Abstract

Embodiments of an improved light-direction detection (LDD) device are described herein. The LDD device includes a substrate and at least one predefined structure formed along the substrate by stacking metal layers, contacts, and vias available in the manufacturing process of the device. The predefined structure is formed along a photodiode pair to collectively define an optical sensor configured to detect direction of incident light without need for off-chip components. The device accommodates light direction detection in two or more orthogonal planes.
