polarizer layer (120b) that hold a dielectric layer (14) therebetween, and a plurality of slits (13) that are arranged at regular intervals in a predetermined direction are formed in each of the first polarizer layer (120a) and the second polarizer layer (120b). A forming material of each of the first polarizer layer (120a) and the second polarizer layer (120b) and a forming material of a wiring layer that controls an operation of a light receiving unit (11) are selected from Al, Si, Cu, Au, Ag, Pt, W, Ti, Sn, In, Ga, Zn, and a compound or alloy that contains at least one of the foregoing.

Abstract: Provided are an optical receiver that can realize a reduction in the variation of sensitivity in the ultraviolet light region and a reduction in noise in the visible light region and the infrared light region, a portable electronic device, and a method of producing an optical receiver. The first light-receiving device (PD1) and the second light-receiving device (PD2) of the optical receiver (1) are each constituted by forming a second conductivity-type N-type well layer (N_well) on a first conductivity-type P-type substrate (P_sub), forming a first conductivity-type P-type well layer (P_well) in the N-type well layer (N_well), and forming a second conductivity-type N-type diffusion layer (N) in the P-type well layer (P_well). The P-type substrate P_sub, the N-type well layer (N_well), and the P-type well layer (P_well) are electrically at the same potential or are short-circuited.
