Abstract
A semiconductor-based sensor with enhanced light absorption, and in particular, enhanced infrared light absorption 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 light absorption is enhanced.
