Abstract: An integrated circuit that includes a substrate, a photodiode, and a Fresnel structure. The photodiode is formed on the substrate, and it has a p-n junction. The Fresnel structure is formed above the photodiode, and it defines a focal zone that is positioned within a proximity of the p-n junction. In one aspect, the Fresnel structure may include a trench pattern that functions as a diffraction means for redirecting and concentrating incident photons to the focal zone. In another aspect, the Fresnel structure may include a wiring pattern that functions as a diffraction means for redirecting and concentrating incident photons to the focal zone. In yet another aspect, the Fresnel structure may include a transparent dielectric pattern that functions as a refractive means for redirecting and concentrating incident photons to the focal zone.

Abstract: An apparatus includes a light senor having directional sensitivity. The light sensor includes multiple light sensitive elements disposed below the same aperture. Each of the light sensitive elements has a respective field of view through the aperture that differs from the field of view of the other light sensitive elements. Signals from the light sensor can facilitate determining the direction of incoming light.
