Figure 1

(a) Schematic of a transmissive color filter array based on stepwise FP cavities. (b) Schematic showing the cross-section profile of a unit of the FP cavity arrays, in which both the height (h) and the size (D) of dielectric structures are variable parameters to tune the colors. (c) The fabrication process flow to obtain the color filter array.
