The interval between the first pattern and the second pattern that are adjacent to each other is longer than a period of the structures in the first pattern and a period of the structures in the second pattern.

Abstract: A spectral device includes a polarizing filter and an optical filter. The polarizing filter transmits part of light incident on the polarizing filter, the part of light having a particular polarization component. Light that is incident on and passes through the polarizing filter is converted into linearly polarized light. Light that has passed through the polarizing filter is incident on the optical filter. The optical filter transmits light within a particular frequency range. The optical filter includes a metal layer and a dielectric layer. The dielectric layer is disposed on the metal layer. Multiple slits are formed in the metal layer. The multiple slits are arranged at equal intervals in a predetermined direction. The multiple slits extend in a direction perpendicular to a direction in which the light that has passed through the polarizing filter is polarized.

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.
