A structure and method of reducing optical cross talk in an image sensor by using a light shield having light shield portions comprising a plurality of separated blocks of opaque material above each pixel cell's photosensor. The light shield portions have an aperture allowing light to pass through to the photosensor associated with the pixel cell. The blocks are separated from each other by a distance shorter than the wavelength of visible light; as such, the space created between the blocks mitigates the passing of wavelengths of incident light therethrough to undesired areas. ® KIPO & WIPO 2009
