Abstract
A semiconductor-based sensor to detect light angle of incidence includes a semiconductor light sensor element and a patterned spatially inhomogeneous dielectric layer disposed over the semiconductor light sensor element. Characteristically, spatial inhomogeneity of the patterned spatially inhomogeneous dielectric layer is optimized to provide a maximized electric field in the semiconductor light sensor element such that the semiconductor-based sensor is operable to detect one or more incident angles of light at a predefined wavelength or wavelengths of light.
