(a) The schematic diagram of the proposed reflective angle robust color filtering device. (b) The complex refractive indices of the amorphous silicon film deposited by e-beam evaporation with the substrate at room temperature, 150°C, and 300°C. (c) A photograph of the fabricated RGB devices at normal incidence. (d) The simulated and experimental reflection spectra of the proposed color filters for the three colors of red, green, and red color at normal incidence with the unpolarized light.
