Abstract

A device for color imaging including an optical sensor having light sensitive pixels with a metal film disposed over the light sensitive pixels. The metal film has a group of nano-holes arranged over the pixels according to a periodic lattice formation and is configured to pass light of a preselected first range of wavelengths. The group of nano-holes arranged over an adjoining group of pixels is configured to pass light having ranges of wavelengths different from the first range of wavelengths.
