Abstract

A light sensor for spectrally resolved light detection, said light sensor comprises: an upper reflective element; a lower reflective element; a photo-sensitive element therebetween; a spacer element, configured to form the lower reflective element or arranged between the upper and the lower reflective element; wherein the elements form a stack of layers which define a resonance structure between the upper and the lower reflective element for providing a resonance of light; wherein the spacer element comprises at least two different materials, a distribution of which is different between different pixels in an array of pixels such that a resonance wavelength is different for different pixels; and wherein for a plurality of pixels, geometrical structures smaller than the resonance wavelength are defined by the at least two different materials.
